+
+ 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 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. |

RGraph: HTML5 canvas graph library - Adjusting your graphs interactively
+
+
+
+
+
+
+
+
+
+
+
+
+ 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.
+
+
+
+
+ At the current time this feature on the Bar and Line charts don't work with X axis in the center.
+
+
+
+
+ If your intention is to make some sort of interactive console, new HTML5 input types may also be of interest (for example the new range input type
+ which gives you a "slider bar"). Eg (Chrome/Safari/Opera):

+ RGraph: HTML5 canvas graph library - Animating your graphs
+
+
+
+

RGraph: HTML5 canvas graph library - Animating your graphs
+
+
+
+
+
+
+
+
+ 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 RGraph.Clear(canvas), passing it your canvas object that is returned by
+ document.getElementById(). 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.
+
+
+
+ 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 chart.ymax property.
+
+
+
+ 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.
+
+
+
Animation using jQuery
+
+
+
+
+
+
+
+
+
+
+ You can if you prefer use an external library for animation, like jQuery.
+
+
+
+ The graph to the right is animated using
+ jQuery. In the example the width is maintained by placing the canvas within a DIV which has the width/height CSS
+ attributes set.
+
RGraph: HTML5 canvas graph library - Annotating your graphs
+
+
+
+
+
+
+
+
+ The annotations feature brings presentation style functionality to RGraph graphs. You can use this feature
+ for highlighting your graphs if you need to.
+
+ Enabling annotations is a very simple affair, and consists of doing the following:
+
+
+
myGraph.Set('chart.annotatable', true);
+
+
+
Browser support
+
+
+ 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.
+
+
+
+
What can I use annotations for?
+
+
+ As mentioned you can use it for presentations, highlighting things to yourself or others or just to have fun drawing (!).
+
+
+
+
Are annotations persistent?
+
+
+ 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.
+
+
+
+
How do I show the mini-palette?
+
+
+
+ You can show the palette by using the RGraph.Showpalette function shown below as a context menu item:
+
+ This code will result in the same context menu as the graph above.
+
+
+
+
How can I clear the annotations?
+
+ You can simply clear the graph and redraw it:
+
+
RGraph.Clear(myGraph.canvas); // Clear the graph
+myGraph.Draw(); // Redraw it
+
+
+ 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.
+
+
+
+
Replaying annotations when they're off
+
+
+ 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 RGraph.ReplayAnnotations(object) after the call to .Draw().

+ RGraph: HTML5 canvas graph library - API documentation
+
+
+
+
+
+
+
+
+
+
+
+
+
+
+
+
+ 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:
+
+ RGraph.common.core.js 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 RGraph.common.zoom.js,
+ so if you don't need zoom, you don't need this file.
+ Each of the graph libraries (RGraph.*.js) contains that particular graphs class. If you'd like to see a "bare bones"
+ implementation, you can look at the basic example. There's also a
+ skeleton example to make it easier to create new graph types.
+
+
+
+
Canvas and context references
+
+
+ Each graph object maintains references to the context and canvas as properties. So to get hold of them all you
+ need to do is this:
+
+
+
+<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>
+
+
+
+
Working with events
+
+
+ When working with events, you may come across the situation where you have a reference to the canvas, 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:
+
+
+
+<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>
+
+
+
+
Working with graph coordinates
+
+
+ For most graph types, the coordinates of elements (eg bars, lines etc) are to be found in the class variable obj.coords.
+ 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.
+
+
+
+ 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.
+
+
+
+var myCoords = myBar.coords;
+
+
+
+ Note: 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.
+
+
+
+
Working with graph data
+
+
+ Another variable you may need is the data 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 original_data. 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.
+
+
+
+ Not all graph types use the data 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 below1.
+
For the Scatter chart, each data point is an array of X/Y coordinates, the color and the tooltip for that point.
+
+ The Line chart obj.original_data is an aggregation of all the datasets given to the Line chart, so the first
+ dataset is held in obj.original_data[0], the second in obj.original_data[1] etc.
+
+
+
+
+
Updating your graphs dynamically
+
+
+ Note:
+ 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 Number() or parseInt() functions. For example:
+
+
+
+<script>
+ num = Number('23');
+ num = parseInt('43');
+</script>
+
+
+
+ A common request is to be able to update graphs dynamically. This is quite simple and consists of three steps:
+
+
+
+
Get the new data from the server (with an AJAX request for example).
+
Set the data in your graph object. See the above table for the appropriate property to use.
+
Call the .Draw() method again.
+
+
+
+ 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 here.
+
+
+
+
+
Setting properties
+
+
+ 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.
+
+ 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 __xxx__, and you can inspect the
+ objects by using a console(eg the inspector that's part of Google Chrome - CTRL+SHIFT+J). Some examples are:
+
+
+
+
__object__ on the canvas - a reference to the graph object
+
+ RGraph.Registry.Get('chart.tooltip') - a reference to the currently visible tooltip. This in turn has the following
+ available:
+
+
__text__ - Since setting .innerHTML can cause changes in HTML, this is the original tooltip text.
+
__index__ - This is the numerical index corresponding to the tooltips array that you set.
+
__dataset__ - Used in the Scatter chart and corresponding to the dataset.
+
__canvas__ - A reference to the original canvas that triggered the tooltip.
+
+
+
+ RGraph.Registry.Get('chart.mousedown') - Used in annotating, and stipulates whether the mouse button is currently
+ pressed.
+
+
+ RGraph.Registry.Get('chart.contextmenu') - The currently shown context menu, if any. This in turn has the following
+ properties:
+
+
__canvas__ - The original canvas object.
+
+
+
+
+ These are just a sample of what's available, to find more you should use an introspection tool, look at the source, or ask
+ on the support mailing list.
+
+
+
+
+
Scale information
+
+ For the Bar, Bipolar, HBar, Line and Scatter charts the scale that is used is stored in the scale class variable. Eg:
+
+
+
+<script>
+ var myBar = new RGraph.Bar('cvs', [56,43,52,54,51,38,46,42,52]);
+ myBar.Draw();
+
+ var myScale = myBar.scale
+</script>
+
+
+
+
Adding text to your graphs
+
+ If you want to add arbitrary text to your graph(s) you can use the API function RGraph.Text().
+
+
+
+<script>
+ // Draw a basic graph
+ var myObj = new RGraph.Bar('myCanvas', [4,5,5,8,7,6,4,8,5,9]);
+ myObj.Draw();
+
+ // Draw some text
+ myObj.context.beginPath();
+ size = 12;
+ font = 'Verdana';
+ text = 'Some text!;
+ x = 10;
+ y = 10;
+
+ RGraph.Text(myObj.context, font, size, x, y, text);
+ myObj.context.fill();
+</script>
+
+
+
+

