+
+ Backwards compatibility breaks and advisories
+ ===============================================
+
+ +---------------------------------------------------------------------------------------+
+ o [24-12-2010] | Stable release |
+ +---------------------------------------------------------------------------------------+
+
+ o [04-12-2010] chart.key.vpos is now silently converted to chart.key.position.y (note that these two properies behave slightly
+ differently - chart.key.position.y is an absolute coordinate). ALSO; the key has been rewritten, so check that
+ your graphs are working as you expect
+ o [04-12-2010] The HBar labels (from chart.labels.above) now have an extra property (chart.labels.above.decimals) which controls
+ how many decimals are shown. This defaults to 0, and as a result you may need to set this if you're expecting decimals.
+
+ +---------------------------------------------------------------------------------------+
+ o [27-11-2010] | Stable release |
+ +---------------------------------------------------------------------------------------+
+
+ o [20-11-2010] For the line/bar/scatter, when the X axis is at the bottom and there is a background bar with a
+ negative start (or it results in a negative end value), you now get a warning.
+ o [13-11-2010] All line chart labels are now shown, regardless of how many points on the line there are.
+ o [06-11-2010] The HBar and Scatter have had their scaled handling changed slightly - now if you specify a maximum Y value,
+ that is what is used.
+ o [06-11-2010] The API function RGraph.getSCale(max, obj) now takes two arguments - the maximum value and the graph object.
+
+ +---------------------------------------------------------------------------------------+
+ o [30-10-2010] | Stable release |
+ +---------------------------------------------------------------------------------------+
+
+ o [30-10-2010] The Scatter chart can now only have 1/3/5 labels
+ o [30-10-2010] The Line chart can now only have 1/3/5 labels
+ o [23-10-2010] The Bar chart can now only have 1/3/5/10 labels
+ o [23-10-2010] The default for chart.scale.decimals has changed, as such you may need to specify this:
+ myScatter.Set('chart.scale.decimals', 0);
+ o [09-10-2010] Scatter chart ticksize has changed behaviour slightly, you therefore may need to alter it slightly.
+
+ +---------------------------------------------------------------------------------------+
+ o [25-09-2010] | Stable release |
+ +---------------------------------------------------------------------------------------+
+
+ o [18-09-2010] For IE9 compatibility purposes, the IE8 DirectX shadow has been removed from the ModalDialog. This only affects
+ MSIE8. The background is still semi-opaque.
+ o [18-09-2010] The common function RGraph.isIE9() has changed to RGraph.isIE9up(). The old one will continue to work, but
+ not indefinitely.
+ o [11-09-2010] The Odometer properties chart.units.pre and chart.units.post have now changed to chart.value.units.pre
+ and chart.value.units.post. The properties chart.units.post and chart.units.pre are now used for the main
+ labels.
+ o [04-09-2010] HBar and Pie charts have been moved to DOM2 event registration for tooltips
+ o [04-09-2010] The RGraph.number_format() function has had its argument list changed
+ o [04-09-2010] Now that RGraph is moving to DOM2 event handlers, tooltips will be incompatible with IE8
+
+ +---------------------------------------------------------------------------------------+
+ o [28-08-2010] | Stable release |
+ +---------------------------------------------------------------------------------------+
+
+ o [28-08-2010] Removed option to have the labels on the outside of a Meter. Now they're always on the inside of the Meter
+ and there's always 11 of them (including zero)
+ o [14-08-2010] Changed the HBar property chart.strokecolor to chart.strokestyle
+ o [07-08-2010] The Odometer property chart.needle.thickness has been changed to chart.needle.width. Work has been done on the
+ needle head.
+ o [07-08-2010] Progress bar has now been split into two different graph types:
+ o HProgress
+ o VProgress
+ o [07-08-2010] Progress bar property chart.color is now chart.colors, and should be an array
+ o [07-08-2010] Changed default Bipolar colors to just one - green
+
+ +---------------------------------------------------------------------------------------+
+ o [31-07-2010] | Stable release |
+ +---------------------------------------------------------------------------------------+
+
+ o [17-07-2010] Stepped line charts and their tickmarks have been marginally altered. No final tickmark is now shown (it looks
+ odd being isolated)
+ o [17-07-2010] Changed the Odo chart.needle.style to chart.needle.color
+ o [17-07-2010] The Odo properties chart.start, chart.end and chart.value have all been changed to internal properties:

+ o o------------------------------------------------------------------------------------------------------------------o
+ | IMPORTANT ! |
+ | Every single one of the property names has been changed to be a little more unified. The new format is now |
+ | "chart.xxx" where xxx is the actual name. Some of the names have been changed completely, eg. "chart.text.size", |
+ | which was formerly "textheight", whilst others only marginally. This was necessary to bring some semblance of |
+ | uniformity to the RGraph properties across all of the libraries, make it look a bit more "proffessional" and |
+ | provide plenty of scope for future properties. |
+ | |
+ | You should also note that as of this release (14th March 2009) that RGraph has been changed to use the canvas |
+ | text and shadow APIs. This may mean you needing to upgrade your browser if you want to use the latest version. |
+ | At the time of writing, this meant Firefox 3.1b2, Safari 4 and Chrome 2. If you don't wish to upgrade your |
+ | browser, or need Opera support, then you will need to remain on the 28th February 2009 version. |

+
+ <p>
+ Since 24th May 2010 you have had the ability to adjust your graphs interactively. Currently the Bar chart, Line chart,
+ Progress Bar, Rose chart and the Tradar have this facility. Some graph types use multiple event handlers and as such
+ are unlikely to work well with other dynamic features. The Line chart is an example of this, and whilst it does work
+ with the context menu (and so the full canvas zoom), it is unlikely to work with other dynamic features.
+ </p>
+
+
+ <p>
+ At the current time this feature on the Bar and Line charts don't work with X axis in the center.
+ </p>
+
+
+ <p>
+ If your intention is to make some sort of interactive console, new HTML5 input types may also be of interest (for example the new <i>range</i> input type
+ which gives you a "slider bar"). Eg (Chrome/Safari/Opera):
+ </p>
+
+ <p style="text-align: center">
+ <input type="range" min="0" max="100" value="76" onchange="document.getElementById('range_result').value = this.value"/>
+ <input type="text" id="range_result" size="3" value="76" />

This is provided in the RGraph Archive.</li><li>Use another browser entirely. Your choices are Firefox 3.5+, Chrome 2+, Safari 4+ or Opera 10.5+. </li></ul> <b>Note:</b> Internet Explorer 9 fully supports the canvas tag. Click <a href="http://groups.google.com/group/rgraph/browse_thread/thread/c5651ff8c56b8f3c#" target="_blank">here</a> to see some screenshots.</div>');

+ </script>
+
+ <div style="float: right">
+ <canvas id="myRose" width="300" height="300">[No canvas support]</canvas>
+ </div>
+
+ <p>
+ Animating your graphs is a relatively easy affair, whilst not being supported natively as it would only serve to
+ over-complicate the RGraph libraries. The way to do it is to use
+ the function <i>RGraph.Clear(canvas)</i>, passing it your canvas object that is returned by
+ <i>document.getElementById()</i>. By default this will cover the canvas in white. You can change this by
+ passing it the color you want it to use as the second (optional) argument. You could even use a gradient if
+ you wanted. Then you can simply redraw the entire graph.
+ </p>
+
+ <p>
+ One thing you should note, is that you may have to specify the scale manually, to prevent it from changing
+ from frame to frame. This can be done by using the <i>chart.ymax</i> property.
+ </p>
+
+ <p>
+ You can review the source of this page if you need further help. Two global variables are set - the number of frames
+ and the current frame number (which starts at one). The graphs are then drawn with appropriate data
+ (ie the data multiplied by the frame number over the total number of frames). If the frame number is less than
+ the total number of frames, the frame number is incremented and the function (window.onload) is called again
+ after a small delay.

+
+ <p>
+ You can if you prefer use an external library for animation, like jQuery.
+ </p>
+

+ The graph to the right is animated using

+ attributes set.

+ In this instance, the <a href="http://ajax.googleapis.com/ajax/libs/jquery/1.4.4/jquery.min.js" target="_blank">

+ </ul>
+
+ <a name="how"></a>
+ <h4>How do annotations work?</h4>
+
+ <p>
+ Enabling annotations is a very simple affair, and consists of doing the following:
+ </p>
+
+ <pre class="code" style="width: 55%">myGraph.Set('chart.annotatable', true);</pre>
+
+ <a name="browser"></a>
+ <h4>Browser support</h4>
+
+ <p>
+ Annotations are supported in all browsers that RGraph works with - Firefox 3.5+, Chrome 2+, Safari 4+, Opera 10.5+ and
+ MSIE/Google Chrome Frame. They DO NOT however work with MSIE 8/ExCanvas.
+ </p>
+
+ <a name="what"></a>
+ <h4>What can I use annotations for?</h4>
+
+ <p>
+ As mentioned you can use it for presentations, highlighting things to yourself or others or just to have fun drawing (!).
+ </p>
+
+ <a name="persistent"></a>
+ <h4>Are annotations persistent?</h4>
+
+ <p>
+ That depends on which browser you're using. The annotation data is stored in the users web browser (not on the web server),
+ meaning currently (21st March 2010) browser support is limited to Firefox 3.5+, Safari 4+,
+ Chrome 4+ and Opera 10.5+. MSIE 8 also has the required storage capabilities, but since it doesn't yet support canvas, the point is moot.
+ The user does not have to
+ confirm anything for storage to be allowed - try it out on this page by drawing on the graph and then refreshing the page.
+ </p>
+
+ <a name="palette"></a>
+ <h4>How do I show the mini-palette?</h4>
+
+
+ <p>
+ You can show the palette by using the <i>RGraph.Showpalette</i> function shown below as a context menu item:
+ </p>
+
+ <pre class="code">
+myObj.Set('chart.contextmenu', [
+ ['Show palette', RGraph.Showpalette],
+ ['Clear', function () {RGraph.Clear(myObj.canvas); myObj.Draw();}]
+ ]);
+</pre>
+
+ <p>
+ This code will result in the same context menu as the graph above.
+ </p>
+
+ <a name="clear"></a>
+ <h4>How can I clear the annotations?</h4>
+
+ You can simply clear the graph and redraw it:
+
+ <pre class="code">RGraph.Clear(myGraph.canvas); // Clear the graph
+myGraph.Draw(); // Redraw it</pre>
+
+ <p>
+ In the graph above, there is a context menu that allows you to both clear the graph and also demonstrates the mini-palette
+ feature available to you.
+ </p>
+
+ <a name="replay"></a>
+ <h4>Replaying annotations when they're off</h4>
+
+ <p>
+ When annotations are not enabled, any prior annotations that may have been made are not displayed. To show them you need
+ to use the API function <i>RGraph.ReplayAnnotations(object)</i> after the call to .Draw().
+ </p>

+ <h4>Overview</h4>
+
+ <p>
+ Working with RGraph objects is purposefully easy, to make them straight forward to integrate into your own scripts if you want to. For any
+ particular graph type there are a few files required - the common libraries and the graph specific library. Eg:
+ </p>
+
+ <pre class="code">
+<script src="RGraph.common.core.js"></script>
+<script src="RGraph.bar.js"></script>
+</pre>
+
+ <p>
+ <i>RGraph.common.core.js</i> is a function library that contains a large set of functions that support the graph classes.
+ Some functions, and sets of functions, have their own files. For example, the zoom functions reside in <i>RGraph.common.zoom.js</i>,
+ so if you don't need zoom, you don't need this file.
+ Each of the graph libraries (<i>RGraph.*.js</i>) contains that particular graphs class. If you'd like to see a "bare bones"
+ implementation, you can look at the <a href="../examples/basic.html">basic example</a>. There's also a
+ <a href="#skeleton">skeleton example</a> to make it easier to create new graph types.
+ </p>
+
+ <a name="references"></a>
+ <h4>Canvas and context references</h4>
+
+ <p>
+ Each graph object maintains references to the <i>context</i> and <i>canvas</i> as properties. So to get hold of them all you
+ need to do is this:
+ </p>
+
+ <pre class="code">
+<script>
+ window.onload = function ()
+ {
+ // 1/2 First draw the chart
+ var myBar = new RGraph.Bar('myCanvas', [1,5,8,4,6,3,1,5,7,8,4,6]);
+ myBar.Set('chart.labels', ['Jan', 'Feb', 'Mar', 'Apr', 'May', 'Jun', 'Jul', 'Aug', 'Sep', 'Oct', 'Nov', 'Dec']);
+ myBar.Draw();
+
+ // 2/2 Now get hold of the references
+ var context = myBar.context; // Get hold of a reference to the context
+ var canvas = myBar.canvas; // Get hold of a reference to the canvas
+ }
+</script>
+</pre>
+
+ <a name="events"></a>
+ <h4>Working with events</h4>
+
+ <p>
+ When working with events, you may come across the situation where you have a reference to the <i>canvas</i>, but
+ also need to access the graph object. For this reason the constructor of each object adds a reference to the object to the
+ canvas and you can access it like this:
+ </p>
+
+ <pre class="code">
+<script>
+ document.getElementById("myCanvas").onclick = function (e)
+ {
+ var src = (RGraph.isIE8() ? event.srcElement) : e.target;
+
+ // The RGraph object constructors add __object__ to the canvas.
+ var myBar = src.__object__;
+ }
+</script>
+</pre>
+
+ <a name="coords"></a>
+ <h4>Working with graph coordinates</h4>
+
+ <p>
+ For most graph types, the coordinates of elements (eg bars, lines etc) are to be found in the class variable <i>obj.coords</i>.
+ This is usually a multi-dimensional array consisting of the coordinates of those shapes, or of points. As an example the bar
+ chart maintains the X, Y, width and height of each bar (or sections of bars in a stacked bar chart). The coords array is
+ usually a flat array, even when you have multiple sets of data.
+ </p>
+
+ <p>
+ By using the RGraph.getMouseXY() function and this array you can determine if a bar was clicked on, or if the mouse is near a
+ line point etc.
+ </p>
+
+ <pre class="code">
+var myCoords = myBar.coords;
+</pre>
+
+ <p>
+ <b>Note:</b> Previously the coords array values sometimes included the margin values, and sometimes didn't. As of 17th
+ April 2010 the values have all been unified to not include the margin values, so the values are as reported.
+ </p>
+
+ <a name="data"></a>
+ <h4>Working with graph data</h4>
+
+ <p>
+ Another variable you may need is the <i>data</i> variable. For most graph types, this is where the data is stored. It is usually
+ untouched, so it is as you supplied to the graph objects constructor. A notable exception to this is filled line charts.
+ Here the original data is stored in the class variable <i>original_data</i>. The data supplied is modified to produce the stacking
+ effect. If you need to modify a filled line charts data you will need to change this variable instead.
+ </p>
+
+ <p>
+ Not all graph types use the <i>data</i> variable. For some the name is different so that it makes a little more sense. The
+ graph types and their associate data variables are listed below<sup>1</sup>.

+
+ <a name="updating"></a>
+ <h4>Updating your graphs dynamically</h4>
+
+ <p style="background-color: #ffa; padding: 3px; border: 1px dashed black">
+ <b>Note:</b>
+ It is important that you're careful with types when making AJAX requests. Since the response is initially a string,
+ and your AJAX function/library may not do conversions for you, you may need to convert these strings to numbers. To
+ do this you can use the <i>Number()</i> or <i>parseInt()</i> functions. For example:
+ </p>
+
+ <pre class="code">
+<script>
+ num = Number('23');
+ num = parseInt('43');
+</script>
+</pre>
+
+ <p>
+ A common request is to be able to update graphs dynamically. This is quite simple and consists of three steps:
+ </p>
+
+ <ol>
+ <li style="margin-top: 0">Get the new data from the server (with an AJAX request for example).</li>
+ <li style="margin-top: 0">Set the data in your graph object. See the above table for the appropriate property to use.</li>
+ <li style="margin-top: 0">Call the .Draw() method again.</li>
+ </ol>
+
+ <p>
+ If you don't need to get data from your server (ie it's all client-side) then you can omit the first step. Also, it may be
+ sufficient to simply recreate the entire object from scratch. This means that you won't have to alter and
+ RGraph internal properties - just recreate the graph object and configuration. There's a simple function
+ you can use for AJAX purposes <a href="index.html#ajax">here</a>.
+ </p>
+
+
+ <a name="accessors"></a>
+ <h4>Setting properties</h4>
+
+ <p>
+ To set RGraph properties, ideally you should use each objects setter (there's also a corresponding getter). These functions
+ accomodate some backwards compatibility changes, so by not using them you run the risk of your graphs not working entirely as
+ expected.
+ </p>
+
+ <pre class="code">
+myObj.Set('chart.gutter', 25);
+myObj.Get('chart.gutter');
+</pre>
+
+ <a name="references.other"></a>
+ <p> </p>
+ <h4>References available on RGraph objects</h4>
+ <p>
+ RGraph stores various references to objects on the canvas (typically) to make getting hold of them easier. There's also a
+ Registry object in
+ which references are stored. Typically the objects are named with the format <i>__xxx__</i>, and you can inspect the
+ objects by using a console(eg the inspector that's part of Google Chrome - <i>CTRL+SHIFT+J</i>). Some examples are:
+ </p>
+
+ <ul>
+ <li>__object__ on the canvas - a reference to the graph object</li>
+ <li>
+ RGraph.Registry.Get('chart.tooltip') - a reference to the currently visible tooltip. This in turn has the following
+ available:
+ <ul>

+ <a name="scale"></a>
+ <h4>Scale information</h4>
+ <p>
+ For the Bar, Bipolar, HBar, Line and Scatter charts the scale that is used is stored in the <i>scale</i> class variable. Eg:
+ </p>
+
+ <pre class="code">
+<script>
+ var myBar = new RGraph.Bar('cvs', [56,43,52,54,51,38,46,42,52]);
+ myBar.Draw();
+
+ var myScale = myBar.scale
+</script>
+</pre>
+
+ <a name="text"></a>
+ <h4>Adding text to your graphs</h4>
+ <p>
+ If you want to add arbitrary text to your graph(s) you can use the API function <a href="#functions.other">RGraph.Text().</a>
+ </p>
+
+ <pre class="code">
+<script>
+ // Draw a basic graph

+ </li>
+ </ul>
+
+ <a name="functions.numbers"></a>

+ <h4>Miscellaneous</h4>
+
+ <ul>
+ <li>
+ <b>(object) RGraph.FixEventObject(event)</b><br />Pass this function an event object and it will attempt to "fill in" the missing properties (depending on the browser).

+ <li>
+ <b>(null) RGraph.ClearAnnotations(id)</b><br />This function clears the annotation data associated with the given canvas ID (but DOES NOT redraw the graph). If you want to clear the visible annotations too, you will need to redraw the canvas. You could do this using the following code:
+ <br />
+ <pre class="code">
+function ClearAndRedraw (obj)
+{
+ RGraph.Clear(obj.canvas); // This function also calls the RGraph.ClearAnnotations() function
+ obj.Draw();
+}</pre>
+ <br /><i>File: RGraph.common.annotatate.js</i><p />
+ </li>
+ <li><b>(null) RGraph.ReplayAnnotations(object)</b><br />This function redraws any annotations which have previously been drawn on the canvas. You would use this function when annotations are turned off and you want previous annotations to be displayed.<br /><i>File: RGraph.common.annotate.js</i><p /></li>
+ <li><b>(array) RGraph.getMouseXY(event)</b><br />When passed your event object, it returns the X and Y coordinates (in relation to the canvas) of the mouse pointer.

+ <li><b>(array) RGraph.getCanvasXY(event)</b><br />Similar to the above function but returns the X/Y coordinates of the canvas in relation to the page.<br /><i>File: RGraph.common.core.js</i><p /></li>
+ <li><b>(number) RGraph.degrees2Radians(number)</b><br />Converts and returns the given number of degrees to radians. 1 radian = 57.3 degrees.<br /><i>File: RGraph.common.core.js</i><p /></li>
+ <li><b>(array) RGraph.getScale(max, obj)</b><br />Given the maximum value this will return an appropriate scale. The second argument is the graph object.<br /><i>File: RGraph.common.core.js</i><p /></li>
+ <li><b>(mixed) RGraph.Registry.Get(name)</b><br />In conjunction with the next function, this is an implementation of the Registry pattern which can be used for storing settings.<br /><i>File: RGraph.common.core.js</i><br /><br /></li>
+ <li><b>(mixed) RGraph.Registry.Set(name, value)</b><br />In conjunction with the previous function, this is an implementation of the Registry pattern which can be used for storing settings.<br /><i>File: RGraph.common.core.js</i><br /><br /></li>
+ <li><b>(null) RGraph.Register(object)</b><br />This function is used in conjunction with the next to register a canvas for redrawing. Canvases are redrawn (for example) when tooltips or crosshairs are being used.<br /><i>File: RGraph.common.core.js</i><br /><br /></li>
+
+ <li>
+ <b>(null) RGraph.Redraw([id, [color]])</b><br />This function is used in conjunction with the previous to redraw a canvas. Canvases are redrawn (for example) when tooltips or crosshairs are being used.<br /><br /> <b>Note:</b> All canvases that are registered are redrawn. However the optional first argument can be an ID (a string) of the canvas that is NOT to be redrawn. The optional second argument is the color to use when clearing canvases.<br /><i>File: RGraph.common.core.js</i><br /><br />
+ </li>
+
+ <li><b>(null) RGraph.SetShadow(object, color, offetX, offsetY, blur)</b><br />This function is a shortcut function used to set the four shadow properties. The arguments are: your graph object, the shadow color, the X offset, the Y offset, the shadow blur.<br /><i>File: RGraph.common.core.js</i><br /><br /></li>
+ <li><b>(null) RGraph.NoShadow(object)</b><br />This function is a shortcut function used to "turn off" the shadow. The argument is your graph object.<br /><i>File: RGraph.common.core.js</i><br /><br /></li>
+ <li><b>(array) RGraph.getSegment(event)</b><br />This function can be used with the Pie (including the donut variant) and Rose charts to get segment information when the canvas is clicked on (or the mouse is moved). It returns an array consisting of: <p /><ul><li>The center X coordinate</li><li>The center Y coordinate</li> <li>The radius</li><li>The start angle (in degrees)</li><li>The end angle (in degrees)</li></ul><br />Angles are measured starting from the "east" axis.<br /><i>File: RGraph.common.core.js</i><br /><br /></li>
+ <li>
+ <b>(number) RGraph.Async(mixed[, delay])</b><br />This is a simple function but has significant implications on your pages performance. You
+ can pass this either a function pointer, or a string containing the code to run and it will run the code asynchronously (ie in
+ parallel to the page loading). In doing so it can mean that your page is displayed faster, as the graph is created
+ seperate to the page loading. As such, the placement of your canvas tag becomes more important. What you can do is
+ define the canvas tag and then the code to produce the graph immediately after it. This is how the front page is coded,
+ (but not using the RGraph.Async() function).
+ There's an example of it <a href="async.html">here</a>. The optional delay argument is measured in milliseconds
+ (1 second = 1000 milliseconds) and defaults to 1. What you can do is specify something like 1000 to make the effect
+ more pronounced to ensure it's working as expected.
+
+ <p>
+ <b>Note:</b> Since a dev release of version 4, Google Chrome versions 4 and 5 have an issue with rendering text when using
+ the RGraph.Async() function. The solution here is to simply not use the RGraph.Async() function.

+ <pre class="code">myBar.Set('chart.contextmenu', [
+ <span style="color: green">['Get PNG', RGraph.showPNG]</span>,
+ null,
+ ['Cancel', function () {}]
+ ]);</pre>
+ Optionally, you can pass in the canvas as an argument which will be used, meaning now you do not have to use a
+ context menu (there's an example <a href="png.html"><b>here</b></a>). It WAS originally designed to be used with a context menu, hence it's part of the <i>RGraph.core.context.js</i>

+
+ <p>
+ Asynchronous processing can speed up the display of your graphs, because the browser gets to your code, sets it
+ going and then continues on rendering the page. Particularly if you have a weighty page,
+ it can make quite a difference. The <i>RGraph.Async()</i> function itself is very simple, but because it can make
+ a significant difference to the speed of your page, it is documented here. There's an example of it to the right.
+ One thing to remember is to ensure your canvas tag is defined first before you set the function that creates
+ the graph going.
+ </p>
+
+ <p>
+ Although asynchronous processing can speed up your pages, it can also give the appearance of slower pages due to partial
+ rendering, (ie your pages render a bit at a time). You therefore will need to experiment to get the best result for you.

+
+ <p><b>Things to remember</b></p>
+
+ <ul>
+ <li>All your libraries must be loaded first. In the pages <head> for example. If not, you won't be able to create your graphs.</li>
+ <li>Your <canvas> tag must be defined before setting the asynchronous code going. If not, then the canvas may be referenced before it exists, and thus your graphs will not be created.</li>
+ <li>
+ The users connection speed may be a factor. Slower connections may mean, for example, that the onload event doesn't fire very
+ quickly. If you're using the onload event to create your graphs then asynchronous creation instead may give you more
+ apparent speed ups. Alternatively, careful placement of the <canvas> tag and the code that creates the graph may suffice
+ instead.
+ </li>
+ <li>Since the MSIE/ExCanvas combo requires you to use the window.onload event, aynchronous graph creation in this case will probably not be any help.</li>
+ <li>
+ Since a dev release of version 4, Google Chrome has had an issue when aynchronous processing is used, meaning that
+ text isn't always displayed. The solution here is simply to not use asynchronous processing. As of 27th March 2010,
+ Chrome 5 appears to be fine.
+ </li>

+
+ <p>
+ You will probably want to know the different ways you can define a color. There are a few
+ ways which you can use, all of which are quite straight-forward.
+ </p>
+
+ <ul id="colors">
+ <li><a href="#named">Named colors</a></li>
+ <li><a href="#hex">Hex values</a></li>
+ <li><a href="#rgb">RGB values</a></li>
+ <li><a href="#rgba">RGBA values</a></li>
+ <li><a href="#hsl">HSL values</a></li>
+ <li><a href="#hsla">HSLA values</a></li>
+ <li><a href="#lgradients">Linear gradients</a></li>
+ <li><a href="#rgradients">Radial gradients</a></li>
+ <li><a href="#info">More information</a></li>
+ </ul>
+
+ <a name="named"></a>
+ <br /> <br />
+ <h2>Named colors</h2>
+
+ <p>
+ The first, and easiest, is to use named colors. This gives you a range of color values that have been predefined for you. Eg:
+ </p>
+
+ <pre class="code">myObject.Set('chart.colors', ['red', 'blue']);</pre>
+
+ <a name="hex"></a>
+ <br /> <br />
+ <h2>Hex values</h2>
+
+ <p>
+ The next, is straight forward hex values like you can use in normal CSS. These consist of a hash sign,
+ followed by three or six hexadecimal characters. Eg:
+ </p>
+
+ <pre class="code">myObject.Set('chart.colors', ['#f00', '#0000ff']);</pre>
+
+ <a name="rgb"></a>
+ <br /> <br />
+ <h2>RGB values</h2>
+
+ <p>
+ Also as used in CSS, RGB values are the same as what you can use in CSS. Eg:
+ </p>
+
+ <pre class="code">myObject.Set('chart.colors', ['rgb(255,0,0)', 'rgb(0,0,255)']);</pre>
+
+ <a name="rgba"></a>
+ <br /> <br />
+ <h2>RGBA values</h2>
+
+ <p>
+ Probably new to most people, is rgba(). Similar to regular rgb() values, but with a fourth value that allows you to specify the
+ alpha value, which stipulates how transparent the color is. An alpha value of 0 is totally transparent, and a value of 1, is
+ totally opaque (ie. you can't see through it). With a value of 1, rgba() acts exactly like rgb(). This example gives you red
+ and blue colors that are semi-transparent:
+ </p>
+
+ <pre class="code">myObject.Set('chart.colors', ['rgba(255,0,0,0.5)', 'rgba(0,0,255,0.5)']);</pre>
+
+ <a name="hsl"></a>
+ <br /> <br />
+ <h2>HSL() values</h2>
+
+ <p>
+ Also probably quite new to you, are hsl() values. Much like rgb(), but instead of red green and blue, it allows you to specify
+ the Hue, Saturation and Light values instead. For example:
+ </p>
+
+ <pre class="code">myObject.Set('chart.colors', ['hsl(255, 100%, 50%)', 'hsl(169, 100%, 50%)']);</pre>
+
+ <a name="hsla"></a>
+ <br /> <br />
+ <h2>HSLA() values</h2>
+
+ <p>
+ Much like rgb() and rgba(), hsl() has a corresponding hsla() version, which allows you to specify an alpha (transparency) value.
+ Eg:
+ </p>
+
+ <pre class="code">myObject.Set('chart.colors', ['hsla(255, 100%, 50%, 0.5)', 'hsla(169, 100%, 50%, 0.5)']);</pre>
+
+ <a name="lgradients"></a>
+ <br /> <br />
+ <h2>Linear gradients</h2>
+
+ <p>
+ Gradients can be used in place of color values. You can create a linear gradient like so:
+ </p>
+
+ <pre class="code">myGradient = myObject.context.createLinearGradient(0,0,0,250);
+myGradient.addColorStop(0, 'red');
+myGradient.addColorStop(1, 'blue');</pre>
+
+ <p>
+ This creates a gradient that goes from red to blue. The gradient starts at 0,0, and finishes at 0,250. ie A vertical
+ gradient. You may not see the whole gradient - that depends on the extent of the shape you're filling. You can use the gradient
+ in place of a regular color definition. Eg:
+ </p>
+
+ <pre class="code">myObject.Set('chart.colors', [myGradient]);</pre>
+
+ <a name="rgradients"></a>
+ <br /> <br />
+ <h2>Radial gradients</h2>
+
+ <p>
+ Radial gradients are much like their linear counterparts, but circular, as the name suggests. Eg:
+ </p>
+
+ <pre class="code">myGradient = myObject.context.createRadialGradient(0,0,0,0,0,100);
+myGradient.addColorStop(0, 'red');
+myGradient.addColorStop(1, 'blue');
+</pre>
+
+ <p>
+ Instead of four arguments, it takes six - the coordinates of the start point along with the radius, and the coordinates
+ of the end point, along with the radius. After it has been created, you can treat as you would a linear gradient:
+ </p>
+
+ <pre class="code">myObject.Set('chart.colors', [myGradient]);</pre>
+
+ <a name="info"></a>
+ <br /> <br />

+
+ <p>
+ This is an example of combining Bar and Line charts. It's quite straight-forward, and the code here shows you how it can be achieved.
+ </p>
+
+ <p>
+ If the values for the line and bar result in different Y scales you may need to specify the <i>chart.ymax</i> property for each graph
+ so that the scales are the same. The line turns off Y labels so as not to overwrite the Bars labels.
+ </p>
+
+ <b>Tooltips</b>
+
+ <p>
+ You can have tooltips on the Line chart by setting <i>chart.tooltips.highlighting</i> to <i>false</i>, like below.
+ The order in which you create the graphs is also important, you must define the Bar chart first, and subsequently the Line
+ chart.
+ </p>
+
+ <pre class="code">line.Set('chart.tooltips.highlighting', false);</pre>
+
+ <p>
+ Because the tooltips are only triggered by the Line chart, you should put all of the information, for both the Line and the
+ Bar chart, in the tooltips.

+ Another type of chart you may want is a line chart with Y axes on both sides, as illustrated on the right. You should
+ be careful with this chart type as it can easily lead to confusion.
+ </p>
+
+ <p>
+ This chart is made up from two line charts, one with the Y axis on the left and one on the right. The code that makes up
+ this chart is below.
+ </p>
+
+ <p>
+ The only reason to combine line charts is to get Y axes on the left and right. If you simply want mutiple lines,
+ you can do this without combining any charts. <a href="../examples/line.html">See the line chart example page</a>

+ <br /> <br />
+ <h3>What are context menus?</h3>
+
+ <p>
+ Context menus are what you see when you click your right mouse button. With RGraph, you can specify custom menus
+ for your graphs if you wish. This way you can define custom actions to be associated with menu items. Context menus are a
+ very easy way to extend the functionality of your graphs, allowing you to associate presentation style functionality
+ with them.
+ </p>
+
+ <p>
+ <b>Important:</b> Opera does not allow you to customise the context menu, so with this browser you
+ should use the left mouse button on the graph, instead of the right.
+ </p>
+
+ <a name="look"></a>
+ <br /> <br />
+ <h3>What do they look like?</h3>
+
+ <img src="../images/context.png" width="148" height="90" alt="An RGraph context menu" style="float: right; margin-right: 200px; border: 2px dashed gray; margin-right: 280px" />
+
+ <p>
+ Context menus look like the image on the right. You can of course customise their look by using stylesheets. The CSS classes
+ you need to use are <b>RGraph_contextmenu_background</b>, <b>RGraph_contextmenu</b> and <b>RGraph_contextmenu_item</b>. Eg:
+ </p>
+
+ <br clear="all" />
+
+ <pre class="code">
+<style type="text/css">
+ .RGraph_contextmenu {
+ }
+
+ .RGraph_contextmenu_item {
+ }
+
+ .RGraph_contextmenu_background {
+ }
+</style></pre>
+
+ <p>
+ The "! important" is not necessary if you're not overriding a style that is set by the graph script. If you're having trouble,
+ it's a good idea to use it though.
+ </p>
+
+ <a name="multiple"></a>
+ <br /> <br />
+ <h3>Can I have multiple levels of menus?</h3>
+
+ <p>
+ Yes, as of 24th April 2010 you can have a dual level context menu, which can reduce "option overload" in your user interface.
+ This example defines a simple context menu:
+ </p>
+
+ <pre class="code">
+bar.Set('chart.contextmenu', [
+ ['Zoom', RGraph.Zoom],
+ ['Application', <span style="color: green">[['Login...', function () {ModalDialog.Show('modaldialog_login', 300);}]]</span> ],
+ null,
+ ['Cancel', function () {}]
+ ]);
+</pre>
+
+ <p>
+ As you can see there could easily get to be a lot of arrays, so it may help you during development to structure your code by using
+ indentation.
+ </p>
+
+ <a name="define"></a>
+ <br /> <br />
+ <h3>How do I define context menus?</h3>
+
+ <p>
+ Defining a context menu is quite a simple affair. Eg:
+ </p>
+
+ <pre class="code">
+myBar.Set('chart.contextmenu', [
+ ['Menu item 1', Callback1],
+ ['Menu item 2', Callback2]
+ ]);</pre>
+
+ <p>
+ As you can see, the value is a two dimension array. The second being an array consisting of a string which is used as the name of the
+ menu item, and a function object (NOT the function name as a string). The function object is the function called when the menu item is selected.
+ </p>
+
+ <a name="seperators"></a>
+ <br /> <br />
+ <h3>Can I have "separators"?</h3>
+
+ <p>
+ Yes. Simply pass null instead of an array as your menu item. Eg:
+ </p>
+
+ <pre class="code">
+myBar.Set('chart.contextmenu', [
+ ['Menu item 1', Callback1],
+ null,
+ ['Menu item 2', Callback2]
+ ]);</pre>
+
+ <a name="bypass"></a>
+ <br /> <br />
+ <h3>How do I bypass them?</h3>
+
+ <p>
+ If for any reason you wish to access the browsers own context menu, you can hold down your CTRL key on your keyboard when you
+ click, and the canvas context menu will be bypassed. Try it on the graph below by holding your CTRL key whilst right clicking.
+ </p>
+
+ <a name="use"></a>
+ <br /> <br />
+ <h3>What can I use them for?</h3>
+
+ <p>
+ Since the context menu items run Javascript functions when selected, you can use them for pretty much
+ anything you want. For example you could make a presentation system, with the context menu controlling which
+ graph is shown on the canvas. For example:
+ </p>
+
+ <div style="text-align: center">
+ <canvas id="myCanvas" width="600" height="200">[No canvas support]</canvas>
+ </div>
+
+ <a name="example"></a>
+ <h3>Is there an example file that uses the CSS classes?</h3>
+
+ <p>
+ You can take a look at the bottom of the <a href="../css/website.css" >CSS file for this website</a>.
+ </p>
+
+ <a name="mac"></a>
+ <br /> <br />
+ <h3>Context menus, Macs, Safari, Opera and MSIE 9</h3>
+
+ <p>
+ Mac Safari, Mac Firefox, Windows Safari and MSIE 9 (beta 1) can have trouble displaying the context menu. So for this reason, for these browsers,
+ the context menu is attached to a double click of the left mouse button. Opera doesn't support customising the context menu so
+ this browser also uses a left mouse button double click to trigger the context menu.
+ </p>
+
+ <script>
+ /**
+ * Shows the bar chart