Miscellaneous
+
+
+

+ It tries to add:
+
+
+
pageX (MSIE)
+
pageY (MSIE)
+
target (MSIE)
+
stopPropagation() (MSIE)
+
offsetX (FF)
+
offsetY (FF)
+
+ File: RGraph.common.core.js
+
+
+
(null) RGraph.OldBrowserCompat(context) This function "fills in" any required functions that some browsers don't have. At the moment this consists of adding the measureText() and fillText() functions to the context when they're missing (usually this means older versions of Opera). File: RGraph.common.core.js
+
(number) RGraph.GetDays(date) This returns the number of days in the given month. The argument should be a Date object. File: RGraph.common.core.js
+

+
+ (null) RGraph.ClearAnnotations(id) 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:
+
+
+function ClearAndRedraw (obj)
+{
+ RGraph.Clear(obj.canvas); // This function also calls the RGraph.ClearAnnotations() function
+ obj.Draw();
+}
+ File: RGraph.common.annotatate.js
+
+
(null) RGraph.ReplayAnnotations(object) 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. File: RGraph.common.annotate.js
+
(array) RGraph.getMouseXY(event) When passed your event object, it returns the X and Y coordinates (in relation to the canvas) of the mouse pointer. (0,0) is in the top left corner, with the X value increasing going right and the Y value increasing going down. File: RGraph.common.core.js
+
(array) RGraph.getCanvasXY(event) Similar to the above function but returns the X/Y coordinates of the canvas in relation to the page. File: RGraph.common.core.js
+
(number) RGraph.degrees2Radians(number) Converts and returns the given number of degrees to radians. 1 radian = 57.3 degrees. File: RGraph.common.core.js
+
(array) RGraph.getScale(max, obj) Given the maximum value this will return an appropriate scale. The second argument is the graph object. File: RGraph.common.core.js
+
(mixed) RGraph.Registry.Get(name) In conjunction with the next function, this is an implementation of the Registry pattern which can be used for storing settings. File: RGraph.common.core.js
+
(mixed) RGraph.Registry.Set(name, value) In conjunction with the previous function, this is an implementation of the Registry pattern which can be used for storing settings. File: RGraph.common.core.js
+
(null) RGraph.Register(object) 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. File: RGraph.common.core.js
+
+
+ (null) RGraph.Redraw([id, [color]]) 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.
Note: 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. File: RGraph.common.core.js
+
+
+
(null) RGraph.SetShadow(object, color, offetX, offsetY, blur) 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. File: RGraph.common.core.js
+
(null) RGraph.NoShadow(object) This function is a shortcut function used to "turn off" the shadow. The argument is your graph object. File: RGraph.common.core.js
+
(array) RGraph.getSegment(event) 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:
The center X coordinate
The center Y coordinate
The radius
The start angle (in degrees)
The end angle (in degrees)
Angles are measured starting from the "east" axis. File: RGraph.common.core.js
+
+ (number) RGraph.Async(mixed[, delay]) 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 here. 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.
+
+
+ Note: 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.
+
+ File: RGraph.common.core.js
+
+
+
+ (null) RGraph.filledCurvyRect(context, x, y, width, height[, radius[, curvy top left[, curvy top right[, curvy bottom right[, curvy bottom left]]]]])
+ This draws a rectangle with curvy corners. Similar to the built in rectangle functions, and you can control
+ individual corners. The radius controls the severity of the corner curvature and defaults to 3. By default all
+ the corners are curvy. File: RGraph.common.core.js
+
+
+
+ (null) RGraph.strokedCurvyRect(context, x, y, width, height[, radius[, curvy top left[, curvy top right[, curvy bottom right[, curvy bottom left]]]]])
+ This draws a rectangle with curvy corners. Similar to the built in rectangle functions, and you can control
+ individual corners. The radius controls the severity of the corner curvature and defaults to 3. By default all
+ the corners are curvy. File: RGraph.common.core.js
+
+
+
+
+
Custom RGraph event related functions
+
+
+
(null) RGraph.AddCustomEventHandler(object, event, callback) This attaches a function to the spacified event. The object argument is your graph object, the event argument should be the name of the event, eg ontooltip, and the function argument is your function which handles the event. File: RGraph.common.core.js
+
(null) RGraph.FireCustomEvent(object, event) This fires a custom event. The object is your graph object, and the name is a string specifying the name of the event. File: RGraph.common.core.js
+
+
+
+
Other
+
+
+ These are functions which are less generic, and used to build the graphs. You may still wish to use them however.
+
+
+
+
(null) RGraph.lineByAngle(context, x, y, angle, length) This function draws a line from the given X and Y coordinates at the specified angle. File: RGraph.common.core.js
+
+
+ (null) RGraph.Text(context, font, size, x, y, text[, valign[, halign[, border[, angle[, background[, bold[, indicator]]]]]]])
+ This function acts as a wrapper around the canvas text functionality. The arguments are:
+
+
+
The context is the canvases 2D context.
+
The font is the name of the font you want to use (eg Arial).
+
The size is an integer specifying the size of the text, (measured in points).
+
The x and y arguments are the X/Y coordinates at which to draw the text.
+
The text argument is the text to draw.
+
The optional valign argument is the vertical alignment and can be either top, center or bottom.
+
The optional halign argument is the horizontal alignment and can be left, center or right.
+
The optional border argument is a boolean (true or false) controlling whether the text has a border.
+
The optional angle argument specifies the angle at which the text is drawn (rotated around the X/Y coordinates and measured in degrees).
+
The optional background argument is the color of the background, (eg #fff).
+
The optional bold argument is boolean which controls whether the text is bold or not.
+
And the optional indicator argument is a boolean which controls whether a placement indicator is shown.
+
+
+ File: RGraph.common.core.js
+
+
+
+
(null) RGraph.DrawTitle(canvas, text, gutter[, centerx[, size]]) This function draws the title. The centerx argument is the center point to use. If not given the center of the canvas is used. File: RGraph.common.core.js
+
(null) RGraph.Tooltip(canvas, text, x, y, idx) This function shows a tooltip. The idx value corresponds to the tooltip array that you give. File: RGraph.common.tooltips.js
+
(null) RGraph.DrawKey(object, key, colors) This function draws the key. The first argument is the graph object, the second is an array of key information and the last is an array of the colors to use. File: RGraph.common.core.js

+
(null) RGraph.DrawInGraphLabels(object) This draws the in-graph labels. The argument is the graph object. File: RGraph.common.core.js
+
(null) RGraph.DrawCrosshairs(object) This function draws the crosshairs. The argument is the graph object. File: RGraph.common.core.js
+
(null) RGraph.HideContext() This function clears the context menu. RGraph uses it to hide the context menu, but only AFTER your function/callback is run. You may wish to hide the context menu before your own function, in which case you can call this function. File: RGraph.common.context.js
+
+ (null) RGraph.showPNG([canvas[, event]])
+ This function allows you to easily facilitate getting a PNG image representation of your graph.
+ You can use it like this:
+
+
+ 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 here). It WAS originally designed to be used with a context menu, hence it's part of the RGraph.core.context.js
+ file.
+ File: RGraph.common.context.js
+
+
+
+
+ (number) RGraph.getGutterSuggest(obj, data)
+ This function returns a suggested gutter setting based on the vertical labels. If the bottom labels are larger, this
+ setting may be inappropriate. The data variable is a simple single dimension array, eg [1,2,3,4,5].