+ function ShowGraphOne ()
+ {
+ RGraph.Clear(document.getElementById('myCanvas'));

+ <li><a href="#example">An example usage</a></li>
+ <li><a href="#important">! important</a></li>
+ </ul>
+
+ <a name="RGraph_png"></a>
+ <br /> <br />
+ <h2>RGraph_png</h2>
+ <p>
+ This controls the appearance of the PNG image which is shown when you use the context menu option <i>RGraph.showPNG()</i>.
+ </p>
+
+ <a name="RGraph_palette"></a>
+ <br /> <br />
+ <h2>RGraph_palette</h2>
+ <p>
+ This controls the appearance of the mini-palette that can be used with annotating.
+ </p>
+
+ <a name="RGraph_tooltip"></a>
+ <br /> <br />
+ <h2>RGraph_tooltip</h2>
+ <p>
+ This controls the appearance of tooltips. The default is to have them look like Windows tooltips.
+ </p>
+
+ <a name="RGraph_contextmenu"></a>
+ <br /> <br />
+ <h2>RGraph_contextmenu</h2>
+ <p>
+ This controls how context menus appear. The default is similar to the look that Windows XP has.
+ </p>
+
+ <a name="RGraph_contextmenu_item"></a>
+ <br /> <br />
+ <h2>RGraph_contextmenu_item</h2>
+ <p>
+ This controls how individual items on the context menu will appear, for example the default has roughly 25px padding-left
+ to accomodate the left bar.
+ </p>
+
+ <a name="RGraph_contextmenu_background"></a>
+ <br /> <br />
+ <h2>RGraph_contextmenu_background</h2>
+ <p>
+ This is the Windows XP style left vertical bar. By default this is light grey.
+ </p>
+
+ <a name="RGraph_zoom_window"></a>
+ <br /> <br />
+ <h2>RGraph_zoom_window</h2>
+ <p>
+ This is the class to use if you want to customise the mini-zoom window.
+ </p>
+
+ <a name="RGraph_zoomed_canvas"></a>
+ <br /> <br />
+ <h2>RGraph_zoomed_canvas</h2>
+ <p>
+ This is the class to use if you want to customise the full canvas zoom.
+ </p>
+
+ <a name="RGraph_zoomed_area"></a>
+ <br /> <br />
+ <h2>RGraph_zoomed_area</h2>
+ <p>
+ This is the class to use if you want to customise the zoomed area.
+ </p>
+
+ <a name="ModalDialog_background"></a>
+ <br /> <br />
+ <h2>ModalDialog_background</h2>
+ <p>
+ This class controls the dark semi-opaque background for the ModalDialog.
+ </p>
+
+ <a name="ModalDialog_dialog"></a>
+ <br /> <br />
+ <h2>ModalDialog_dialog</h2>
+ <p>
+ This class controls the ModalDialog itself.
+ </p>
+
+ <a name="ModalDialog_topbar"></a>
+ <br /> <br />
+ <h2>ModalDialog_topbar</h2>
+ <p>
+ This class controls the top bar for the ModalDialog. You could, for example, use the <i>display</i> CSS property to
+ hide this if you don't want it.
+ </p>
+
+ <a name="example"></a>
+ <br /> <br />
+ <h2>Example usage</h2>
+ <p>
+ Here is an example of using the CSS classes. At the time of writing, some of the items here were only implemented in newer
+ web browsers:
+ </p>
+
+ <pre class="code">
+<style>
+ .RGraph_png {
+ }
+
+ .RGraph_palette {
+ }
+
+ .RGraph_tooltip {
+ }
+
+ .RGraph_contextmenu {
+ }
+
+ .RGraph_contextmenu_background {
+ }
+
+ .RGraph_contextmenu_item {
+ }
+
+ .RGraph_zoom_window {
+ }
+
+ .RGraph_zoomed_canvas {
+ }
+
+ .RGraph_zoomed_area {
+ }
+
+ .ModalDialog_background {
+ }
+
+ .ModalDialog_dialog {
+ }
+
+ .ModalDialog_topbar {
+ }
+</style>
+</pre>
+
+<a name="important"></a>
+<br /> <br />
+<h2>! important</h2>
+
+ <p>
+ If you're attempting to override default styles, then because of the ordering (ie the script is setting the style AFTER
+ your own CSS) you may need to use the "! important" modifier, for example:
+ </p>
+
+ <pre class="code">
+<style>
+ .RGraph_tooltip {
+ background-color: white ! important;
+ }
+</style>
+</pre>
+</body>
+</html>

+ The DOMContentLoaded event is an extremely useful event and can make a big impact on the performance of your pages, hence this
+ example. The DOMContentLoaded event fires when the pages HTML and scripts have loaded, but not necessarily any images or CSS.
+ This can make a big improvement on the apparent speed of your page(s).
+ </p>
+
+ <p>
+ You can read more about the <i>DOMContentLoaded</i> event on the Mozilla site, <a href="https://developer.mozilla.org/en/Gecko-Specific_DOM_Events" target="_blank">here</a>,
+ and the Microsoft site <a href="http://ie.microsoft.com/testdrive/HTML5/87DOMContent-Loaded/Default.html" target="_blank">here</a>.

+ <h4>Introduction</h4>
+
+ <p>
+ Custom events allow you to easily interact with and extend RGraph for your own purposes. The list of available events is below,
+ as is an example of how to make use of them with the <i>RGraph.AddCustomEventListener()</i> function. Event handler functions (ie your
+ functions) are passed a single parameter - the graph object. With this you can get references to the canvas and context. There's
+ an example of this below.
+ </p>
+
+<pre class="code"><script>
+ window.onload = function ()
+ {
+ var line = new RGraph.Line('myLine', [45,12,16,18,44,54,23,21,56]);
+ line.Set('chart.tooltips', ['Fred', 'Barney', 'Jay', 'Pete', 'Frank', 'Bob', 'Ted', 'Lou', 'Kev']);
+ line.Set('chart.labels', ['Fred', 'Barney', 'Jay', 'Pete', 'Frank', 'Bob', 'Ted', 'Lou', 'Kev']);
+ line.Set('chart.hmargin', 5);
+ line.Set('chart.tickmarks', 'dot');
+ line.Draw();
+
+ <span style="color: green">/**
+ * This is the call to the RGraph function that registers the event listener
+ *
+ * line: The graph object
+ * ontooltip: The name of the event
+ * myFunc: The function that handles the event
+ */</span>
+ RGraph.AddCustomEventListener(line, 'ontooltip', myFunc);
+ }
+
+ <span style="color: green">/**
+ * The function that is called when the ontooltip event fires. It is passed a single parameter - the graph object.
+ * With this you can get the ID and references to the canvas and context:
+ * o obj.id
+ * o obj.canvas
+ * o obj.context
+ */</span>
+ function myFunc(obj)
+ {
+ var id = obj.id;
+ var canvas = obj.canvas;
+ var context = obj.context;
+
+ alert('This alert was triggered by the custom ontooltip event');
+ }
+</script>
+</pre>
+
+ <a name="available.events"></a>
+ <h4>Available events</h4>
+
+ <p>
+ <a name="event.ontooltip"></a>
+ <b>ontooltip</b><br />
+ This event fires immediately after a tooltip has been created. This event allows you to easily show graphs in your tooltips (tooltip
+ effects that involve moving the tooltip, eg. <i>contract</i>, <i>expand</i> & <i>snap</i>, will not function). You
+ can find the tooltip object in the RGraph registry - <i>RGraph.Registry.Get('chart.tooltip')</i>. Note that if you're testing and
+ using a function that pauses execution (eg alert()), this will also pause any timers (for animation effects etc). If you want to
+ avoid this you should use a function that doesn't block execution, eg the Firebug/WebKit function, <i>console.log()</i> (you can use the
+ <i>cl()</i> shortcut in RGraph).
+ </p>
+
+ <p>
+ <a name="event.oncontextmenu"></a>
+ <b>oncontextmenu</b><br />
+ This event fires immediately after the RGraph context menu is shown. If you want it, you can get at the context menu in the
+ RGraph registry: <i>RGraph.Registry.Get('chart.contextmenu')</i> Like the <i>ontooltip</i> event, using <i>alert()</i> can
+ pause the fade in timers, so you should consider using the Firebug/Webkit <i>console.log</i> functions instead.
+ </p>
+
+ <p>
+ <a name="event.onbeforedraw"></a>
+ <b>onbeforedraw</b><br />
+ Much like the ondraw event, however this fires at the start of the .Draw() method, in effect "before" the method.
+ </p>
+
+ <p>
+ <a name="event.ondraw"></a>
+ <b>ondraw</b><br />
+ The ondraw event fires <i>after</i> the .Draw() method has run. Note that the interactive features of RGraph may call the .Draw()
+ method multiple times - the zoom in area mode is a prime example.
+ A graph with tooltips is also an example. In this case it would demonstrate that the .Draw() method is called twice (and
+ hence the ondraw event), whereas the ontooltip event only fires once.
+
+ <br /><br />
+
+ <b>Note:</b> The <i>ondraw</i> event is not only fired by its own graph,
+ but (if you're using tooltips for example), can also be fired by other graphs on the page.
+ </p>
+
+ <p>
+ <a name="event.onzoom"></a>
+ <b>onzoom</b><br />
+ The onzoom event fires whenever the canvas is zoomed. When the zoom is in <i>area</i> and <i>canvas</i> modes this fires once,
+ but when in <i>thumbnail</i> mode this event is like the onmousemove event in that it fires whenever the mouse is moved.
+ </p>
+
+ <p>
+ <a name="event.onmodaldialog"></a>
+ <b>onmodaldialog</b><br />
+ The onmodaldialog event fires when the ModalDialog is shown. This event is easily replicated yourself, though using this event
+ may help you to keep your code tidy. This event is utilised slightly differently to the other events:
+
+ <pre class="code">ModalDialog.AddCustomEventListener('onmodaldialog', function () {alert('Hello world!');});</pre>
+ </p>
+
+ <p>
+ <a name="event.onresize"></a>
+ <b>onresize</b><br />
+ The onresize event fires when a canvas is resized. It also fires when the canvas is reset to the original size.
+ </p>
+
+ <p>
+ <a name="event.onadjust"></a>
+ <b>onadjust</b><br />
+ The onadjust event fires whenever one of the supported graph types is adjusted. It usually fires in conjunction with the
+ onmousemove event, and can be blocked by alert(). You therefore may need to use a different function (eg console.log())
+ whilst debugging.
+ </p>
+
+ <p>
+ <a name="event.onannotatestart"></a>
+ <b>onannotatestart</b><br />
+ The onannotatestart event fires at the beginning of the annotating procedure (ie in a similar vein to the onmousedown event).
+ </p>
+
+ <p>
+ <a name="event.onannotate"></a>
+ <b>onannotate</b><br />
+ The onannotate event fires when the graph has been annotated. It fires during the annotate procedure.
+ </p>
+
+ <p>
+ <a name="event.onannotateend"></a>
+ <b>onannotateend</b><br />
+ The onannotateend event fires at the end of the annotating procedure (ie in a similar vein to the onmouseup event).
+ </p>

+ <p>
+ This page shows you how you can easily integrate the graphs with other external Javascript libraries. This particular example
+ attaches a context menu to the graph, of which the only option is to show a login dialog. This could, for example, be used to
+ allow logging in to an admin area.
+ </p>
+
+ <p>
+ The dialog doesn't need to require user input - it could just be a static "Please wait..." type dialog, which is shown while a
+ subsequent page loads that takes a few seconds.
+ </p>
+
+ <p>
+ The ModalDialog was originally an external library, however it's now part of the RGraph package. It's also covered by the
+ RGraph license - so if you have an <a href="licensing.html">RGraph license</a>, then the ModalDialog is part of that.
+ </p>

+ If you're interested in using this modal dialog, then you'll probably also want the CSS that styles it. This can be found in the

+ </p>
+
+ <a name="msie"></a>
+ <h3>Note about Microsoft Internet Explorer 8 and the ModalDialog</h3>
+
+ <p>
+ Microsoft Internet Explorer 8 only supports fixed positioning in strict rendering mode, therefore you must specify a DTD
+ when using this browser. Eg:
+ </p>
+
+ <pre class="code">
+<!DOCTYPE html >
+</pre>
+
+ <a name="hiding"></a>
+ <h3>Hiding the ModalDialog</h3>
+ <p>
+ To hide the ModalDialog (from a "Cancel" button for example), you can use the Close() method:
+ </p>
+
+ <pre class="code">
+<input type="reset" value="Cancel" onclick="ModalDialog.Close()">
+</pre>
+
+ <a name="customising"></a>
+ <h3>Customising the ModalDialog</h3>
+ <p>
+ You can customise the appearance of the ModalDialog by using three CSS classes, which are documented <a href="css.html">here</a>.
+ This page customises the dialog slightly by changing the shadow X/Y offsets:
+ </p>
+
+ <pre class="code">
+<style>
+ /*
+ * These are the CSS classes that you can use to customise the appearance of the ModalDialog. If you're trying to
+ * override something which the scripts set, then because of the ordering you may need to use the "! important"
+ * modifier.
+ */
+
+ /**
+ * This is the semi-opaque background
+ */
+ .ModalDialog_background {
+ }
+
+
+ /**
+ * This is the dialog itself
+ */
+ .ModalDialog_dialog {
+ -webkit-box-shadow: gray 0 0 15px ! important;
+ -moz-box-shadow: 0 0 15px gray ! important;
+ box-shadow: 0 0 15px gray ! important;
+ }
+
+
+ /**
+ * This is gray bar at the top of the dialog
+ */
+ .ModalDialog_topbar {
+ }
+</style>
+</pre>
+
+ <a name="integration"></a>
+ <h3>ModalDialog integration</h3>
+ <p>
+ To integrate the ModalDialog look at the sample code above (the key line is where the context menu is defined). The method you should call is <b>ModalDialog.Show(id, width)</b>.
+ The <i>id</i> is the <i>id</i> of the layer to use. Only the <i>.innerHTML</i> is used, not the layer itself, so it can be hidden by
+ setting the display CSS <i>display</i> property to <i>none</i>. The <i>width</i> is a number which is used as the width of the dialog.
+ </p>
+
+ <p>
+ The only library needed for the ModalDialog to work is <i>RGraph.modaldialog.js</i> - you do not need to use
+ <i>RGraph.common.js</i>. This makes for far smaller download requirements.
+
+ </p>
+
+ <!-- This is the popup dialog-->
+
+ <div id="myDialog" class="modalDialog" style="display: none">
+

+ <h2>Adding events to your Gantt chart</h2>
+
+ <p>
+ To add events, you specify them using the <i>chart.events</i> property. You could use the following to set some events on your gantt chart:
+ </p>
+
+ <pre class="code">gantt.Set('chart.events', [
+ [31, 28, 75, 'Richard'],
+ [12, 28, 67, 'Fred'],
+ [59, 14, 0, 'Barney'],
+ [59, 21, 5, 'Gloria'],
+ [46, 31, 94, 'Paul'],
+ [80, 21, 46, 'Harry'],
+ [94, 17, 84, 'Shane'],
+ [34, 14, 32, 'Barry'],
+ [64, 14, 28, 'Cynthia', 'red', 'yellow'],
+ [13, 61, 74, 'Graham'],
+ [84, 31, 16, 'Paul']
+ ]);
+</pre>
+
+ <p>
+ The first value is the (zero indexed) start number relative to your <i>chart.xmax</i>. So if you have set your <i>chart.xmax</i> to 62, (to represent
+ two months), and this value is 31, the start will be the start of the second month. In this case you could give two labels -
+ <i>['July', 'August']</i>.
+ </p>
+
+ <p>
+ The second value is the duration. So using the previous example, if you set this to 7, you would have an event lasting a week.
+ </p>
+
+ <p>
+ The third value is the "percentage complete" indicator. This is shown to the right of the event, and is optional - you can
+ specify <i>null</i> if you wish.
+ </p>
+
+ <p>
+ The fourth value is the label that is used on the left hand side.
+ </p>
+
+ <p>
+ The optional fifth value stipulates the background colour that the bar is. Default is white.
+ </p>
+
+ <p>
+ And the last optional 6th value is the foreground color of the bar. Defaulting to #0c0.
+ </p>
+
+ <a name="vbars"></a>
+ <h2>Adding vertical bars to your Gantt chart</h2>
+
+ <p>
+ You can add decorative vertical bars like so:
+ </p>
+
+ <pre class="code">gantt.Set('chart.vbars', [
+ [0, 31, 'rgba(192,255,192,0.5)'],
+ [59, 31, 'rgba(192,255,192,0.5)'],
+ [120, 31, 'rgba(192,255,192,0.5)'],
+ [181, 31, 'rgba(192,255,192,0.5)'],
+ [243, 30, 'rgba(192,255,192,0.5)'],
+ [304, 30, 'rgba(192,255,192,0.5)'],
+ ]);
+</pre>
+
+ <p>
+ You can use these for decorative purposes, or to mark events/limits. The first value is the start index, as above.
+ The second value is the unit length, again as above. The third value is the color of the vertical bar.
+ </p>

+ The horizontal bar graph is a variation on the bar chart which can be useful when you have larger labels, since you have

+ <h2>Benefits of HTML5 canvas graphs</h2>
+
+ <p>
+ HTML5 introduces a new HTML element - the CANVAS tag. This tag allows for two dimensional drawing easily using Javascript.
+ This makes it perfect for producing graphs. Because Javascript runs on your users computer, none of the stress on your server
+ normally associated with producing graphs is incurred. Not only that but because
+ of the greater processing power that is typically available on users' computers, they will be much faster. And,
+ because the code can be both compressed (for example if you're using Apache, mod_gzip will do this automatically for you) and
+ cached, bandwidth usage can be massively reduced. This makes it economically attractive to employ, (ie <b>it can save you
+ money...</b>).
+ </p>
+
+ <p>
+ Imagine, you are creating 100,000 graphs a day and the data is such that the resulting graphs cannot be cached. With the RGraph
+ library you can reduce that figure to zero. All the processing and graph creation is done by each individual client, much like
+ rendering the HTML you send to them. So you don't have to send any images, you simply send them the Javascript libraries once.
+ So, much lower bandwidth bills and far less strain on your webserver.
+ </p>
+
+ <p>
+ And if that wasn't enough, because the graphs are created using Javascript, they will work offline if you view a .html page
+ on your own PC. Download the archive and see! Useful if you need to do a presentation for example and want to use the same
+ graph(s) as your website.