The skeleton file
+
+ The skeleton object
+ (RGraph.skeleton.js) gives you a base for creating new graph types that
+ match the RGraph object system (eg getters, setters, RGraph names etc). Example usage of the skeleton object would be:
+
+
+
+<script>
+ var myObj = new RGraph.Skeleton('cvs', [3,3,4,5,3,8,3,2,1,9]);
+ myObj.Set('chart.colors', ['red']);
+ myObj.Draw();
+
+ var colors = myObj.Get('chart.colors');
+</script>

Questions
+
+
+ If you have a question regarding the API, you can ask it on the
+ mailing list
+
+
+
+
+
+ These images are here to pad the page and slow down loading so that the window.onload event is slowed. This makes the
+ difference far more visible.
+
+
+
+
+
+
+
+ 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 RGraph.Async() 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.
+
+
+
+ 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.
+
All your libraries must be loaded first. In the pages <head> for example. If not, you won't be able to create your graphs.
+
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.
+
+ 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.
+
+
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.
+
+ 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.

RGraph: HTML5 canvas graph library - About canvas color definitions
+
+
+
+
+ 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.
+
+ The first, and easiest, is to use named colors. This gives you a range of color values that have been predefined for you. Eg:
+
+
+
myObject.Set('chart.colors', ['red', 'blue']);
+
+
+
+
Hex values
+
+
+ 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:
+
+ 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:
+
+ 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:
+
+ 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:
+
+
+
myObject.Set('chart.colors', [myGradient]);
+
+
+
+
Radial gradients
+
+
+ Radial gradients are much like their linear counterparts, but circular, as the name suggests. Eg:
+
+ 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:
+
+
+
myObject.Set('chart.colors', [myGradient]);
+
+
+
+

+
+
+ You can read more about CSS3 color definitions here.

+ RGraph: HTML5 canvas graph library - combining bar and line graphs
+
+
+
+
+
+
+
+
+
+
+
+
+
+
+
+
+
+
+
+
+
+
+
+
+
+
+
+
+
+
+ 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.
+
+
+
+ If the values for the line and bar result in different Y scales you may need to specify the chart.ymax 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.
+
+
+ Tooltips
+
+
+ You can have tooltips on the Line chart by setting chart.tooltips.highlighting to false, 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.
+
+
+
line.Set('chart.tooltips.highlighting', false);
+
+
+ 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.
+
+
+
+
Combining Line charts
+
+
+
+
+
+
+ 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.
+
+
+
+ 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.
+
+
+
+ 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. See the line chart example page
+
+ 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.
+
+
+
+ Important: 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.
+
+
+
+
+
What do they look like?
+
+
+
+
+ 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 RGraph_contextmenu_background, RGraph_contextmenu and RGraph_contextmenu_item. Eg:
+
+ 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.
+
+
+
+
+
Can I have multiple levels of menus?
+
+
+ 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:
+
+ 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.
+
+
+
+
+
Can I have "separators"?
+
+
+ Yes. Simply pass null instead of an array as your menu item. Eg:
+
+ 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.
+
+
+
+
+
What can I use them for?
+
+
+ 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:
+
+
+
+
+
+
+
+
Is there an example file that uses the CSS classes?
+ 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.
+

+
+
+
+
+
RGraph_zoom_window
+
+ This is the class to use if you want to customise the mini-zoom window.
+
+
+
+

+
+
+
+
ModalDialog_background
+
+ This class controls the dark semi-opaque background for the ModalDialog.

+
+
ModalDialog_dialog
+
+ This class controls the ModalDialog itself.
+
+
+
+
+
ModalDialog_topbar
+
+ This class controls the top bar for the ModalDialog. You could, for example, use the display CSS property to
+ hide this if you don't want it.
+
+
+
+
+
Example usage
+
+ 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:
+
+ 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:

RGraph: HTML5 canvas graph library - DOMContentLoaded example
+
+
+
+
Waiting for onload event...
+
+
+
+
+
+
+
+
+
+ These images are here to pad the page and slow down loading so that the window.onload event is slowed. This makes the
+ difference far more visible.
+
+
+
+
+
+ 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).
+
+
+
+ You can read more about the DOMContentLoaded event on the Mozilla site, here,
+ and the Microsoft site here.
+
RGraph: HTML5 canvas graph library - Updating your graphs dynamically
+
+
+
+
+
+
+
+ The example on the right shows a line chart that automatically updates itself every 250 milliseconds. An ideal
+ use for this could be showing a networks bandwidth usage, or a servers load value.
+
+
+
+ This particular example shows a stacked line chart with two data series, though if you're showing load/stress values, a
+ non-filled chart might be a better choice.
+
+
+
+ To get up-to-date data from your server you could simply have the page refresh itself, storing the data on the server,
+ or use AJAX if you want the data stored client-side.
+
+
+
+ Be careful of the data types you use to pass the data to RGraph - you should use numbers to represent values, not strings.
+
+
+
+
+
+<canvas id="cvs" width="600" height="250">[No canvas support]</canvas>
+
+<script>
+ d1 = [];
+ d2 = [];
+
+ // Pre-pad the arrays with 100 null values
+ for (var i=0; i< 100; ++i) {
+ d1.push(null);
+ d2.push(null);
+ }
+
+ function getGraph(id, d1, d2)
+ {
+ var graph = new RGraph.Line(id, d1, d2);
+ graph.Set('chart.gutter', 25);
+ graph.Set('chart.background.barcolor1', 'white');
+ graph.Set('chart.background.barcolor2', 'white');
+ graph.Set('chart.title.xaxis', 'Time');
+ graph.Set('chart.filled', true);
+ graph.Set('chart.fillstyle', ['#daf1fa', '#faa']);
+ graph.Set('chart.colors', ['rgb(169, 222, 244)', 'red']);
+ graph.Set('chart.linewidth', 3);
+ graph.Set('chart.ymax', 20);
+ graph.Set('chart.xticks', 25);
+
+ return graph;
+ }
+
+ function drawGraph (e)
+ {
+ // Clear the canvas and redraw the graph
+ RGraph.Clear(document.getElementById("cvs"));
+ var graph = getGraph('cvs', d1, d2);
+ graph.Draw();
+
+ // Add some data to the data arrays
+ d1.push(RGraph.random(5, 10));
+ d2.push(RGraph.random(5, 10));
+
+ // Get rid of the first values of the arrays
+ if (d1.length > 100) {
+ d1 = RGraph.array_shift(d1);
+ d2 = RGraph.array_shift(d2);
+ }
+
+ setTimeout(drawGraph,250);
+ }
+
+ drawGraph();
+</script>
+
+ 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 RGraph.AddCustomEventListener() 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.
+
+
+
<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();
+
+ /**
+ * 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
+ */
+ RGraph.AddCustomEventListener(line, 'ontooltip', myFunc);
+ }
+
+ /**
+ * 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
+ */
+ 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>
+
+
+
+
Available events
+
+
+
+ ontooltip
+ 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. contract, expand & snap, will not function). You
+ can find the tooltip object in the RGraph registry - RGraph.Registry.Get('chart.tooltip'). 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, console.log() (you can use the
+ cl() shortcut in RGraph).
+
+
+
+
+ oncontextmenu
+ 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: RGraph.Registry.Get('chart.contextmenu') Like the ontooltip event, using alert() can
+ pause the fade in timers, so you should consider using the Firebug/Webkit console.log functions instead.
+
+
+
+
+ onbeforedraw
+ Much like the ondraw event, however this fires at the start of the .Draw() method, in effect "before" the method.
+
+
+
+
+ ondraw
+ The ondraw event fires after 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.
+
+
+
+ Note: The ondraw 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.
+
+
+
+
+ onzoom
+ The onzoom event fires whenever the canvas is zoomed. When the zoom is in area and canvas modes this fires once,
+ but when in thumbnail mode this event is like the onmousemove event in that it fires whenever the mouse is moved.
+
+
+
+
+ onmodaldialog
+ 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:
+
+
ModalDialog.AddCustomEventListener('onmodaldialog', function () {alert('Hello world!');});
+
+
+
+
+ onresize
+ The onresize event fires when a canvas is resized. It also fires when the canvas is reset to the original size.
+
+
+
+
+ onadjust
+ 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.
+
+
+
+
+ onannotatestart
+ The onannotatestart event fires at the beginning of the annotating procedure (ie in a similar vein to the onmousedown event).
+
+
+
+
+ onannotate
+ The onannotate event fires when the graph has been annotated. It fires during the annotate procedure.
+
+
+
+
+ onannotateend
+ The onannotateend event fires at the end of the annotating procedure (ie in a similar vein to the onmouseup event).
+
+ 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.
+
+
+
+ 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.
+
+
+
+ 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 RGraph license, then the ModalDialog is part of that.
+
+
+
+
+
+<script src="RGraph.common.core.js">
+<script src="RGraph.common.context.js">
+<script src="RGraph.line.js">
+<script src="RGraph.modaldialog.js">
+
+<script>
+ window.onload = function ()
+ {
+ /**
+ * Draw the line graph
+ */
+ var line = new RGraph.Line('myLine', [45,12,16,18,44,54,23,21,56,58,33,47]);
+ line.Set('chart.background.barcolor1', 'white');
+ line.Set('chart.background.barcolor2', 'white');
+ line.Set('chart.tickmarks', null);
+ line.Set('chart.hmargin', 10);
+ line.Set('chart.linewidth', 3);
+ line.Set('chart.shadow', true);
+ line.Set('chart.shadow.offset', 2);
+ line.Set('chart.labels', ['Jan', 'Feb', 'Mar', 'Apr', 'May', 'Jun', 'Jul', 'Aug', 'Sep', 'Oct', 'Nov', 'Dec']);
+ line.Set('chart.title', 'A line graph with context menu');
+
+ // This defines a context menu which calls the given function. This function in turn shows the dialog
+ line.Set('chart.contextmenu', [['Login to admin area...', function () {ModalDialog.Show('myDialog', 300);}}]]);
+
+ line.Draw();
+ }
+</script>
+
+
+ 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
+ "css" directory.
+
+
+
+
Note about Microsoft Internet Explorer 8 and the ModalDialog
+
+
+ Microsoft Internet Explorer 8 only supports fixed positioning in strict rendering mode, therefore you must specify a DTD
+ when using this browser. Eg:
+
+
+
+<!DOCTYPE html >
+
+
+
+
Hiding the ModalDialog
+
+ To hide the ModalDialog (from a "Cancel" button for example), you can use the Close() method:
+
+ You can customise the appearance of the ModalDialog by using three CSS classes, which are documented here.
+ This page customises the dialog slightly by changing the shadow X/Y offsets:
+
+
+
+<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>
+
+
+
+
ModalDialog integration
+
+ 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 ModalDialog.Show(id, width).
+ The id is the id of the layer to use. Only the .innerHTML is used, not the layer itself, so it can be hidden by
+ setting the display CSS display property to none. The width is a number which is used as the width of the dialog.
+
+
+
+ The only library needed for the ModalDialog to work is RGraph.modaldialog.js - you do not need to use
+ RGraph.common.js. This makes for far smaller download requirements.
+
+
+ This is a funnel chart. It can be used to illustrate stages of a sales or order fulfillment process, and in doing so highlight any bottlenecks
+ or steps where large amounts of customers are lost.
+
+chart.gutter
+ The gutter of the chart. This is the whitespace area around the chart. Default: 25
+
+
Colors
+chart.colors
+ These are the colors used for each segment. Default: ['red', 'green', 'gray', 'blue', 'black', 'white']
+
+
Labels and text
+chart.labels
+ An array of the labels to be used on the graph. Default: An empty array
+
+chart.text.font
+ The font used to render the text. Default: Verdana
+
+chart.text.color
+ The color of the labels. Default: black
+
+chart.text.size
+ The size (in points) of the labels. Default: 10
+
+chart.text.boxed
+ Whether the text is contained within a white bounding box. In some cases this can help readability. Default: true

+
+
Titles
+chart.title
+ The title of the graph, if any. Default: null
+
+
+chart.title.background
+The background color (if any) for the title.
+Default: null
+
+
+chart.title.hpos
+ This allows you to completely override the horizontal positioning of the title. It should be a number between 0 and 1, and is multiplied with the whole width of the canvas and then used as the horizontal position. Default: null
+
+chart.title.vpos
+ This allows you to completely override the vertical positioning of the title. It should be a number between 0 and 1, and is multiplied with the gutter and then used as the vertical position. It can be useful if you need to have a large gutter. Default: null
+
+chart.title.color
+ The color of the title. Default: black
+
+
Shadow
+chart.shadow
+ Whether a drop shadow is applied to the Funnel chart. The funnel is the first to use the canvas shadow API, and as such they won't be supported on all browsers. Currently only Safari 4+ (possibly earlier versions too), Firefox 3.5+ and Chrome 2+ support canvas shadows. Default: false
+
+chart.shadow.color

+
+chart.annotatable
+ Whether annotations are enabled for the chart (ie you can draw on the chart interactively. Default: false
+
+chart.annotate.color
+ If you do not allow the use of the palette, then this will be the only colour allowed for annotations. Default: black
+
+chart.resizable
+ Defaulting to false, this determines whether your graph will be resizable. Because of the numerous event handlers this has to install code on, This feature is unlikely to work with other dynamic features (the context menu is fine however). Default: false

+ Default: false
+
+
+ chart.key.shadow.color

+ Default: 2
+
+
+ chart.key.shadow.offsety
+ The Y offset of the shadow.
+ Default: 2
+
+ chart.key.rounded
+ This controls whether the corners of the key (in graph mode) are curved. If the key is gutter mode, this has no effect.

Adding events to your Gantt chart
+
+
+ To add events, you specify them using the chart.events property. You could use the following to set some events on your gantt chart:
+
+ The first value is the (zero indexed) start number relative to your chart.xmax. So if you have set your chart.xmax 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 -
+ ['July', 'August'].
+
+
+
+ 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.
+
+
+
+ The third value is the "percentage complete" indicator. This is shown to the right of the event, and is optional - you can
+ specify null if you wish.
+
+
+
+ The fourth value is the label that is used on the left hand side.
+
+
+
+ The optional fifth value stipulates the background colour that the bar is. Default is white.
+
+
+
+ And the last optional 6th value is the foreground color of the bar. Defaulting to #0c0.
+
+ 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.

+ 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 it can save you
+ money...).
+
+
+
+ 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.
+
+
+
+ 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.
+
+ Since the graphs are produced using HTML5 features (the new canvas tag), client support is currently:
+
+
+
+
Mozilla Firefox 3.0+
+
Google Chrome 1+
+
Apple Safari 3+
+
Opera 9.5+
+
Microsoft Internet Explorer 8+ (see note)
+
iPhone (text support from iOS v4+)
+
iPad (text support from iOS v4.2+)
+
+
+
+ The HTML5 canvas tag is part of the HTML5 specification,
+ and all of the above browsers have some sort of support for it.
+
+
+
+ Canvas & Microsoft Internet Explorer (MSIE)
+ Microsoft Internet Explorer 8 doesn't natively support the HTML5 <canvas> tag. To support
+ MSIE 8 you will need to use either
+ Google Chrome Frame or
+ ExCanvas from Google
+ (which is included in the RGraph archive). Read more about Internet Explorer compatibility
+ here.
+
+
+
+
+ Starting with preview 3 Microsoft Internet Explorer 9 has full support for <canvas>. You can view some screenshots
+ here.
+ MSIE 6 and 7 are supported by way of Google Chrome Frame.
+
+
+
+
+ RGraph and older browsers
+ 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.
+
+
+
+
+
Improving the performance of your graphs
+
+
+ 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:
+
+
+
+
+ Compression 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! If you do only one thing to aid performance,
+ then it should be this.
+
+
+ To achieve this with Apache you have a few options:
+
+
+
+
You can use the Apache module mod_gzip which compresses the libraries on the fly.
+
+ 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 AddEncoding gzip .js). If you have some sort of
+ release process/script, it would make sense to add this to it to automate the procedure.
+
+
+
+
+
+
+ Minification
+ 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.
+
+
+ You can get pre-minified versions of the libraries here.
+
+
+
+
+
+
+ Pre-emptive caching
+ 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 defer="defer" 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.
+
+
+
+
+
+ Caching
+ 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.
+
+
+
+
+
+ Script tag placement
+ According to Yahoo! guidelines 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.
+
+
+
+ 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.
+
+
+
+ Between the onload event, asychronous Javascript and careful tag placement, you will need to experiment to get the right result
+ for you.
+
+
+
+ Document structure
+ 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.
+
+
+
+
+ Creating your graphs asynchronously
+ 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 here.
+
+
+
+ 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.
+
+
+
+ DOMContentLoaded event
+ Using this event can speed up the display of your graphs signifcantly compared to the more well known onload 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.
+
+
+ You can read more about the DOMContentLoaded event on the Mozilla site, here,
+ and the Microsoft site here.
+ There's an example here.
+
+
+
+
+ AJAX requests
+ 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 below.
+
+
+
+
+ Combining libraries
+ 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.
+
+
+ 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.
+
+
+
+
+ A reasonable performance strategy
+
+
+ Although there's a lot you can do in regards to performance, a few of the points here will suffice for most
+ websites:
+
+
+
Compression
+
Minification
+
Pre-emptive caching
+
Caching
+
+
+ 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 here,
+ 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.
+
+
+
+
+
+
+
+
+
Implementing RGraph
+
+
+ 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
+ Firefox along with Firebug - 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 Web Developer toolbar
+ 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.
+
+
+
+
+ Include the libraries (put this in your documents <HEAD>):
+
+<script src="RGraph.common.core.js"></script>
+
+<script src="RGraph.common.adjusting.js"></script> <!-- Just needed for adjusting -->