+ <br /> <br /> <br />
+ <h2>Browser support</h2>
+
+ <p>
+ Since the graphs are produced using HTML5 features (the new <b>canvas</b> tag), client support is currently:
+ </p>
+
+ <ul>
+ <li>Mozilla Firefox 3.0+</li>
+ <li>Google Chrome 1+</li>
+ <li>Apple Safari 3+</li>
+ <li>Opera 9.5+</li>
+ <li>Microsoft Internet Explorer 8+ (see note)</li>
+ <li>iPhone (text support from iOS v4+)</li>
+ <li>iPad (text support from iOS v4.2+)</li>
+ </ul>
+
+ <p>
+ The HTML5 canvas tag is part of the <a href="http://www.w3.org/html/wg/html5/" target="_blank">HTML5 specification</a>,
+ and all of the above browsers have some sort of support for it.
+ </p>
+
+ <p>
+ <b>Canvas & Microsoft Internet Explorer (MSIE)</b><br />
+ Microsoft Internet Explorer 8 doesn't natively support the HTML5 <canvas> tag. To support
+ MSIE 8 you will need to use either
+ <a href="http://code.google.com/chrome/chromeframe/" target="_blank">Google Chrome Frame</a> or
+ <a href="http://code.google.com/p/explorercanvas/" target="_blank">ExCanvas from Google</a>
+ (which is included in the RGraph archive). Read more about Internet Explorer compatibility
+ <a href="msie.html">here</a>.
+
+ <p />
+
+ <span style="color: #090">
+ Starting with preview 3 <b style="color: black">Microsoft Internet Explorer 9</b> has full support for <canvas>. You can view some screenshots
+ <a href="http://groups.google.com/group/rgraph/browse_thread/thread/c5651ff8c56b8f3c#" target="_blank">here</a>.
+ MSIE 6 and 7 are supported by way of Google Chrome Frame.
+ </span>
+ </p>
+
+ <p>
+ <b>RGraph and older browsers</b><br />
+ Older browsers (eg Chrome 1, Firefox 3, Safari 3, Opera 9.5) are supported, however if they don't support the canvas shadow or
+ text APIs, these will naturally be unavailable. Earlier versions of these browsers may work, but are untested.

+
+ <a name="performance"></a>
+ <br /> <br /> <br />
+ <h2>Improving the performance of your graphs</h2>
+
+ <p>
+ Although performance is excellent, (traditionally your webserver has been
+ producing all of your graphs, and now the client produces them, and typically only one at a time), you may still want to tune
+ RGraph further. The biggest thing you can do is use compression, which reduces the initial download time of the libraries, but
+ there are a number of things you can do:
+ </p>
+
+ <ul>
+ <li>
+ <b>Compression</b><br />HTTP compression can dramatically reduce your bandwidth bills and increase the speed
+ of your website. The RGraph.common.core.js file for example used to be over 100k, but with compression this was reduced
+ to around 17k. Less than a fifth of the original size! <span style="color: red">If you do only one thing to aid performance,
+ then it should be this.</span>
+
+ <p>
+ To achieve this with Apache you have a few options:
+ </p>
+
+ <ul style="list-style-type: disc">
+ <li>You can use the Apache module mod_gzip which compresses the libraries on the fly.</li>
+ <li>
+ You can compress the libraries manually using the gzip command, rename them to remove the .gz suffix
+ and add the header using an Apache directive
+ (eg <span style="background-color: #C5FFC5; padding: 1px">AddEncoding gzip .js</span>). If you have some sort of
+ release process/script, it would make sense to add this to it to automate the procedure.
+ </li>
+ </ul>
+ <p>
+ </li>
+
+ <li>
+ <b>Minification</b><br />
+ Minification reduces the size of the library before compression takes effect, removing unnecessary spaces and comments etc.
+ A combination of minification and compression will give superb results. For example, before being split up into seperate files,
+ minification combined with compression reduced the common library from over 100k to roughly 10k (!). There is a PHP shell
+ script that you can use to minify the libraries in the scripts directory.
+
+ <p>
+ You can get pre-minified versions of the libraries <a href="http://www.rgraph.net/RGraph.minified.zip">here</a>.
+ </p>
+ </li>
+
+ <p>
+
+ <li>
+ <b>Pre-emptive caching</b><br />
+ Slightly different to caching itself, is pre-emptive caching. This involves downloading the libraries before the page that requires
+ them is shown. This way, they're already in the users browser cache and the graph will subsequently appear to be much much
+ quicker. An example of this would be having the library included at the bottom of your index page of your website (optionally
+ with the <b>defer="defer"</b> attribute). The script can be downloaded at will because the page doesn't actually use it, but
+ for subsequent pages it will already be in the users browser cache.
+
+ <p>
+ </li>
+
+ <li>
+ <b>Caching</b><br />
+ Since the libraries you're using won't change that often, you can set distant Expires: headers on them, or appropriate
+ Cache-Control: headers, and the client will not even have to contact your server for it. When you want to make sure
+ the library is re-downloaded (eg. you update the library), then simply change the filename.
+
+ <p>
+ </li>
+
+ <li>
+ <b>Script tag placement</b><br />
+ According to <a href="http://developer.yahoo.com/performance/" target="_blank">Yahoo! guidelines</a> placing the <SCRIPT>
+ tag at the bottom of the page can increase the percieved load time. If you do this, then your graphs should be
+ created in the window.onload event, otherwise the browser may try to create them without the library
+ having been loaded, and will therefore subsequently fail.
+
+ <p>
+
+ You should also consider the effect that this has when your page is rather weighty. If the page is weighty there
+ will be a small delay before the onload event fires, and therefore creates the graph. This might not be so bad if the
+ graph is not immediately visible, however if it is then you should carefully consider using the onload event. You
+ may wish to load the library in the page header, define the canvas tag and then immediately define the javascript that creates the graph. This way
+ the graph will be created and shown, and then the rest of the page loads. The end result is that your graph
+ appears to be faster.
+
+ <p />
+
+ Between the onload event, asychronous Javascript and careful tag placement, you will need to experiment to get the right result
+ for you.
+ </li>
+
+ <li>
+ <b>Document structure</b><br />
+ The structure of your document can have a significant impact on how fast your graphs are displayed. If, for example, you use
+ tables for layout, this can delay the display of elements that are affected by the size of the table. Where possible, you
+ should consider trying to convert your layout to DIVs. An example of this is the front page of this website. The graphs
+ were right aligned using a table as a container. This caused a visible delay when showing them. In this case it was a
+ simple matter to convert the page to use DIVs, and the page subsequently displays much faster.
+ <p />
+ </li>
+
+ <li>
+ <b>Creating your graphs asynchronously</b><br />
+ Where possible, you may wish to create your graphs asynchronously. This allows the browser to continue rendering the page
+ immediately after getting to the code that creates the graph. This might not be perceptible if you don't have a lot of
+ graphs, or your page is small. You can read a little more about this and see example code <a href="async.html">here</a>.
+
+ <p />
+
+ Note that recent releases of Google Chrome (from a dev release of version 4) have had an issue with creating graphs
+ asynchronously, which presents itself by not drawing text sometimes (it's not consistent). Simply not using
+ asynchronous graph production in this case resolves the issue.
+ </li>
+
+ <li>
+ <b>DOMContentLoaded event</b><br />
+ Using this event can speed up the display of your graphs signifcantly compared to the more well known <i>onload</i> event.
+ It is supported by Chrome, Gecko based browsers (ie Firefox), Safari, Opera and Internet Explorer 9. This event fires when
+ the structure of the page is loaded, but not necessarily the images or CSS. This means that if your page is laden with
+ images, this event will fire before the onload event, thus creating your graphs quicker. The effect can be very noticeable.
+
+ <pre class="code">
+function addListener(func)
+{
+ if(window.addEventListener) {
+ window.addEventListener('DOMContentLoaded', func, false);
+ } else {
+ document.attachEvent("onDOMContentLoaded", func);
+ }
+}
+</pre>
+ You can read more about the <i>DOMContentLoaded</i> event on the Mozilla site, <a href="https://developer.mozilla.org/en/Gecko-Specific_DOM_Events" target="_blank">here</a>,
+ and the Microsoft site <a href="http://ie.microsoft.com/testdrive/HTML5/87DOMContent-Loaded/Default.html" target="_blank">here</a>.
+ There's an example <a href="domcontentloaded.html">here</a>.

+ <b>AJAX requests</b><br />
+ If you can take advantage of AJAX, you can use this method to retrieve data from your server. If, for example, you have a graph that
+ shows ongoing information, instead of simply refreshing the entire page, you could use an AJAX request to just retrieve the
+ data that you want and update the graph that way. This reduces the amount of data needed to be transferred, thus reducing the
+ bandwidth used, and will be quicker than a full page refresh, particularly if your page is weighty. There's a simple AJAX
+ function that you can use <a href="#ajax">below</a>.
+ <p />
+ </li>
+
+ <li>
+ <b>Combining libraries</b><br />
+ If your performance requirements are extreme, then you may wish to consider combining the libraries into a single file.
+ This won't save on the size of the individual libraries, but will save on the headers that are sent as part of the response.
+ If a typical response sends 500 bytes worth of headers, and you send four graph libraries, then combining the libraries
+ would save 1500 bytes. Multiple factors need to be considered though, including things like caching, which can circumvent
+ the unneccessary repeated downloading of the libraries.
+
+ <p>
+ Another effect of combining libraries is reducing the amount of HTTP connections needed to retrieve them. Most browsers
+ have a limit on how many connections they can create simultaneously, so if they're not being used to retrieve your
+ graph libraries, they can be used for something else. Reducing the number of HTTP connections also eliminates the time
+ spent setting up those connections.
+ </p>
+ </li>
+ </ul>
+
+ <b>A reasonable performance strategy</b>
+
+ <p>
+ Although there's a lot you can do in regards to performance, a few of the points here will suffice for most
+ websites:
+
+ <ul>
+ <li>Compression</li>
+ <li>Minification</li>
+ <li>Pre-emptive caching</li>
+ <li>Caching</li>
+ </ul>
+
+ The number one thing you should do is compress your libraries. This has multiple benefits and provides by far the most gain,
+ effectively for free. Secondly, use the minified libraries. Since you can download them <a href="../RGraph.minified.zip">here</a>,
+ you might as well use them. Then we have pre-emptive caching. Since most websites won't show graphs on the front page or will
+ have a login page that is shown before any graphs, this effectively eliminates the graph library download. And lastly caching
+ should be done as a matter of course. There's no reason to keep downloading the same library so even caching for only 30 minutes
+ (or the duration of an average visit to your website) will produce results.
+ </p>

+ <h2>Implementing RGraph</h2>
+
+ <p>
+ Getting RGraph up and running is very easy and consists of three steps. If you're having trouble I suggest you get hold of a copy of
+ <a href="http://www.mozilla.com" target="_blank">Firefox</a> along with <a href="http://www.getfirebug.com" target="_blank">Firebug</a> - its
+ Javascript error console will make debugging your issue much easier. Many problems are down to a library not having been included or
+ not using the onload event when you need to. You might also benefit from using the <a href="https://addons.mozilla.org/en-US/firefox/addon/60" target="_blank">Web Developer toolbar</a>
+ for Firefox. This allows you to easily disable caching, thus eliminating any problems that that causes. You could equally use
+ the Chrome developer tools (CTRL+SHIFT+J), optionally in docked mode, which also provides a good quality Javascript console.
+ </p>

+ Add the canvas tag (put it where you want the graph to appear):
+<pre class="code">
+<canvas id="myCanvas" width="600" height="250">[No canvas support]</canvas>
+</pre>
+ </li>
+
+ <li>
+ Create the graph (since it is using the onload event, you can put this anywhere):
+
+<pre class="code">
+<script>
+ window.onload = function ()
+ {
+ var data = [280, 45, 133, 166, 84, 259, 266, 960, 219, 311, 67, 89];
+
+ var bar = new RGraph.Bar('myCanvas', data);
+ bar.Set('chart.labels', ['Jan', 'Feb', 'Mar', 'Apr', 'May', 'Jun', 'Jul', 'Aug', 'Sep', 'Oct', 'Nov', 'Dec']);
+ bar.Set('chart.gutter', 35);
+ bar.Draw();
+ }
+</script>
+</pre>
+ </li>
+ </ol>
+
+ <p>
+ There's also a very <a href="../examples/basic.html">basic example</a> of using RGraph, that does very little. It can be helpful to
+ illustrate how you can get RGraph up and running.
+ </p>
+
+ <h4>Common library split (17th April 2010)</h4>
+ <p>
+ The common library has now been split into separate files. This was because the single common library had become far too large.
+ If you don't use any of the dynamic features, then you still need to change your code, as <i>RGraph.common.js</i> is now
+ called <i>RGraph.common.core.js</i>.
+ </p>
+
+ <a name="structure"></a>
+ <br /> <br /> <br />
+ <h2>Suggested structure for RGraph</h2>
+
+ <img src="../images/structure.png" width="175" height="205" alt="Suggested structure for RGraph" style="float: right" />
+
+ <p>
+ The suggested layout structure for the RGraph libraries is shown on the right. The <b>www.example.com</b> folder represents
+ the root/top level of your website with the <b>javascript</b> directory beneath that. The <b>css</b> and <b>images</b>
+ folders are shown for
+ illustrative purposes only. If you follow this layout then your URLs to the RGraph libraries would be:
+ </p>
+
+ <p>
+ <b>/javascript/rgraph/RGraph.common.core.js</b><br />
+ <b>/javascript/rgraph/RGraph.bar.js</b><br />
+ etc
+ </p>
+
+ <p>
+ By using this structure you make RGraph easy to update should you need to, and also keep all the RGraph libraries in
+ one, easy to find, place.
+ </p>
+
+ <br clear="all" />
+
+ <a name="integration"></a>
+ <br /> <br /> <br />
+ <h2>Integration with server side scripting</h2>
+
+ <p>
+ This is a very easy process, as easy as sending content to the browser. All you need to do is make the <i>data</i> variable
+ (as in the example below) contain the data you want to be displayed. Eg:
+ </p>
+
+ <pre class="code">
+<script src="RGraph.common.core.js"></script>
+<script src="RGraph.line.js"></script>
+
+<canvas id="myCanvasTag" width="600" height="200">[No canvas support]</canvas>
+
+<script>
+ data = [78,16,26,23,25,51,34,64,84,84];
+
+ line = new RGraph.Line("myCanvasTag", data);
+ line.Set("chart.labels", ["Feb", "Mar", "Apr", "May", "Jun", "Jul", "Aug", "Sep", "Oct", "Nov"]);
+ line.Draw();
+</script>
+</pre>
+
+ <p>
+ To get the above using PHP you could do this:
+ </p>
+
+ <pre class="code"><?php
+ // This simply makes a string out of the array of data
+ $myData = join(',', array(78,16,26,23,25,51,34,64,84,84));
+
+ // This prints out the required HTML markup
+ print('<script src="RGraph.common.core.js"></script>' . "\n");
+ print('<script src="RGraph.line.js"></script>' . "\n\n");
+ print('<canvas id="myCanvasTag" width="600" height="200">[No canvas support]</canvas>' . "\n\n");
+ print('<script>' . "\n");
+ print(' var data = [' . $myData . '];' . "\n\n");
+ print(' var line = new RGraph.Line("myCanvasTag", data);' . "\n");
+ print(' line.Set("chart.labels", ["Feb", "Mar", "Apr", "May", "Jun", "Jul", "Aug", "Sep", "Oct", "Nov"]);' . "\n");
+ print(' line.Draw();' . "\n");
+ print('</script>');
+?>
+</pre>
+
+ <p>
+ Strictly speaking the <span style="font-family: Monospace">var</span> isn't necessary, however if you put the code inside a
+ function (like window.onload), it's probably best to do so as using <span style="font-family: Monospace">var</span> will
+ make the variable local, and not global. So doing so will help prevent naming clashes.
+ </p>
+
+
+ <a name="mysql"></a>
+ <br /> <br /> <br />
+ <h4>Integration with PHP & MySQL</h4>
+
+ <p>
+ This is a simple matter of formatting what you get back from MySQL into a string, as the MySQL dump and PHP code
+ below shows (it's based on a database called RGraph_example):
+ </p>