+<script src="RGraph.tradar.js"></script> <!-- Just needed for traditional radar charts -->
+<script src="RGraph.vprogress.js"></script> <!-- Just needed for vertical progress bars -->
+
+
+
+
+ Add the canvas tag (put it where you want the graph to appear):
+
+ Create the graph (since it is using the onload event, you can put this anywhere):
+
+
+<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>
+
+
+
+
+
+ There's also a very basic example of using RGraph, that does very little. It can be helpful to
+ illustrate how you can get RGraph up and running.
+
+
+
Common library split (17th April 2010)
+
+ 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 RGraph.common.js is now
+ called RGraph.common.core.js.
+
+
+
+
+
Suggested structure for RGraph
+
+
+
+
+ The suggested layout structure for the RGraph libraries is shown on the right. The www.example.com folder represents
+ the root/top level of your website with the javascript directory beneath that. The css and images
+ folders are shown for
+ illustrative purposes only. If you follow this layout then your URLs to the RGraph libraries would be:
+
+ 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.
+
+
+
+
+
+
+
Integration with server side scripting
+
+
+ This is a very easy process, as easy as sending content to the browser. All you need to do is make the data variable
+ (as in the example below) contain the data you want to be displayed. Eg:
+
<?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>');
+?>
+
+
+
+ Strictly speaking the var isn't necessary, however if you put the code inside a
+ function (like window.onload), it's probably best to do so as using var will
+ make the variable local, and not global. So doing so will help prevent naming clashes.
+
+
+
+
+
+
Integration with PHP & MySQL
+
+
+ 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):
+
+
+
+#
+# Table structure for table `daily_statistics`
+#
+
+CREATE TABLE `daily_statistics` (
+ `st_day` char(9) NOT NULL,
+ `st_statistics` tinyint(4) NOT NULL,
+ 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 ('Tue', 95);
+INSERT INTO `daily_statistics` VALUES ('Wed', 64);
+INSERT INTO `daily_statistics` VALUES ('Thu', 94);
+INSERT INTO `daily_statistics` VALUES ('Fri', 75);
+INSERT INTO `daily_statistics` VALUES ('Sat', 98);
+INSERT INTO `daily_statistics` VALUES ('Sun', 84);
+
+
+
+<?php
+ /**
+ * Change these to your own credentials
+ */
+ $hostname = "localhost";
+ $username = "root";
+ $password = "PASSWORD";
+ $database = "RGraph_example";
+
+ $connection = mysql_connect($hostname, $username, $password) OR die('Could not connect to MySQL: ' . mysql_error());
+ mysql_select_db($database);
+
+ $result = mysql_query("SELECT st_day, st_statistics FROM daily_statistics");
+ if ($result) {
+
+ $labels = array();
+ $data = array();
+
+ while ($row = mysql_fetch_assoc($result)) {
+ $labels[] = $row["st_day"];
+ $data[] = $row["st_statistics"];
+ }
+
+ // Now you can aggregate all the data into one string
+ $data_string = "[" . join(", ", $data) . "]";
+ $labels_string = "['" . join("', '", $labels) . "']";
+ } else {
+ print('MySQL query failed with error: ' . mysql_error());
+ }
+?>
+<html>
+<head>
+
+ <!-- Don't forget to update these paths -->
+
+ <script src="libraries/RGraph.common.core.js" ></script>
+ <script src="libraries/RGraph.line.js" ></script>
+
+</head>
+<body>
+
+ <canvas id="cvs" width="600" height="250">[No canvas support]</canvas>
+ <script>
+ graph = new RGraph.Line('cvs', <?php print($data_string) ?>);
+ graph.Set('chart.background.grid.autofit', true);
+ graph.Set('chart.gutter', 17);
+ graph.Set('chart.hmargin', 10);
+ graph.Set('chart.tickmarks', 'endcircle');
+ graph.Set('chart.labels', <?php print($labels_string) ?>);
+
+ graph.context.translate(12, 0);
+
+ graph.Draw();
+ </script>
+
+</body>
+</html>
+
+
+
+ This PHP code provides the data in two strings - $labels_string and $data_string. These variables are then used
+ in the RGraph code to provide the data and the labels.
+
+
+
Remember:
+
+
+
Change the database hostname/username/password/database to match your own.
+
Ensure you have the correct paths to the RGraph libraries.
+
+
+
+
+
Making AJAX requests
+
+
+ Note:
+ 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 Number() or parseInt() functions. For example:
+
+
+
+<script>
+ num = Number('23');
+ num = parseInt('43');
+</script>
+
+
+
+ Here is a simple function that you could use to get data from your server using AJAX:
+
+
+
+<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>
+
+ Support is available via a Google Groups forum. If you think that the issue you have is common, try the issues
+ page first, and then try searching the forum in case your question has been answered previously. If that all yields nothing,
+ post a question to the forum.
+
+
+
+ If you want to keep up-to-date on RGraph, then subscribe to the group, as I post update notifications here. You can also follow me on
+ Twitter. I post update notifications here along with HTML5 related news.
+
+ 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.
+
+
+
+
Tooltips not working as of the October 2010 release
+
+
+ If you're specifying numbers instead of strings for your tooltips, they will not work any more. Simply cast them to
+ strings, like this:
+
+
+
+
+// This WILL NOT work any more
+myBar.Set('chart.tooltips', [56, 67, 53]);
+
+
+// Do any of these instead
+myBar.Set('chart.tooltips', ['56', (67).toString(), String(53)]);
+
+
+
+
Annotations aren't saved when running locally in Mozilla Firefox
+
+
+ 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.
+
+
+
+
Missing text in Google Chrome
+
+
+ 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.
+
+
+
+
Firefox, tooltips and the clipboard
+
+
+ Firefox, tooltips and using the clipboard is a little convoluted. To copy the text in a tooltip you must do the following:
+
+
+
+
Select the text you want with the mouse.
+
Press CTRL+C (it may be a different key combination if you're not using Windows) to copy the text to the clipboard.
+
+
+
+ Note: Recent versions of Firefox 4 (from beta 6 onwards) appear to work as expected, and you can copy text with the mouse as normal.
+
+
+
Shadows in Google Chrome and the line chart
+
+
+ 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.

RGraph: HTML5 canvas graph library - Examples of keys
+
+
+
+
+
+
+
+ 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.
+
+
+
+ The actual positioning is now configurable though, so you could have a horizontal key and position it to sit on top
+ of the chart.
+
+
+
Key properties
+
+
+ The available key properties and their defaults are listed below (some graph types have slightly different defaults to
+ suit):
+
+
+
+
+
chart.key ([] (An empty array))
+
chart.key.position (graph)
+
chart.key.position.gutter.boxed (true)
+
chart.key.position.x (null)
+
chart.key.position.y (null)
+
chart.key.shadow (false)
+
chart.key.shadow.offsetx (2)
+
chart.key.shadow.offsety (2)
+
chart.key.shadow.color (#666)
+
chart.key.shadow.blur (3)
+
chart.key.color.shape (square)
+
chart.key.background (white)
+
chart.key.rounded (true)
+
chart.key.text.size (10)

+ RGraph: HTML5 canvas graph library - Licensing FAQs
+
+
+
+
+
+
+
+
+
+
+
+
+
+
+
+
+ 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
+ here.
+
+
+
+
+
+
+ How much is a license?
+ A license is a one-time fee of £49 (UK pounds). That's roughly $70 (US dollars) at
+ the time of writing.
+
+
+
+
+
+ Where can I read the license?
+ The license is further down this page.
+
+
+
+
+
+ What does the license cover?
+ 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 phpguru.org.
+ 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.
+
+
+
+
+
+ Can you send me an invoice?
+ Of course, simply go here: http://www.rgraph.net/invoice.html, enter your email
+ address and you'll be sent an invoice that you can use for tax purposes.
+
+
+
+
+
+ Can I use PayPal?
+
+
+
+ Yes, you can use PayPal if you prefer. Please use the PayPal button shown here to start the process.
+
+
+
+
+
+
+
Contact
+
+ If you have a question about RGraph licensing, you can send it to licensing@rgraph.net
+ or you can order directly using Google Checkout.