+ UNIQUE KEY `st_day` (`st_day`)
+) ENGINE=MyISAM DEFAULT CHARSET=latin1;
+
+#
+# Dumping data for table `daily_statistics`
+#
+
+INSERT INTO `daily_statistics` VALUES ('Mon', 124);

+INSERT INTO `daily_statistics` VALUES ('Fri', 75);
+INSERT INTO `daily_statistics` VALUES ('Sat', 98);
+INSERT INTO `daily_statistics` VALUES ('Sun', 84);
+</pre>

+ <h4>Making AJAX requests</h4>
+
+ <p style="background-color: #ffa; padding: 3px; border: 1px dashed black">
+ <b>Note:</b>
+ It is important that you're careful with types when making AJAX requests. Since the response is initially a string,
+ and your AJAX function/library may not do conversions for you, you may need to convert these strings to numbers. To
+ do this you can use the <i>Number()</i> or <i>parseInt()</i> functions. For example:
+ </p>
+
+ <pre class="code">
+<script>
+ num = Number('23');
+ num = parseInt('43');
+</script>
+</pre>
+
+ <p>
+ Here is a simple function that you could use to get data from your server using AJAX:
+ </p>
+
+ <pre class="code">
+<script>
+ /**
+ * Makes an AJAX call. It calls the given callback (a function) when ready
+ *
+ * @param string url The URL to retrieve
+ * @param function callback A function object that is called when the response is ready, there's an example below
+ * called "myCallback".
+ */
+ function AjaxCall (url, callback)
+ {
+ // Mozilla, Safari, ...
+ if (window.XMLHttpRequest) {
+ var httpRequest = new XMLHttpRequest();
+
+ // MSIE
+ } else if (window.ActiveXObject) {
+ var httpRequest = new ActiveXObject("Microsoft.XMLHTTP");
+ }
+
+ httpRequest.onreadystatechange = callback;
+
+ httpRequest.open('GET', url, true);
+ httpRequest.send();
+ }
+
+
+ /**
+ * This sample callback function is called when the data is ready (readyState=4)
+ */
+ function myCallback ()
+ {
+ if (this.readyState == 4 && this.status == 200) {
+ // Everything is good, the response is received
+ alert(this.responseText);
+ }
+ }
+</script>
+</pre>
+
+ <p>And you would use it like this:</p>
+
+ <pre class="code">
+<script>
+ AjaxCall('http://www.example.com/getSomething.php', myCallback);
+</script>
+</pre>
+
+ <p>
+ There's an example <a href="dynamic.html">here</a> that shows updating your graph dynamically.

+ <ul>
+ <li>The label text</li>
+ <li>The text color</li>
+ <li>The background color</li>
+ <li>This can be 1 or -1 and denotes whether the label should be above or below the line. This has no effect in Bar charts</li>

+ <p>
+ These are some common issues that you should be aware of. If you're having trouble, you may want to look through these to see
+ if any apply to you or may be the source of your problem.
+ </p>
+
+ <a name="tooltips"></a>
+ <h4>Tooltips not working as of the October 2010 release</h4>
+
+ <p>
+ If you're specifying numbers instead of strings for your tooltips, they will not work any more. Simply cast them to
+ strings, like this:
+ </p>
+
+ <pre class="code">
+<span style="color: red">
+// This WILL NOT work any more
+myBar.Set('chart.tooltips', [56, 67, 53]);
+</span>
+<span style="color: green">
+// Do any of these instead
+myBar.Set('chart.tooltips', ['56', (67).toString(), String(53)]);</span>
+</pre>
+
+ <a name="annotations"></a>
+ <h4>Annotations aren't saved when running locally in Mozilla Firefox</h4>
+
+ <p>
+ The solution here is to run the graphs using a web server. At this time (March 2010) only Safari, Chrome and Opera
+ support saving annotations when running locally.
+ </p>
+
+ <a name="missing.text"></a>
+ <h4>Missing text in Google Chrome</h4>
+
+ <p>
+ Since one of the Chrome 4 dev releases there has been an issue with Google Chrome 4 and 5, asynchronous processing and not rendering
+ graph labels. This has been remedied by simply not using asynchronous processing. Because of the tag placement on the front page,
+ the effect shouldn't be apparent. Other browsers (eg Firefox, Safari, Opera, MSIE) are fine.
+ </p>
+
+ <a name="firefox.tooltips.clipboard"></a>
+ <h4>Firefox, tooltips and the clipboard</h4>
+
+ <p>
+ Firefox, tooltips and using the clipboard is a little convoluted. To copy the text in a tooltip you must do the following:
+ </p>
+
+ <ol>
+ <li style="margin-top: 0">Select the text you want with the mouse.</li>
+ <li style="margin-top: 0">Press CTRL+C (it may be a different key combination if you're not using Windows) to copy the text to the clipboard.</li>
+ </ol>
+
+ <p>
+ <b>Note:</b> Recent versions of Firefox 4 (from beta 6 onwards) appear to work as expected, and you can copy text with the mouse as normal.
+ </p>
+
+ <h4>Shadows in Google Chrome and the line chart</h4>
+
+ <p>
+ Shadows in recent versions of Google Chrome are somewhat broken. Firefox, MSIE, Opera and Safari are fine. The reason for this
+ error is a combination of factors it seems - shadow blurring and line width. Fixes have been added to allow shadow blurring and
+ a 1 pixel linewidth, though some graph types may still be affected.

+
+ <h1>RGraph: HTML5 canvas graph library - Examples of keys</h1>
+
+ <div style="float: right; display: inline-block; width: 650px">
+ <canvas id="myLine" width="600" height="250" style="float: right">[No canvas support]</canvas>
+ <canvas id="myPie" width="450" height="250" style="float: right">[No canvas support]</canvas>
+ </div>
+
+ <p>
+ As of 4th December 2010 the code that produces the keys has been rewritten. There are two variants of keys available,
+ a horizontal one designed to sit in the gutter, and a vertical one that is designed to sit on top of (ie over) the graph.
+ </p>
+
+ <p>
+ The actual positioning is now configurable though, so you could have a horizontal key and position it to sit on top
+ of the chart.
+ </p>
+
+ <h4>Key properties</h4>
+
+ <p>
+ The available key properties and their defaults are listed below (some graph types have slightly different defaults to
+ suit):
+ </p>
+
+
+ <ul>
+ <li>chart.key (<i>[] (An empty array)</i>)</li>
+ <li>chart.key.position (<i>graph</i>)</li>
+ <li>chart.key.position.gutter.boxed (<i>true</i>)</li>
+ <li>chart.key.position.x (<i>null</i>)</li>
+ <li>chart.key.position.y (<i>null</i>)</li>
+ <li>chart.key.shadow (<i>false</i>)</li>
+ <li>chart.key.shadow.offsetx (<i>2</i>)</li>
+ <li>chart.key.shadow.offsety (<i>2</i>)</li>
+ <li>chart.key.shadow.color (<i>#666</i>)</li>
+ <li>chart.key.shadow.blur (<i>3</i>)</li>
+ <li>chart.key.color.shape (<i>square</i>)</li>
+ <li>chart.key.background (<i>white</i>)</li>
+ <li>chart.key.rounded (<i>true</i>)</li>
+ <li>chart.key.text.size (<i>10</i>)</li>
+ </ul>

+ <b>Do I need to buy a license?</b><br /><br />
+ For commercial/business use yes, you need a license to use RGraph. RGraph is not free software.
+ For non-commercial use (eg personal, charity and educational), RGraph is freely usable and you
+ don't need to buy a license though. You can read the license itself
+ <a href="#licensetext">here</a>.

+ <a name="howmuch"></a>
+ <p> </p>
+
+
+ <b>How much is a license?</b><br /><br />
+ A license is a one-time fee of <b>£49</b> (UK pounds). That's roughly $70 (US dollars) at
+ the time of writing.
+
+
+ <a name="read"></a>
+ <p> </p>
+
+ <b>Where can I read the license?</b><br /><br />
+ The license is further down this page.
+
+ <br /><br />
+
+ <a name="cover"></a>
+ <p> </p>
+ <b>What does the license cover?</b><br /><br />
+ The RGraph license covers RGraph as a whole. Excepting ExCanvas, all code that you find in the RGraph archive is
+ covered by the RGraph license. The license also covers code that I've written that is available from <a href="http://www.phpguru.org" target="_blank">phpguru.org</a>.
+ This is a mainly
+ PHP focused website, but also plays host to a fair amount of Javascript too. So if your development language of choice is not PHP,
+ you may still find something of use there.<br /><br />

+ <a name="chart.tooltips.coords.adjust"></a>
+<b>chart.tooltips.coords.adjust</b><br />
+ If you translate() before drawing your graph to reduce wasted space, the coords used for tooltips may need adjusting by how much you translate() by. This setting is how to do it. It should be an array of the X/Y adjustments. There's an example of this on the <a href="misc.html#reducing.white.space">misc documentation</a> page.<br /><i>Default: [0,0]</i><br /><br />

+ <h2>Methods</h2>
+
+ <a href="getPoint"></a>
+ <b>obj.getPoint()</b><br /><br />
+ This method makes it easier to get hold of which point on the Line chart has been hovered over. It returns an array of:
+
+ <ul>
+ <li>The graph object</li>
+ <li>The X coordinate</li>
+ <li>The Y coordinate</li>
+ <li>The numerical index of the point. This corresponds (for example) to the tooltips array, and the coordinates array</li>
+ </ul>
+
+ An example usage is:
+
+ <pre class="code">
+<canvas id="cvs" width="600" height="300">[No canvas support]</canvas>
+
+<script src="RGraph.common.core.js"></script>
+<script src="RGraph.line.js"></script>

+ myGraph.Set('chart.labels', ['Fred','John','Kev','Lou','Pete']);
+ myGraph.Draw();
+
+
+ RGraph.Register(myGraph);

+
+ <a name="combining.line.bar"></a>
+ <h2>Combining the Line and Bar charts</h2>
+
+ <p>
+ You can combine the Bar and Line charts with a bit of magic. It's actually quite easy to do. <a href="combine.html">Find out more here</a>.
+ In the same vein, you can have Y axes on both the left and right.
+ </p>
+
+
+ <a name="alternative.colors"></a>
+ <h2>Alternative colors</h2>
+
+ <p>
+ Instead of a string stipulating the color, each element of the colors array can itself be a two element array,
+ stipulating the up color, and the down color. To use alternating colors you must also stipulate the alternate property:
+ </p>
+
+
+ <pre class="code">
+myLine.Set('chart.colors.alternate', true);
+myLine.Set('chart.colors', ['red', ['blue', 'yellow'], 'green]);
+</pre>
+
+ <a name="custom.tickmarks"></a>
+ <h2>Custom tickmarks</h2>
+ <p>
+ If none of the available tickmark styles are suitable, you can instead specify a function object that draws the tickmark,
+ enabling you to draw the tickmark yourself. For example:
+ </p>
+
+ <pre class="code">
+<script>
+ line.Set('chart.tickmarks', myTick);
+
+ /**
+ * The function that is called once per tickmark, to draw it
+ *
+ * @param object obj The graph object
+ * @param array data The entire line data
+ * @param number value The individual points value
+ * @param number index The current index, in the data array
+ * @param number x The X coordinate
+ * @param number y The Y coordinate
+ * @param string color The color of the line
+ * @param number prevX The previous X coordinate
+ * @param number prevY The previous Y coordinate
+ */
+ function myTick (obj, data, value, index, x, y, color, prevX, prevY)
+ {
+ // Draw your custom tick here
+ }
+</script>

+ <br /> <br /> <br />
+ <h4>Canvas fallback content and visually impaired users</h4>
+
+ <p>
+ When using the canvas element you should be aware of the accessibility of your graphs, for example where vision limited users are
+ concerned. Screen readers, for example, may not be able to convert a graph into something that is reasonable, so you should
+ consider
+ doing this yourself, possibly using the canvas fallback content (ie the content in between the canvas tags). A possible example
+ would be to put a table of data inside the canvas tag that the graph on the canvas represents. Doing this goes a long way
+ towards making the data available to everyone. You might also wish to consider using the <a href="zoom.html">full canvas
+ zoom</a> or the <a href="resizing.html">resizing feature</a> to enable people to enlarge the graph.
+ </p>
+
+ <a name="limits"></a>
+ <br /> <br /> <br />
+ <h4>Upper and lower limits for horizontal bars</h4>
+
+ <p>
+ If you don't wish to specify an upper or lower limit for horizontal bars, and you just want them to extend to the upper or lower
+ limits of the graph, whatever they may be, you can specify null for the value determining how far they extend. For cases where
+ the X axis is in the middle and you're specifying a negative start value, or you want the bar to extend all the way to the
+ bottom, you can simply specify an arbitrary length (eg -999999). Eg:
+ </p>
+
+ <pre class="code">myBar.Set('chart.background.hbars', [[0, null, 'green'], [0,-999999,'red']]);</pre>
+
+ <a name="canvas.width.height"></a>
+ <br /> <br /> <br />
+ <h4>Setting the canvas width and height</h4>
+
+ <p>
+ To set the canvas width and height you must use the HTML width/height attributes and NOT CSS. If you do use CSS, the canvas
+ will be scaled, and not enlarged, to fit the new width/height. Eg:
+ </p>
+
+ <pre class="code"><canvas id="myCanvas" width="200" height="100">[No canvas support]<canvas></pre>
+
+ <p />
+
+ <a name="older.browsers"></a>
+ <br /> <br /> <br />
+ <h4>RGraph and older browsers</h4>
+
+ <p>
+ Older versions of browsers are supported (assuming they have canvas support), however, if they don't support the canvas text
+ or shadow APIs these will naturally be unavailable. The graphs will still be drawn, though without shadows or text.
+ </p>
+
+ <a name="msie"></a>
+ <br /> <br /> <br />
+ <h4>RGraph and Microsoft Internet Explorer</h4>
+
+ <p>
+ You can now use RGraph with Internet Explorer 8 in conjunction with ExCanvas, (which brings a degree of <canvas> support to MSIE).
+ Bear in mind though that shadows are not available and thus are simulated. Microsoft Internet Explorer 9 has native <canvas>
+ support. You can see some screenshots of it <a href="http://groups.google.com/group/rgraph/browse_thread/thread/3cce2cd655918b0c#" target="_blank">here</a>.
+ </p>
+
+ <a name="debugging"></a>
+ <br /> <br /> <br />
+ <h4>Debugging tips</h4>
+
+ <p>
+ If you're having a hard time debugging your graph, try these:
+ </p>
+
+ <ul>
+ <li>Ensure you have only one graph on the page</li>
+ <li>Make sure you have disabled your web browsers cache (the Firefox <a href="https://addons.mozilla.org/en-US/firefox/addon/60" target="_blank">Web Developer toolbar</a> can do this for Firefox)</li>
+ <li>Try using <a href="http://www.getfirebug.com" target="_blank">Firebug</a> (for Firefox) or the Webkit developer tools (for Google Chrome and Safari)</li>
+ <li>Reduce the page to the bare minimum.</li>
+ <li>Start with a very basic graph and build it up slowly.</li>
+ </ul>
+
+
+
+ <a name="inspecting"></a>
+ <br /> <br /> <br />
+ <h4>Inspecting an RGraph graph</h4>
+
+ <p>
+ To help when debugging your RGraph graphs and canvas elements, you can use you browsers built in debugging tools.
+ An example is the WebKit developer tools which are available in Google Chrome and Apple Safari. There is a screenshot
+ of these tools (in docked mode) <a href="../images/introspection.png" target="_blank"><b>here</b></a>. To view these
+ tools in Google Chrome press CTRL+SHIFT+J. Inspect the canvas, and then the associated object can be found via
+ the <i>__object__</i> property.
+ </p>
+
+
+ <a name="context.menus"></a>
+ <br /> <br /> <br />
+ <h4>Double click context menus</h4>
+
+ <p>
+ Windows Opera, Windows Safari, Mac Safari and Mac Firefox all attach the context menu to the double click event (left mouse button),
+ not the right, in order to make it more reliable.
+ </p>
+
+
+ <a name="event.handlers"></a>
+ <br /> <br /> <br />
+ <h4>Adding your own event handlers</h4>
+
+ <p>
+ Because each RGraph object exposes the canvas element (the same as what you get from <i>document.getElementById()</i>),
+ you can use normal procedures to add your own event handlers. Eg If you wanted to add your own onclick handler you could
+ do this:
+ </p>
+
+ <pre class="code">
+<script>
+ var myBar = new RGraph.Bar('cvs', [7,4,2,6,3,4,8]);
+ myBar.Draw();
+
+ myBar.canvas.onclick = function ()
+ {
+ }
+</script>
+</pre>
+ <p>
+ But what if, for example, you're using an RGraph feature which
+ uses the event handler that you need? In this case you can use the standard DOM method <i>addEventListener()</i>. This will add
+ your new event handler without replacing any existing one (ie the one installed by RGraph). For example:
+ </p>
+
+ <pre class="code">
+<script>
+ var myBar = new RGraph.Bar('cvs', [7,4,2,6,3,4,8]);
+ myBar.Draw();
+
+ function myFunc ()
+ {
+ }
+
+ myBar.canvas.addEventListener('click', myFunc, false)
+</script>
+</pre>
+
+
+ <a name="crlf"></a>
+ <br /> <br /> <br />
+ <h4>Carriage returns and newlines in labels</h4>
+
+ <p>
+ You can put carriage returns in your labels by using the string <i>\r\n</i>. This means your labels will span multiple lines.
+ Like so:
+ </p>
+
+ <pre class="code">myBar.Set('chart.labels', 'John\r\n(Winner!)', ...)</pre>
+
+
+ <a name="tradar"></a>
+ <br /> <br /> <br />
+ <h4>Why is the Traditional Radar chart so called?</h4>
+
+ <p>
+ Historical reasons. There used to be two Radar charts in RGraph - the TRadar and an older one called the Pseudo radar chart.
+ The Pseudo Radar chart was converted into the Rose chart. Renaming the TRadar will only cause problems and there's no pressing
+ reason to do so, so for the moment it remains the TRadar chart.
+ </p>
+
+
+ <a name="character.set"></a>
+ <br /> <br /> <br />
+ <h4>Character set issues</h4>
+
+ <p>
+ If you're seeing strange, unrecognised characters in your text labels or titles, you may need to specify the correct
+ character set that the browser should use. In PHP you can do this with the <i>header()</i> function (which, as the
+ name suggests, sends a HTTP header):
+ </p>
+
+ <pre class="code"><?php
+ header("Content-Type: text/html; charset=ISO-8859-1");
+?></pre>
+
+ <p>
+ If you use Apache, you could use the <i>header</i> directive, though this may be overridden by other directives,
+ eg <i>AddDefaultCharset</i>.
+ </p>
+
+ <a name="rgraph.identify"></a>
+ <br /> <br /> <br />
+ <h4>How to identify an RGraph object</h4>
+
+ <p>
+ Because identity can sometimes be a tricky affair, there are a few RGraph properties that you can use to check whether an object
+ is an RGraph object:
+ </p>
+
+ <ul>
+ <li><i>obj.isRGraph</i> - This is a boolean that you can use to clearly identify an RGraph object.</li>
+ <li><i>obj.type</i> - This identifies the type of an RGraph object. It is a string which contains a one word description of the objects graph type, eg bar/line/pie.</li>
+ </ul>