+
+chart.tickmarks.dot.color
+ This is the color of the BORDER around the dot/borderedcircle style tickmarks. Default: #fff
+
+chart.stepped
+ Draws the line as stepped. Useful for showing stock performance for example. Default: false

+
+
+ chart.chromefix
+ Since version 6, Chrome has had a shadow bug, which becomes apparent when you use shadow blurring. This value defaults
+ to true and means that RGraph will skirt the bug with a small fix. Default: true
+
+
+
+
+
+
Methods
+
+
+ obj.getPoint()
+ This method makes it easier to get hold of which point on the Line chart has been hovered over. It returns an array of:
+
+
+
The graph object
+
The X coordinate
+
The Y coordinate
+
The numerical index of the point. This corresponds (for example) to the tooltips array, and the coordinates array
+
+
+ An example usage is:
+
+
+<canvas id="cvs" width="600" height="300">[No canvas support]</canvas>
+
+<script src="RGraph.common.core.js"></script>
+<script src="RGraph.line.js"></script>
+
+<script>
+ myGraph = new RGraph.Line('cvs', [10,4,2,4,1]);
+ myGraph.Set('chart.hmargin', 10);
+ myGraph.Set('chart.tickmarks', 'endcircle');
+ myGraph.Set('chart.labels', ['Fred','John','Kev','Lou','Pete']);
+ myGraph.Draw();
+
+
+ RGraph.Register(myGraph);
+
+ myGraph.canvas.onmousemove = function (e)
+ {
+ RGraph.FixEventObject(e);
+
+ var canvas = e.target;
+ var context = canvas.getContext('2d');
+ var obj = e.target.__object__;
+
+ // This is the new method which simplifies getting coordinates
+ var point = obj.getPoint(e);
+
+
+ if (point) {
+
+ canvas.style.cursor = 'pointer';
+
+ // Is this the same tooltip as the one (if any) that's already being shown
+ if (RGraph.Registry.Get('chart.tooltip') && RGraph.Registry.Get('chart.tooltip').__index__ == point[3]) {
+ return;
+ }
+
+ // Start afresh
+ RGraph.Redraw();
+
+ // Show the tooltip
+ RGraph.Tooltip(canvas, obj.Get('chart.labels')[point[3]], e.pageX, e.pageY, point[3]);
+
+ // Highlight the point
+ context.strokeStyle = 'gray';
+ context.fillStyle = 'white';
+ context.beginPath();
+ context.moveTo(point[1], point[2]);
+ context.arc(point[1], point[2], 2, 0, 6.26, 0);
+ context.stroke();
+ context.fill();
+
+ return;
+ }
+
+ canvas.style.cursor = 'default';
+ }
+
+ window.onclick = function ()
+ {
+ RGraph.Redraw();
+ }
+</script>
+
+
+
+
Combining the Line and Bar charts
+
+
+ You can combine the Bar and Line charts with a bit of magic. It's actually quite easy to do. Find out more here.
+ In the same vein, you can have Y axes on both the left and right.
+
+
+
+
+
Alternative colors
+
+
+ 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:
+
+ 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:
+
+
+
+<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>