+ </script>
+
+ A static Y axis is useful if you have a wide chart but limited space. Whilst not part of the RGraph libraries itself, it can be
+ achieved with a little HTML, like the graph shown. The HTML and the script to achieve this is documented in the source
+ of this page. It involves placing an extra canvas above the graph with the Y axis drawn on it. This canvas doesn't
+ move when the main canvas scrolls left and right.
+
+ <p />
+
+ <b>Note:</b> Because Firefox doesn't support the event.offsetX and event.offsetY properties, and they have to be simulated,
+ scrolling and tooltips in this case and this browser doesn't work.

+ If the labels that you have require a large gutter you can reduce the amount of wasted space by using the standard 2D
+ context method <i>translate()</i>. This effectively moves the coordinate system so that (0,0) is no longer in the top
+ left corner, but whereever you put it. For example if you translate by (15,-15), the origin will then be 15 pixels right and
+ 15 pixels up compared to where it was.
+ </p>
+
+ <p>
+ Because the coordinate system is being changed things that rely on coordinates, eg tooltips, will be affected. For this reason
+ there is the property <i>chart.tooltips.coords.adjust</i> which you can use to tell RGraph that you've translated and the
+ tooltip coordinates will be adjusted appropriately.
+ </p>

+ <a name="introduction"></a>
+ <h4>Introduction</h4>
+
+ <p>
+ As of December 2009 RGraph now works partially with Internet Explorer without Google Chrome Frame.
+ Graphs are rendered as VML. You are still recommended to use
+ <a href="http://code.google.com/chrome/chromeframe/">Google Chrome Frame</a> to get the best results.
+ The interactive features are unlikely to work correctly. RGraph only works with Microsoft
+ Internet Explorer 8.
+ </p>
+
+ <p>
+ Thanks go to everyone involved with the <a href="http://code.google.com/p/explorercanvas/" target="_blank" rel="nofollow">ExCanvas project</a> for providing the ExCanvas library.
+ </p>
+
+ <a name="getting"></a>
+ <h4>Getting hold of ExCanvas</h4>
+
+ <p>
+ Google ExCanvas is distributed with RGraph in the "excanvas" directory. There is a minified gzip compressed version, along
+ with the original.
+ </p>
+
+ <a name="caveats"></a>
+ <h4>Caveats</h4>
+
+ <ul>
+ <li>The interactive features of RGraph are unlikely to work correctly with MSIE 8.</li>
+ <li>Shadows are now available (on some graph types), albeit without blurring.</li>
+ <li>You must reference the Javascript libraries in the documents <head>.</li>
+ <li>You must use the window.onload event to create your graph.</li>
+ <li>
+ Inside the window.onload function your graph must be created as a <i>local</i> variable (ie you must use the <i>var</i> keyword). Eg:
+ <pre class="code">
+<script>
+ window.onload = function ()
+ {
+ <span style="color: green">var</span> myGraph = new RGraph.Bar('myCanvas', [1,9,8,7,3,4,8,4,9,5,7,8]);
+ myGraph.Set('chart.labels', ['Jan','Feb','Mar','Apr','May','Jun','Jul','Aug','Sep','Oct','Nov','Dec']);
+ myGraph.Draw();
+ }
+</script>
+</pre>
+ </li>
+ <li>If your page is large, there may be a slight pause before the window.onload event fires and thus creates the graph.</li>
+ <li>Changing the font that text is shown in is not available.</li>
+ </ul>
+
+ <a name="frame"></a>
+ <h4>Google Chrome Frame</h4>
+ <p>
+ Instead of ExCanvas you can also use Google Chrome Frame. This basically turns Internet Explorer into Google Chrome, and fully
+ supports RGraph. Since it involves a plugin installation, this is a better option if you can fully influence the users PC. If you
+ can fully influence the users PC however, a better option might be to simply use one of the browsers with native
+ support.
+ </p>
+
+
+ <br />
+
+
+ <a name="dynamic.canvas"></a>
+ <h4>Using a dynamically created canvas</h4>
+ <p>
+ If you're creating your canvas dynamically there is an extra step that you must perform to allow it to be recognised by
+ ExCanvas:
+ </p>
+
+ <pre class="code">
+var canvas = document.createElement('CANVAS');
+ canvas.id = 'cvs';
+ canvas.width = 600;
+ canvas.height = 250;
+ canvas.style.border = '1px dashed black';
+document.body.appendChild(canvas);
+
+<span style="color: green">G_vmlCanvasManager.initElement(canvas);</span>
+</pre>
+
+
+
+ <br />
+ <br />
+ <br />
+
+ <!-- This is the ModdalDialog -->
+ <div id="myDialog" style="display: none">
+ <div style="text-align: center; font-family: Arial">
+ <h4>Please wait...</h4>
+ <span style="font-size: 8pt">(Nothing is going to happen, this is simply an example <a href="" onclick="ModalDialog.Close(); return false">Close</a>)</span>
+ </div>
+ </div>
+</body>

+
+ <b>RGraph.getSegment()</b><br /><br />
+
+ RGraph.getSegment() makes it easy to determine which segment of the Pie chart was clicked on. It provides:
+
+ <ul>
+ <li>Originating X coordinate</li>
+ <li>Originating Y coordinate</li>
+ <li>The radius of the segment</li>
+ <li>The starting angle (in degrees)</li>
+ <li>The ending angle (in degrees)</li>
+ </ul>

+ RGraph provides an easy way to get a PNG image of your graph. This allows you to
+ easily save the image locally to use in (for example) a document, spreadsheet or presentation.
+ </p>
+
+ <p>
+ Originally, the function was designed to be used with a context menu, so it is located in the <i>RGraph.common.context.js</i>.
+ Now though, you do not have to use the function with a context menu, and can instead pass in the canvas as the optional argument. There's an
+ example of its usage on the first <a href="../examples/tradar.html">Tradar example</a href>.
+ </p>
+
+ <br clear="all" />
+
+ <p>Include the context menu code:</p>
+ <pre class="code"><script src="../libraries/RGraph.common.context.js" ></script></pre>
+
+ <p>Add the context menu:</p>
+ <pre class="code">
+myGraph.Set('chart.contextmenu', [
+ <span style="color: green">['Get PNG', RGraph.showPNG]</span>,
+ null,
+ ['Cancel', function () {}]
+ ]);</pre>
+
+ <h4>Using the function without a context menu</h4>
+
+ <p>
+ If you want to use the function with a piece of text (or an image) as the "link", optionally positioned over the canvas, you can pass
+ the canvas into the function as an argument, along with the event object.
+ </p>

+ RGraph has the facility to allow you to resize your graphs. This is new as of 10th April 2010. Because of the
+ numerous events it has to install code on, it is unlikely to work with other dynamic features. The context
+ menu does though, and now that tooltips use DOM2 events, so do they. It can be useful if you are,
+ for example, doing a presentation and need to enlarge the graph.
+ </p>
+
+ <p>
+ All you need to do to enable it is set <i>chart.resizable</i> to true. There are certain caveats that you should be aware of though:
+ </p>
+
+ <br clear="all" />
+
+ <ul>
+ <li>
+ Graphs can only be enlarged down and to the right, so you will get better results if your graph is not placed at the
+ right of the page.
+ </li>
+
+ <li>
+ The minimum you can resize your graphs to is 50% of the original graph width/height.
+ </li>
+
+ <li>
+ <b>Note:</b> Resizing can change the layout of your page (reflows). As such you will need to be careful when laying out your
+ page, and you may need to experiment with things like CSS float:, width, height etc so that the effect is either not apparent
+ or is minimal.
+ </li>
+
+ <li>
+ If your canvas is nested within a table, resizing can result in very minor (1-2px for example) positioning changes. These
+ can be mitigated by turning off table borders, setting the cellspacing to 0 and also setting the cellpadding to 0.
+ </li>
+ </ul>

+ As you can see each mark on the Scatter chart is made by supplying an array of up to 4 elements:
+ </p>
+
+ <ul>
+ <li>The X value (required)</li>
+ <li>The Y value (required)</li>
+ <li>The color (optional)</li>
+ <li>The tooltip for this mark (optional)</li>
+ </ul>
+
+ <p>
+ If you wish to specify a tooltip, but not a color (ie use the default color instead), you can pass null instead of a color.

+ <h2>Box plots</h2>
+
+ <p>
+ Instead of a single Y value, you have the ability to specify an array of 5, 6, 7 or 8 values, which will be used to make a box plot.
+ The <a href="../examples/scatter.html#boxplots">example page shows a box plot</a>. These values are (in order):
+
+ <ul>
+ <li>Lower whisker</li>
+ <li>Bottom of box</li>
+ <li>Middle value (which isn't necessarily in the center of the box - this depends on your data)</li>
+ <li>Top of box</li>
+ <li>Upper whisker</li>
+ <li>Upper color (optional)</li>
+ <li>Lower color (optional)</li>
+ <li>Width (optional)</li>
+ </ul>
+
+ <pre class="code">
+<script>
+ scatter8 = new RGraph.Scatter('scatter8', [
+ [10,<span style="color: green">[1,1,16,24,24, 'red', 'green']</span>],
+ [105,<span style="color: green">[5,10,15,25,25, 'red', 'green']</span>],
+ [125,<span style="color: green">[10,15,25,35,45, 'red', 'green']</span>],
+ [325,<span style="color: green">[10,15,25,35,45, 'red', 'green', 30]</span>]
+ ]);
+ scatter8.Set('chart.title', 'An example of a boxplot');
+ scatter8.Set('chart.labels', ['Q1', 'Q2', 'Q3', 'Q4']);
+ scatter8.Set('chart.xmax', 365);
+ scatter8.Set('chart.ymax', 50);
+ scatter8.Set('chart.boxplot.width', 12); // The default width
+ scatter8.Draw();
+</script>
+</pre>
+ </p>
+
+
+ <a name="labelpoints"></a>
+ <h2>Specific points for labels on the X axis</h2>
+
+ <p>
+ Instead of a simple string which is used as the label, each entry of the chart.labels array can be a two element array
+ consisting of the label, and the X value that the label should be placed at. For example:
+ </p>
+
+ <pre class="code">
+scatter.Set('chart.labels', [
+ ['Quarter 1', 0],
+ ['Quarter 2', 90],
+ ['Quarter 3', 181],
+ ['Quarter 4', 273]
+ ]);
+</pre>
+
+
+
+ <a name="custom.tickmarks"></a>
+ <h2>Custom tickmarks</h2>
+
+ <p>
+ If none of the available tickmark styles are suitable, you can instead specify a function object that draws the tickmark,
+ enabling you to draw the tickmark yourself. For example:
+ </p>
+
+ <pre class="code">
+<script>
+ line.Set('chart.tickmarks', myTick);
+
+ /**
+ * The function that is called once per tickmark, to draw it
+ *
+ * @param object obj The graph object
+ * @param object data The graph data
+ * @param number x The X coordinate
+ * @param number y The Y coordinate
+ * @param number xVal The X value
+ * @param number yVal The Y value
+ * @param number xMax The maximum X scale value
+ * @param number xMax The maximum Y scale value
+ * @param string color The color of the tickmark
+ */
+ function myTick (obj, data, x, y, xVal, yVal, xMax, yMax, color)
+ {
+ // Draw your custom tick here
+ }
+</script>
+</pre>
+
+ <a name="colors"></a>
+ <h2>Note about colors and the key</h2>
+
+ <p>
+ If you're using a key you may need to set <i>chart.line.colors</i> to allow it to use the correct colors. For example:
+ </p>
+
+ <pre class="code">myObj.Set('chart.line.colors', ['red','green','blue']);</pre>

+ <h4>Introduction</h4>
+
+ <p>
+ Tooltips are a very effective and straight forward way to extend your graphs and add more information to them, without overloading
+ the user.
+ </p>
+
+ <a name="hold"></a>
+ <h4>What can they hold?</h4>
+
+ <p>
+ At the base level, tooltips are DIVs, so they can hold a multitude of HTML - images, videos etc. See <a href="#graphs">below</a>
+ for information on showing graphs in tooltips.
+ </p>
+
+ <a name="how"></a>
+ <h4>How can I specify them?</h4>
+
+ <p>
+ You can specify them by including the tooltips code and then using the <i>chart.tooltips</i> property. For example:
+ </p>
+
+ <ol>
+ <li>
+ Include the RGraph libraries.
+ <pre class="code">
+<script src="RGraph.common.core.js"></script>
+<script src="RGraph.common.tooltips.js"></script>
+<script src="RGraph.line.js"></script>
+</pre>
+ </li>
+
+ <li>
+ Define your graph and set the tooltips property.
+ <pre class="code">
+<script>
+ window.onload = function ()
+ {
+ var line = new RGraph.Line('cvs', [64,34,26,35,51,24]);
+ <span style="color: green">line.Set('chart.tooltips', ['<b>Winner!</b><br />John', 'Fred', 'Jane', 'Lou', 'Pete', 'Kev']);</span>
+ line.Set('chart.tooltips.effect', 'expand');
+ line.Set('chart.gutter', 30);
+ line.Set('chart.hmargin', 10);
+ line.Set('chart.linewidth', 2);
+ line.Set('chart.shadow', true);
+ line.Set('chart.shadow.offsetx', 0);
+ line.Set('chart.shadow.offsety', 0);
+ line.Set('chart.shadow.color', 'green');
+ line.Set('chart.shadow.blur', 25);
+ line.Set('chart.colors', ['green']);
+ line.Set('chart.tickmarks', 'circle');
+ line.Set('chart.labels', ['John', 'Fred', 'Jane', 'Lou', 'Pete', 'Kev']);
+ line.Draw();
+ }
+</script>
+</pre>
+ </li>
+ </ol>
+
+ <a name="what"></a>
+ <h4>What can I specify?</h4>
+
+ <p>
+ The tooltips that you specify are usually strings (which can contain HTML). They can however also be functions which are called when they're about
+ to be displayed. The function should return the text that is used as the tooltip. You have the option to either specify
+ one function per data point, or just one function for all of the tooltips. You can mix functions and strings if you wish.
+ These functions are passed the numerical, zero-indexed tooltip index and the return value is used as the tooltip
+ text. So to summarise:
+ </p>
+
+ <ul>
+ <li>
+ An array of strings. The string is used as the tooltip. Eg:
+ <pre class="code">myGraph.Set('chart.tooltips', ['John', 'Fred', 'Lou']);</pre>
+ </li>
+
+ <li>
+ An array of function objects. Each function is called and should return the text to be used. Eg:
+ <pre class="code">myGraph.Set('chart.tooltips', [getJohnTooltip, getFredTooltip, getLouTooltip]);</pre>
+ </li>
+
+ <li>
+ A single function object. This is probably the most useful. This function is called whenever a tooltip
+ is about to be displayed, and passed the numerical, zero-indexed tooltip index of the graph. The function should
+ return the text to be used as the tooltip. Note that the function you specify is called <i>before</i>
+ the tooltip DIV has been created, so you cannot access it. If you wish to customise the appearance
+ of the tooltip, you can use either the tooltip <a href="css.html">CSS class</a> or a call to <i>setTimeout()</i>. Eg:
+ <pre class="code">myGraph.Set('chart.tooltips', getTooltip);</pre>
+ </li>
+
+ <li>
+ An array of DIV ids. This will make working with large tooltips easier. You basically specify the id of a DIV whose
+ .innerHTML is then used as the tooltip. Only the contents of the DIV are used, not the DIV itself, so you can hide
+ the DIV by setting its <i>display</i> CSS value to <i>none</i>. An example of this in action is the
+ <a href="../examples/line.html">first line chart</a>. For example:
+
+ <pre class="code">myBar.Set('chart.tooltips', ['id:myDiv', ...])</pre>
+ </li>
+ </ul>
+
+ <a name="graphs"></a>
+ <h4>Can I show graphs in tooltips?</h4>
+
+ <canvas style="float: right" id="cvs2" width="600" height="250">[No canvas support]</canvas>
+
+ <p>
+ You can, and with the custom event support that RGraph has (as of 10th July 2010), it's reasonably easy. Simply attach your function that
+ creates the graph to the <i>ontooltip</i> event. This allows the tooltip HTML to be created and added to the page
+ so that the code that creates the graph can run. The sequence is:
+ </p>
+
+ <ol>
+ <li style="margin-top: 0">Specify the HTML for the tooltip as normal (including the <canvas> tag).</li>
+ <li style="margin-top: 0">Use the <i>ontooltip</i> RGraph event so that a function is called when a tooltip is shown.</li>
+ <li style="margin-top: 0">This function should subsequently create the graph.</li>
+ </ol>
+
+ <p>
+ The tooltip DIV is to be found in the RGraph registry - <i>RGraph.Registry.Get('chart.tooltip')</i>. And if you want it the
+ numerical zero indexed count of the tooltip is to be found in the <i>__index__</i> property:
+ <i>RGraph.Registry.Get('chart.tooltip').__index__</i>
+ </p>
+
+ <pre class="code">
+<script src="RGraph.common.core.js" ></script>

+ If you want to see more source code, simply view the source of this page and look at the code that creates the bar chart.
+ </p>
+
+ <br clear="all" />
+
+ <a name="customise"></a>
+ <h4>Can I customise the appearance of tooltips?</h4>
+
+ <p>
+ Yes. You can either use the default CSS class <i>RGraph_tooltip</i>, or you can specify a specific CSS class that a
+ graphs tooltips should use with the property <i>chart.tooltips.css.class</i>. The two graphs on this page have
+ different looking tooltips by using this method - the line graph uses the default look, whilst the bar chart
+ overrides the CSS class name and sets it to <i>bar_chart_tooltips_css</i>. For example:
+ </p>
+
+ <pre class="code">bar.Set('chart.tooltips.css.class', 'bar_chart_tooltips_css');</pre>
+
+ <pre class="code">
+<style>
+ .bar_chart_tooltips_css {
+ background-color: white ! important;
+ border: 2px solid black ! important;
+ padding: 3px;
+ }
+</style>
+</pre>
+
+ <p>
+ You can read more about RGraph CSS classes <a href="css.html">here</a>.
+ </p>
+
+ <a name="effects"></a>
+ <h4>What tooltip effects are available?</h4>
+
+ <p>
+ These effects are available to you:
+ </p>
+
+ <ul>
+ <li>fade</li>
+ <li>expand</li>
+ <li>contract</li>
+ <li>snap</li>
+ <li>none</li>
+ </ul>
+
+ <p>
+ All of them are as their names imply. <i>fade</i> is a straight forward fade in effect, <i>expand</i> is another effect
+ which expands outward from the center of the tooltip, <i>contract</i> is like the <i>expand</i> effect but in reverse, <i>snap</i> is an effect which can be used in a limited set of circumstances
+ and "snaps" to the current mouse position and <i>none</i> is simply no effect at all. The default effect used
+ by all graph types is <i>fade</i>. Note: If you're showing canvases in your tooltips then the <i>expand</i>, <i>contract</i> and <i>snap</i>
+ effects will not work - you must use <i>fade</i> or <i>none</i>.
+ </p>
+
+ <p>
+ <b>Note:</b> The snap effect is only available to graph types where the tooltip is triggered using the onmousemove event.
+ Currently this means the <i>Line chart</i>, <i>Rscatter graph</i>, <i>Scatter graph</i> and Tradar chart. It can also
+ be negatively effected when using multiple graphs on one page.
+ </p>
+
+
+ <a name="firefox"></a>
+ <h4>Tooltips, the clipboard and Firefox</h4>
+
+ <p>
+ If you're using Firefox, there's a note about tooltips and the clipboard (ie copying text) on the <a href="issues.html">issues page</a>.
+ </p>
+
+ <a name="override"></a>
+ <h4>Can I override the tooltip function?</h4>
+
+ <p>
+ You can by stipulating <i>chart.tooltips.override</i>. This should be a function object that handles everything with regard
+ to showing the tooltip. Highlighting the graph is still done for you - the override function is only concerned with showing
+ the tooltip. The override function is passed these arguments:
+ </p>
+
+ <ul>
+ <li>canvas - The HTML canvas element, the same as what you get from document.getElementById()</li>
+ <li>text - The tooltip text (id:xxx strings are NOT expanded)</li>
+ <li>x - The X coordinate in relation to the entire page</li>
+ <li>y - The Y coordinate in relation to the entire page</li>
+ <li>index - The numerical index of the tooltip in the original tooltip array</li>
+ </ul>
+
+ <p>
+ <b>Note:</b> Although "id:xxx" strings are not expanded for you, you can easily do this yourself by using the
+ <i>RGraph.getTooltipText('id:xxx')</i> function.
+ </p>
+
+ <pre class="code">
+<script>
+ function tooltip_override (canvas, text, x, y, idx)
+ {
+ alert('In tooltip override function...');
+ }
+ myObj.Set('chart.tooltips.override', tooltip_override);
+</script>

+ <b>Making the zoom circular</b><br /><br />
+ <img src="../images/border-radius.png" width="171" height="159" alt="A circular zoom window" style="float: right; border: 1px gray solid" />
+ It is possible to make the zoom in area mode circular by utilising the <i>border-radius</i> CSS property. Currently support for
+ this is limited to FireFox 4b7+, so it's not part of the main RGraph software. The CSS ncessary to achieve this is
+ thus:
+ </p>
+
+ <pre class="code" style="width: 700px" />
+<style>
+ .RGraph_zoom_window {
+ border-radius: 50px ! important;
+ }
+</style>
+</pre>
+
+ This a graph demonstrating this technique <a href="zoom_thumbnail.html">here</a>. Note that browser support for this technique is limited.
+
+ <br clear="all" />
+
+
+ <a name="area"></a>
+ <h2>Area mode</h2>
+
+ <canvas id="myc3" width="600" height="250" style="float: right">[No canvas support]</canvas>
+
+ <p>
+ Another type of zoom available is <i>area</i>. This is somewhat similar to thumbnail, but allows you to draw a rectangle around
+ the specific area that you want to zoom.
+ </p>
+
+ <p>
+ Again, this uses some common zoom properties, such as <i>chart.zoom.factor</i>.
+ </p>
+
+ <p>
+ Once visible, you can drag the zoomed area around with the left mouse button (a left drag), and drag the zoomed canvas around
+ within the zoom by using the right mouse button (a right-drag). And a double click will expand the zoomed area to cover the
+ whole canvas.
+ </p>
+
+ <br clear="all" />
+
+ <pre class="code">
+<script>
+ var myLine = new RGraph.Line('myc3', [15,30,62,26,46,86,48,51,51,35,32, 35]);
+ myLine.Set('chart.zoom.mode', 'area');

+ The bar chart is probably one of the most widely used of charts, and also one of the most versatile. It's defined as a chart with
+ rectangular bars with lengths proportional to the values they represent. The bar chart can be used to represent two
+ or more values. With grouped and stacked bar charts, you can visualise two or more sets of data. For example two years
+ worth of sales figures. Doing this you will be able to easily see differences, for example a better year when it comes
+ to sales. You can also show negative values by having the X axis in the center, like the examples shown. If you use a
+ grouped or stacked bar chart, a key may be helpful to your users.
+ </p>
+
+ <p>
+ By using the tooltips feature, you can provide more detail about what a particular bar represents. The tooltips in
+ <b>RGraph</b> can contain wide range of HTML, so you can use them to show photos or movies for example.

+ A Gantt chart is used to show scheduling information. It is commonly used in project management but can also be used,
+ for example, to show holiday schedule information. In this case it would be easy to see when someone is unavailable.
+ The Gantt chart can have clickable bars that can be used to provide more detail. It can also show vertical bars
+ that can be used to indicate events, or as in the cases below, can be decorative.
+ </p>
+
+ <p>
+ The chart is made of "units", in this case 365. This represents days in a year. The labels are separate, being equally
+ spaced across the chart. This means you can use more meaningful labels, which are easier to comprehend. As in the
+ example charts.

+ Like the Bar chart, the line chart is one of the most versatile chart types. It is similar, but can indicate chronological
+ data better. The line chart is good if, for example, you want to illustrate sales figures over a year (or any period of
+ time). You'll then be able to easily see whether sales are going up, down or are stagnant. It will also become apparent
+ which months are busier than others. By using a multiple line chart you can add multiple sets of data (eg two or more years
+ of figures) to your chart. You can customise the line chart by stipulating it as being filled, having drop shadows, keys,
+ having the X axis in the centre, different colors, different tickmark styles and tooltips etc.
+ </p>
+
+ <p>
+ The first graph uses external DIVs for the tooltip contents. The DIVs are at the bottom of this page (they're set not to
+ be visible). Using external DIVs for tooltips can make maintenance easier.

+ The Odometer can be used to provide an indication of a particular value. For example you could easily use it to

+ <p>
+ The Pie chart can be used when you need to represent value as part of a whole. It is commonly used to represent percentages,
+ relative magnitudes or relative frequencies. If your intent is to compare a particular value (slice) against the whole of
+ the Pie chart, then it can be quite effective. If however you want to compare two seperate segments, then it can get
+ more difficult. If this is the case, you may want to consider a bar chart for example.
+ </p>
+
+ <p>
+ The colours can of course be customised, as can the borders (using the same color as the background and a line width of
+ about 5 gives the effect of segment separation. The chart can also have a drop shadow if you want one, but this shouldn't
+ be used in conjunction with segment seperation.
+ </p>
+
+ <p>
+ The first pie chart has a fade-in effect. This not part of the RGraph library but is very easy to implement.

+ The Scatter graph uses two variables to plot points and makes it clear where there are congregations. The data points
+ make up the X and Y coordinates. The labels on the X axis are separate from the X units, allowing you to "group" them. For
+ example, like the example, you could set the maxium X value to be 365, but only have four labels. That way you would
+ have a granularity of a day, but the X axis would only have four labels. Like the example.

+<p>
+ RGraph.Text() is a text drawing function that allows vertical and horizontal alignment, and allows you to specify the angle of the
+ text too. The animation is done by a simple gobal variable, setTimeout() and redrawing the entire
+ canvas every frame. Perhaps not the most efficient of methods, but remember that your Javascript will likely be
+ running on computers that have more processing power than
+ some small countries... <a href="javascript: location.href = location.href">Reset the page</a>
+</p>
+
+<p>
+ In a similar vein you could easily make some text that bounces from one side of the screen to the other,
+ hurrah - the return of <marquee>!
+</p>
+
+ <div>
+ More examples can be found on the individual <a href="/examples/index.html">example pages</a>, and a more complete
+ reference to the Text() function can be found in the <a href="../docs/api.html#functions.other">API docs</a>.

+ This is a Progress Bar for showing state. You can show anything with it - use it to show load on your server,
+ or percentage space free on your servers disk drive. You could even incorporate it with some AJAX to retrieve status information
+ from your webserver dynamically, making the Progress Bar realtime. To redraw the progress bar simply call <i>RGraph.Clear()</i>
+ (which clears the canvas) and then call <i>myProgress.Draw()</i> again.

+ <h2>Introduction to RGraph</h2>
+
+ <p>
+ RGraph is a HTML5 canvas graph library. It uses features that became available in HTML5 (specifically, the CANVAS tag)
+ to produce a wide variety of graph types: bar chart, bi-polar chart (also known as an age frequency chart), donut chart,
+ funnel chart, gantt chart, horizontal bar chart, LED display, line graph, meter, odometer, pie chart, progress bar, rose chart,
+ scatter graph and traditional radar chart. RGraph is covered by the <b><a href="#license">RGraph License</a></b>.

+ <p>
+ Being Javascript, RGraph is ideal for use in <b>Chrome extensions</b> and <b>Web Apps</b>. You can download a sample
+ extension <a href="http://www.rgraph.net/RGraph_ChromeExtension_sample.zip"><b>here</b></a>.

+ GNU GENERAL PUBLIC LICENSE\r
+ Version 2, June 1991\r
+\r
+ Copyright (C) 1989, 1991 Free Software Foundation, Inc.\r
+ 51 Franklin St, Fifth Floor, Boston, MA 02110-1301 USA\r
+ Everyone is permitted to copy and distribute verbatim copies\r
+ of this license document, but changing it is not allowed.\r
+\r
+ Preamble\r
+\r
+ The licenses for most software are designed to take away your\r
+freedom to share and change it. By contrast, the GNU General Public\r
+License is intended to guarantee your freedom to share and change free\r
+software--to make sure the software is free for all its users. This\r
+General Public License applies to most of the Free Software\r
+Foundation's software and to any other program whose authors commit to\r
+using it. (Some other Free Software Foundation software is covered by\r
+the GNU Library General Public License instead.) You can apply it to\r
+your programs, too.\r
+\r
+ When we speak of free software, we are referring to freedom, not\r
+price. Our General Public Licenses are designed to make sure that you\r
+have the freedom to distribute copies of free software (and charge for\r
+this service if you wish), that you receive source code or can get it\r
+if you want it, that you can change the software or use pieces of it\r
+in new free programs; and that you know you can do these things.\r
+\r
+ To protect your rights, we need to make restrictions that forbid\r
+anyone to deny you these rights or to ask you to surrender the rights.\r
+These restrictions translate to certain responsibilities for you if you\r
+distribute copies of the software, or if you modify it.\r
+\r
+ For example, if you distribute copies of such a program, whether\r
+gratis or for a fee, you must give the recipients all the rights that\r
+you have. You must make sure that they, too, receive or can get the\r
+source code. And you must show them these terms so they know their\r
+rights.\r
+\r
+ We protect your rights with two steps: (1) copyright the software, and\r
+(2) offer you this license which gives you legal permission to copy,\r
+distribute and/or modify the software.\r
+\r
+ Also, for each author's protection and ours, we want to make certain\r
+that everyone understands that there is no warranty for this free\r
+software. If the software is modified by someone else and passed on, we\r
+want its recipients to know that what they have is not the original, so\r
+that any problems introduced by others will not reflect on the original\r
+authors' reputations.\r
+\r
+ Finally, any free program is threatened constantly by software\r
+patents. We wish to avoid the danger that redistributors of a free\r
+program will individually obtain patent licenses, in effect making the\r
+program proprietary. To prevent this, we have made it clear that any\r
+patent must be licensed for everyone's free use or not licensed at all.\r
+\r
+ The precise terms and conditions for copying, distribution and\r
+modification follow.\r
+\f\r
+ GNU GENERAL PUBLIC LICENSE\r
+ TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION\r
+\r
+ 0. This License applies to any program or other work which contains\r
+a notice placed by the copyright holder saying it may be distributed\r
+under the terms of this General Public License. The "Program", below,\r
+refers to any such program or work, and a "work based on the Program"\r
+means either the Program or any derivative work under copyright law:\r
+that is to say, a work containing the Program or a portion of it,\r
+either verbatim or with modifications and/or translated into another\r
+language. (Hereinafter, translation is included without limitation in\r
+the term "modification".) Each licensee is addressed as "you".\r
+\r
+Activities other than copying, distribution and modification are not\r
+covered by this License; they are outside its scope. The act of\r
+running the Program is not restricted, and the output from the Program\r
+is covered only if its contents constitute a work based on the\r
+Program (independent of having been made by running the Program).\r
+Whether that is true depends on what the Program does.\r
+\r
+ 1. You may copy and distribute verbatim copies of the Program's\r
+source code as you receive it, in any medium, provided that you\r
+conspicuously and appropriately publish on each copy an appropriate\r
+copyright notice and disclaimer of warranty; keep intact all the\r
+notices that refer to this License and to the absence of any warranty;\r
+and give any other recipients of the Program a copy of this License\r
+along with the Program.\r
+\r
+You may charge a fee for the physical act of transferring a copy, and\r
+you may at your option offer warranty protection in exchange for a fee.\r
+\r
+ 2. You may modify your copy or copies of the Program or any portion\r
+of it, thus forming a work based on the Program, and copy and\r
+distribute such modifications or work under the terms of Section 1\r
+above, provided that you also meet all of these conditions:\r
+\r
+ a) You must cause the modified files to carry prominent notices\r
+ stating that you changed the files and the date of any change.\r
+\r
+ b) You must cause any work that you distribute or publish, that in\r
+ whole or in part contains or is derived from the Program or any\r
+ part thereof, to be licensed as a whole at no charge to all third\r
+ parties under the terms of this License.\r
+\r
+ c) If the modified program normally reads commands interactively\r
+ when run, you must cause it, when started running for such\r
+ interactive use in the most ordinary way, to print or display an\r
+ announcement including an appropriate copyright notice and a\r
+ notice that there is no warranty (or else, saying that you provide\r
+ a warranty) and that users may redistribute the program under\r
+ these conditions, and telling the user how to view a copy of this\r
+ License. (Exception: if the Program itself is interactive but\r
+ does not normally print such an announcement, your work based on\r
+ the Program is not required to print an announcement.)\r
+\f\r
+These requirements apply to the modified work as a whole. If\r
+identifiable sections of that work are not derived from the Program,\r
+and can be reasonably considered independent and separate works in\r
+themselves, then this License, and its terms, do not apply to those\r
+sections when you distribute them as separate works. But when you\r
+distribute the same sections as part of a whole which is a work based\r
+on the Program, the distribution of the whole must be on the terms of\r
+this License, whose permissions for other licensees extend to the\r
+entire whole, and thus to each and every part regardless of who wrote it.\r
+\r
+Thus, it is not the intent of this section to claim rights or contest\r
+your rights to work written entirely by you; rather, the intent is to\r
+exercise the right to control the distribution of derivative or\r
+collective works based on the Program.\r
+\r
+In addition, mere aggregation of another work not based on the Program\r
+with the Program (or with a work based on the Program) on a volume of\r
+a storage or distribution medium does not bring the other work under\r
+the scope of this License.\r
+\r
+ 3. You may copy and distribute the Program (or a work based on it,\r
+under Section 2) in object code or executable form under the terms of\r
+Sections 1 and 2 above provided that you also do one of the following:\r
+\r
+ a) Accompany it with the complete corresponding machine-readable\r
+ source code, which must be distributed under the terms of Sections\r
+ 1 and 2 above on a medium customarily used for software interchange; or,\r
+\r
+ b) Accompany it with a written offer, valid for at least three\r
+ years, to give any third party, for a charge no more than your\r
+ cost of physically performing source distribution, a complete\r
+ machine-readable copy of the corresponding source code, to be\r
+ distributed under the terms of Sections 1 and 2 above on a medium\r
+ customarily used for software interchange; or,\r
+\r
+ c) Accompany it with the information you received as to the offer\r
+ to distribute corresponding source code. (This alternative is\r
+ allowed only for noncommercial distribution and only if you\r
+ received the program in object code or executable form with such\r
+ an offer, in accord with Subsection b above.)\r
+\r
+The source code for a work means the preferred form of the work for\r
+making modifications to it. For an executable work, complete source\r
+code means all the source code for all modules it contains, plus any\r
+associated interface definition files, plus the scripts used to\r
+control compilation and installation of the executable. However, as a\r
+special exception, the source code distributed need not include\r
+anything that is normally distributed (in either source or binary\r
+form) with the major components (compiler, kernel, and so on) of the\r
+operating system on which the executable runs, unless that component\r
+itself accompanies the executable.\r
+\r
+If distribution of executable or object code is made by offering\r
+access to copy from a designated place, then offering equivalent\r
+access to copy the source code from the same place counts as\r
+distribution of the source code, even though third parties are not\r
+compelled to copy the source along with the object code.\r
+\f\r
+ 4. You may not copy, modify, sublicense, or distribute the Program\r
+except as expressly provided under this License. Any attempt\r
+otherwise to copy, modify, sublicense or distribute the Program is\r
+void, and will automatically terminate your rights under this License.\r
+However, parties who have received copies, or rights, from you under\r
+this License will not have their licenses terminated so long as such\r
+parties remain in full compliance.\r
+\r
+ 5. You are not required to accept this License, since you have not\r
+signed it. However, nothing else grants you permission to modify or\r
+distribute the Program or its derivative works. These actions are\r
+prohibited by law if you do not accept this License. Therefore, by\r
+modifying or distributing the Program (or any work based on the\r
+Program), you indicate your acceptance of this License to do so, and\r
+all its terms and conditions for copying, distributing or modifying\r
+the Program or works based on it.\r
+\r
+ 6. Each time you redistribute the Program (or any work based on the\r
+Program), the recipient automatically receives a license from the\r
+original licensor to copy, distribute or modify the Program subject to\r
+these terms and conditions. You may not impose any further\r
+restrictions on the recipients' exercise of the rights granted herein.\r
+You are not responsible for enforcing compliance by third parties to\r
+this License.\r
+\r
+ 7. If, as a consequence of a court judgment or allegation of patent\r
+infringement or for any other reason (not limited to patent issues),\r
+conditions are imposed on you (whether by court order, agreement or\r
+otherwise) that contradict the conditions of this License, they do not\r
+excuse you from the conditions of this License. If you cannot\r
+distribute so as to satisfy simultaneously your obligations under this\r
+License and any other pertinent obligations, then as a consequence you\r
+may not distribute the Program at all. For example, if a patent\r
+license would not permit royalty-free redistribution of the Program by\r
+all those who receive copies directly or indirectly through you, then\r
+the only way you could satisfy both it and this License would be to\r
+refrain entirely from distribution of the Program.\r
+\r
+If any portion of this section is held invalid or unenforceable under\r
+any particular circumstance, the balance of the section is intended to\r
+apply and the section as a whole is intended to apply in other\r
+circumstances.\r
+\r
+It is not the purpose of this section to induce you to infringe any\r
+patents or other property right claims or to contest validity of any\r
+such claims; this section has the sole purpose of protecting the\r
+integrity of the free software distribution system, which is\r
+implemented by public license practices. Many people have made\r
+generous contributions to the wide range of software distributed\r
+through that system in reliance on consistent application of that\r
+system; it is up to the author/donor to decide if he or she is willing\r
+to distribute software through any other system and a licensee cannot\r
+impose that choice.\r
+\r
+This section is intended to make thoroughly clear what is believed to\r
+be a consequence of the rest of this License.\r
+\f\r
+ 8. If the distribution and/or use of the Program is restricted in\r
+certain countries either by patents or by copyrighted interfaces, the\r
+original copyright holder who places the Program under this License\r
+may add an explicit geographical distribution limitation excluding\r
+those countries, so that distribution is permitted only in or among\r
+countries not thus excluded. In such case, this License incorporates\r
+the limitation as if written in the body of this License.\r
+\r
+ 9. The Free Software Foundation may publish revised and/or new versions\r
+of the General Public License from time to time. Such new versions will\r
+be similar in spirit to the present version, but may differ in detail to\r
+address new problems or concerns.\r
+\r
+Each version is given a distinguishing version number. If the Program\r
+specifies a version number of this License which applies to it and "any\r
+later version", you have the option of following the terms and conditions\r
+either of that version or of any later version published by the Free\r
+Software Foundation. If the Program does not specify a version number of\r
+this License, you may choose any version ever published by the Free Software\r
+Foundation.\r
+\r
+ 10. If you wish to incorporate parts of the Program into other free\r
+programs whose distribution conditions are different, write to the author\r
+to ask for permission. For software which is copyrighted by the Free\r
+Software Foundation, write to the Free Software Foundation; we sometimes\r
+make exceptions for this. Our decision will be guided by the two goals\r
+of preserving the free status of all derivatives of our free software and\r
+of promoting the sharing and reuse of software generally.\r
+\r
+ NO WARRANTY\r
+\r
+ 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY\r
+FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN\r
+OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES\r
+PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED\r
+OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF\r
+MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS\r
+TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE\r
+PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,\r
+REPAIR OR CORRECTION.\r
+\r
+ 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING\r

+\f\r
+ How to Apply These Terms to Your New Programs\r
+\r
+ If you develop a new program, and you want it to be of the greatest\r
+possible use to the public, the best way to achieve this is to make it\r
+free software which everyone can redistribute and change under these terms.\r
+\r
+ To do so, attach the following notices to the program. It is safest\r
+to attach them to the start of each source file to most effectively\r
+convey the exclusion of warranty; and each file should have at least\r
+the "copyright" line and a pointer to where the full notice is found.\r
+\r
+ <one line to give the program's name and a brief idea of what it does.>\r
+ Copyright (C) <year> <name of author>\r

+ it under the terms of the GNU General Public License as published by\r
+ the Free Software Foundation; either version 2 of the License, or\r

+\r
+ This program is distributed in the hope that it will be useful,\r
+ but WITHOUT ANY WARRANTY; without even the implied warranty of\r

+\r
+\r
+Also add information on how to contact you by electronic and paper mail.\r
+\r
+If the program is interactive, make it output a short notice like this\r
+when it starts in an interactive mode:\r
+\r
+ Gnomovision version 69, Copyright (C) year name of author\r
+ Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.\r
+ This is free software, and you are welcome to redistribute it\r
+ under certain conditions; type `show c' for details.\r
+\r
+The hypothetical commands `show w' and `show c' should show the appropriate\r
+parts of the General Public License. Of course, the commands you use may\r
+be called something other than `show w' and `show c'; they could even be\r
+mouse-clicks or menu items--whatever suits your program.\r
+\r
+You should also get your employer (if you work as a programmer) or your\r
+school, if any, to sign a "copyright disclaimer" for the program, if\r
+necessary. Here is a sample; alter the names:\r
+\r
+ Yoyodyne, Inc., hereby disclaims all copyright interest in the program\r
+ `Gnomovision' (which makes passes at compilers) written by James Hacker.\r

+This General Public License does not permit incorporating your program into\r

+consider it more useful to permit linking proprietary applications with the\r
+library. If this is what you want to do, use the GNU Library General\r
+Public License instead of this License.\r

+==================\r
+\r
+ A PHP class to retrieve, parse, and organize weather data for easy\r
+ access.\r

+ Foundation, Inc., 59 Temple Place, Suite 330, Boston, MA 02111-1307\r
+ USA\r
+ \r
+ \r
+ Requirements:\r
+ PHP 4.1.0 or later, installed with cURL support\r
+ \r
+ \r
+ Summary:\r
+ pxWeather gives you easy access to National Weather Service forecasts\r
+ and current conditions for integration into your PHP application. To\r
+ improve performance and decrease load on the data source, pxWeather\r
+ can cache weather data locally.\r
+\r
+ \r
+ Download:\r
+ The latest version will always be available at\r
+ https://sourceforge.net/projects/pxweather/\r
+\r
+ \r
+ Credits:\r
+ Many thanks go to Hans Anderson for his XMLize utility, which makes\r
+ short work of XML parsing. XMLize, which is included in this \r
+ distribution, can be found at http://www.hansanderson.com/php/xml/\r
+\r
+ \r
+ Installation:\r
+ - Decompress your .zip or .tar.gz file.\r
+ - Copy pxweather.inc.php to your PHP-enabled website.\r
+ - If you use PHP5, copy xmlize-php5.inc.php to the same directory\r
+ on your website. If you use PHP4, copy xmlize-php4.inc.php.\r
+ - If you intend to use caching, create a new directory for cache\r
+ files to live. Make sure it has proper read/write permissions set.\r
+\r
+ (NOTE: by default, pxWeather will use the local subdirectory \r
+ "cache" to read/write cache files. You may use pxWeather's\r
+ setOption method to set a different directory.)\r
+\r
+\r
+ Testing Your Installation:\r
+ Test your installation with the following bit of code. This code\r
+ assumes it's running in the same directory as pxweather/xmlize and\r
+ that caching uses the default settings.\r
+ \r
+ <?php\r
+ \r
+ require_once("pxweather.class.php");\r
+ $w = new Weather();\r
+ $w->load();\r
+ echo $w->getCurrent("temp.string");\r
+ \r
+ ?>\r
+ \r
+ When you run it, you should see the current temperature for\r
+ Boston, MA in degrees Farenheit and Celsius.\r
+\r
+ \r
+ Configuring pxWeather:\r
+ All pxWeather configuration is done through the class constructor\r
+ and the class's setOption method. The examples below assume you've\r
+ already loaded pxweather.class.php, as above.\r
+ \r
+ To set a city other than Boston, MA, call the constructor with the\r
+ $city variable set:\r
+ \r
+ <?php\r
+ \r
+ $w = new Weather($city = "Miami");\r
+ \r
+ ?>\r
+ \r
+ Sometimes, two cities (i.e. Portland, ME and Portland, OR) have the\r
+ same name. So, in any case where there might be ambiguity, consider\r
+ using the ICAO location code for your city. The FAA maintains a \r
+ list of codes for the USA at\r
+ https://pilotweb.nas.faa.gov/qryhtml/icao/USA.html\r
+ \r
+ <?php\r
+ \r
+ // Portland, OR\r
+ $w = new Weather($city = "KPDX");\r
+ \r
+ // Portland, ME\r
+ $w = new Weather($city = "KPWM");\r
+ \r
+ ?>\r
+ \r
+ To force pxWeather to ignore its cache, and retrieve data directly\r
+ from the source, you can call the constructor with the $force \r
+ variable set to true:\r
+ \r
+ <?php\r
+ \r
+ $w = new Weather($city = "Austin", $force = true);\r
+ \r
+ ?>\r
+ \r
+ Other, less-common settings can be changed with the setOption method.\r
+ For example, to disable caching:\r
+ \r
+ <?php\r
+ \r
+ $w = new Weather();\r
+ $w->setOption("PXWEATHER_CACHE", false);\r
+ \r
+ ?>\r
+ \r
+ Four options may be set this way:\r
+ \r
+ PXWEATHER_URL (URL)\r
+ The URL used to retrieve XML weather data.\r
+\r
+ PXWEATHER_CACHE (true/false)\r
+ Enable/disable caching; enabled by default.\r
+\r
+ PXWEATHER_CACHEFOR (number)\r
+ Number of minutes to keep cached data; 60 by default.\r
+\r
+ PXWEATHER_CACHEAT (path)\r
+ The directory where cache files should be stored; 'cache' by\r
+ default.\r
+\r
+ \r
+ Accessing Data:\r
+ pxWeather extracts four kinds of data from the XML feed:\r
+ \r
+ 1. Current conditions\r
+ 2. Almanac times\r
+ 3. Forecasts\r
+ 4. Daycasts\r
+ \r
+ Current conditions can be retrieved with the getCurrent()\r
+ method, which takes a field name as argument. The following are\r
+ valid field names:\r
+ \r
+ FIELD NAME EXAMPLE VALUE\r
+ ----------------- ---------------------\r
+ city Boston, MA\r
+ longname Boston, MA\r
+ ident KBOS\r
+ latitude 42.37\r
+ longitude -71.03\r
+ timezone -5\r
+ daylight_saving 1\r
+ night 0\r
+ weather_code PC\r
+ observation_name KBOS (Boston, MA)\r
+ time 5 PM EDT 24 JUN 05\r
+ temp.string 86 F (30 C)\r
+ temp.F 86\r
+ temp.C 30\r
+ dewpt.string 53 F (11 C)\r
+ dewpt.F 53\r
+ dewpt.C 11\r
+ rel_hum.string 32 %\r
+ rel_hum.percent 32\r
+ wind.string SW at 17 knt\r
+ wind_direct SW\r
+ wind_speed.knt 17\r
+ heat_index.F 84\r
+ pressure.string 1016.7 mb (30.03 in)\r
+ pressure.mb 1016.7\r
+ pressure.in 30.03\r
+ skies mostly cloudy\r
+ text_weather haze\r
+ \r
+ The example from above:\r
+ \r
+ <?php\r
+ \r
+ require_once("pxweather.class.php");\r
+ $w = new Weather();\r
+ $w->load();\r
+ echo $w->getCurrent('temp.string');\r
+ \r
+ ?>\r
+ \r
+ Almanac times (sunrise, sunset) can be retrieved with the methods\r
+ getSunrise() and getSunset(). They take no arguments, and return\r
+ time strings in 12-hour format (i.e. 5:08 AM).\r
+ \r
+ Forecasts include a day name, a weather code, a low or high\r
+ temperature, and a text description of the forecast. Forecasts for\r
+ approximately the next six days and nights can be retrieved with the\r
+ getForecasts() method, which takes no arguments. The method returns\r
+ an array containing all forecasts. The example below cycles through\r
+ each forecast, translates its weather code into a readable string\r
+ with the weatherString() method, and prints high/low temperatures\r
+ and text forecast.\r
+ \r
+ <?php\r
+ \r
+ require_once("pxweather.class.php");\r
+ $w = new Weather();\r
+ $w->load();\r
+ \r
+ echo "<pre>";\r
+ \r
+ foreach($w->getForecasts() as $forecast)\r
+ {\r
+ echo "FORECAST FOR " . $forecast['day']. ":\n";\r
+ echo $w->weatherString($forecast['weather']) . "\n";\r
+ \r
+ if (isset($forecast['low_temp']))\r
+ echo "Low temperature: " . $forecast['low_temp'] . "\n";\r
+\r
+ if (isset($forecast['high_temp']))\r
+ echo "High temperature: " . $forecast['high_temp'] . "\n";\r
+ \r
+ echo "Description: " . $forecast['text'] . "\n\n";\r
+ \r
+ }\r
+ \r
+ echo "</pre>";\r
+ \r
+ ?>\r
+ \r
+ Daycasts are very similar to forecasts, but are not split into \r
+ individual day and night reports and do not have text forecast\r
+ descriptions. An example like above:\r
+ \r
+ <?php\r
+\r
+ require_once("pxweather.class.php");\r
+ $w = new Weather();\r
+ $w->load();\r
+ \r
+ echo "<pre>";\r
+ \r
+ foreach($w->getDaycasts() as $daycast)\r
+ {\r
+ echo "DAYCAST FOR " . $daycast['day']. ":\n";\r
+ echo $w->weatherString($daycast['weather']) . "\n";\r
+\r
+ if (isset($daycast['low_temp']))\r
+ echo "Low temperature: " . $daycast['low_temp'] . "\n";\r
+\r
+ if (isset($daycast['high_temp']))\r
+ echo "High temperature: " . $daycast['high_temp'] . "\n\n";\r
+ }\r
+ \r
+ echo "</pre>";\r
+ \r
+\r
+ ?>\r
+ \r
+ If you want to inspect the entire weather data structure, use the \r
+ toString() method:\r
+ \r
+ <?php\r
+ \r
+ require_once("pxweather.class.php");\r
+ $w = new Weather();\r
+ $w->load();\r
+ \r
+ $w->toString();\r
+ \r
+ ?>\r
+\r
+ \r

+ SourceForge hosts a variety of forums to express your constructive\r
+ feedback:\r