Canvas fallback content and visually impaired users
+
+
+ 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 full canvas
+ zoom or the resizing feature to enable people to enlarge the graph.
+
+
+
+
+
Upper and lower limits for horizontal bars
+
+
+ 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:
+
+ 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:
+
+ 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.
+
+
+
+
+
RGraph and Microsoft Internet Explorer
+
+
+ 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 here.
+
+
+
+
+
Debugging tips
+
+
+ If you're having a hard time debugging your graph, try these:
+
+
+
+
Ensure you have only one graph on the page
+
Make sure you have disabled your web browsers cache (the Firefox Web Developer toolbar can do this for Firefox)
+
Try using Firebug (for Firefox) or the Webkit developer tools (for Google Chrome and Safari)
+
Reduce the page to the bare minimum.
+
Start with a very basic graph and build it up slowly.
+
+
+
+
+
+
+
Inspecting an RGraph graph
+
+
+ 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) here. To view these
+ tools in Google Chrome press CTRL+SHIFT+J. Inspect the canvas, and then the associated object can be found via
+ the __object__ property.
+
+
+
+
+
+
Double click context menus
+
+
+ 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.
+
+
+
+
+
+
Adding your own event handlers
+
+
+ Because each RGraph object exposes the canvas element (the same as what you get from document.getElementById()),
+ 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:
+
+
+
+<script>
+ var myBar = new RGraph.Bar('cvs', [7,4,2,6,3,4,8]);
+ myBar.Draw();
+
+ myBar.canvas.onclick = function ()
+ {
+ }
+</script>
+
+
+ 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 addEventListener(). This will add
+ your new event handler without replacing any existing one (ie the one installed by RGraph). For example:
+
+
+
+<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>
+
+
+
+
+
+
Carriage returns and newlines in labels
+
+
+ You can put carriage returns in your labels by using the string \r\n. This means your labels will span multiple lines.
+ Like so:
+
+ 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.
+
+
+
+
+
+
Character set issues
+
+
+ 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 header() function (which, as the
+ name suggests, sends a HTTP header):
+
+ If you use Apache, you could use the header directive, though this may be overridden by other directives,
+ eg AddDefaultCharset.
+
+
+
+
+
How to identify an RGraph object
+
+
+ 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:
+
+
+
+
obj.isRGraph - This is a boolean that you can use to clearly identify an RGraph object.
+
obj.type - 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.
+
+
+
+
+
+
+
+
+
+
+
+
+
+
+
+
+
+
+
+
Static Y axis
+
+
+
+
+ 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.
+
+
+
+ Note: 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.
+
+
+
+
+
+
+
+
+
+
+
+
+
+
Reducing white space
+
+
+
+
+
+
+ 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 translate(). 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.
+
+
+
+ Because the coordinate system is being changed things that rely on coordinates, eg tooltips, will be affected. For this reason
+ there is the property chart.tooltips.coords.adjust which you can use to tell RGraph that you've translated and the
+ tooltip coordinates will be adjusted appropriately.
+
+
+
+// This moves the graph to the right by 15px, and up by 15px. Do this before the call to .Draw()
+myObject.context.translate(15,-15);
+
+ You can read more information about this here.
+
+
+
+
+
Shorthand for in-graph labels
+
+ Instead of providing a full array of null elements for in-graph labels which may get a little unwieldy,
+ you can instead specify an integer that specifies how many elements to skip. Like this:
+
+ All the graphs have now (1st October 2010) been converted to DOM2 for tooltips event registration. This allows them to
+ be far more co-operative if you're using events. Tooltips will not be compatible with MSIE8 - the graphs will still be
+ drawn, albeit without tooltips.
+
+
+
+
+
+
+
+
+
Gutter suggestion function
+
+ RGraph now contains a function (RGraph.getGutterSuggest()) that will provide a simple suggestion for the gutter setting. This function is based on the
+ left gutter and labels and should be considered an approximate value.
+
+
+
+
+
+
+
+
+
Data types
+
+ If your data values aren't the correct type - ie numbers - it can cause problems. Pay particular attention to this
+ when you're getting your data from data sources which may be classed as strings, such as JSON or AJAX requests.
+
+
+
+
+
+
+
+
Creating your own Graph type
+
+ If you wish to create your own graph type, there is a skeleton file
+ here that you can use as a starting point.
+ This file contains the bare bones of an RGraph object, such as the .Get() and .Set() methods, as well as examples
+ of common properties.
+
RGraph: HTML5 canvas graph library - Microsoft Internet Explorer (MSIE) support
+
+
+
+
+
+
+ Microsoft Internet Explorer 9
+
+
+ Starting from preview 3, Internet Explorer 9 has support for canvas, including the text and shadow APIs. It also
+ benefits from hardware acceleration, and quick rendering times. You can see some screenshots
+ here.
+
+ 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
+ Google Chrome Frame to get the best results.
+ The interactive features are unlikely to work correctly. RGraph only works with Microsoft
+ Internet Explorer 8.
+
+
+
+ Thanks go to everyone involved with the ExCanvas project for providing the ExCanvas library.
+
+
+
+
Getting hold of ExCanvas
+
+
+ Google ExCanvas is distributed with RGraph in the "excanvas" directory. There is a minified gzip compressed version, along
+ with the original.
+
+
+
+
Caveats
+
+
+
The interactive features of RGraph are unlikely to work correctly with MSIE 8.
+
Shadows are now available (on some graph types), albeit without blurring.
+
You must reference the Javascript libraries in the documents <head>.
+
You must use the window.onload event to create your graph.
+
+ Inside the window.onload function your graph must be created as a local variable (ie you must use the var keyword). Eg:
+
+<script>
+ window.onload = function ()
+ {
+ var 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>
+
+
+
If your page is large, there may be a slight pause before the window.onload event fires and thus creates the graph.
+
Changing the font that text is shown in is not available.
+
+
+
+
Google Chrome Frame
+
+ 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.
+
+
+
+
+
+
+
+
Using a dynamically created canvas
+
+ If you're creating your canvas dynamically there is an extra step that you must perform to allow it to be recognised by
+ ExCanvas:
+
+chart.value.text
+ Controls whether the value is indicated as a text label in the center of the dial. Default: false
+
+chart.value.units.pre
+ The pre units used on the textual value. Default: nothing (An empty string)
+
+chart.value.units.post
+ The post units used on the textual value. Default: nothing (An empty string)
+
+chart.border
+ This controls the gray border of the Odometer. Default: false
+
+chart.tickmarks.highlighted
+ This controls whether the tickmarks are highlighted in red/yellow/green. Default: false
+
+chart.zerostart
+ If you want the top value on your chart to be zero instead of the maximum value, set this to true. Default: false
+
+
Margins
+chart.gutter
+ The width of the area outside the odometer. Default: 25
+
+
Colors
+chart.green.max
+ This is the point at which the green area ends. Default: 75% of the maximum value
+
+chart.red.min
+ This is the point at which the red area starts. The yellow area is between the green and red areas. Default: 90% of the maximum value
+
+
Labels and text
+chart.labels
+ Instead of using computed numbers, which uses the maximum value, you can specify the Odometer to use textual labels instead, with this option. Default: null
+
+chart.label.area
+ The width of the area that labels are put in. Default: 35
+
+chart.text.size
+ The size of the text (in points). Default: 10
+
+chart.text.font
+ The font used to render the text. Default: Verdana
+
+chart.text.color
+ The color of the labels. Default: black
+
+
Needle
+chart.needle.width
+ How thick the needle is. Default: 2
+
+chart.needle.color
+ The color that is applied to the needle. Default: black
+
+chart.needle.head
+ This controls whether the arrow head on the end of the needle is displayed. Default: true
+
+chart.needle.type
+ This determines which type of needle is used. It can be pointer or triangle. Default: pointer
+
+chart.needle.extra
+ With this you can specify a number of extra pointers that will be drawn on the Odometer. An example would be a meter that's used to show upload and download data. An example use:
+chart.title
+ The title text. Default: no title set
+
+
+chart.title.background
+The background color (if any) for the title.
+Default: null
+
+
+chart.title.color
+ The color of the title. Default: black
+
+chart.title.hpos
+ This allows you to completely override the horizontal positioning of the title. It should be a number between 0 and 1, and is multiplied with the whole width of the canvas and then used as the horizontal position. Default: null
+
+chart.title.vpos
+ This allows you to completely override the vertical positioning of the title. It should be a number between 0 and 1, and is multiplied with the gutter and then used as the vertical position. It can be useful if you need to have a large gutter. Default: null
+
+
Shadow
+chart.shadow.inner
+ Whether a drop shadow is applied to the inner circle of the Odometer Default: false
+
+chart.shadow.outer
+ Whether a drop shadow is applied to the whole Odometer. Default: false
+
+
Interactive features

+
+chart.annotatable
+ Whether annotations are enabled for the chart (ie you can draw on the chart interactively. Default: false
+
+chart.annotate.color
+ If you do not allow the use of the palette, then this will be the only colour allowed for annotations. Default: black
+
+chart.resizable
+ Defaulting to false, this determines whether your graph will be resizable. Because of the numerous event handlers this has to install code on, This feature is unlikely to work with other dynamic features (the context menu is fine however). Default: false
+
+
Zoom
+chart.zoom.mode
+ Can be used to control whether the zoom is in thumbnail or canvas mode. Possible values are: thumbnail and canvas. Default: canvas
+
+chart.zoom.factor
+ This is the factor that the graph will be zoomed by (bigger values means more zoom) Default: 1.5
+

RGraph: HTML5 canvas graph library - Retrieving a PNG of your graph
+
+
+
+
+
+
+ Get PNG
+
+
+
+
+
+ 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.
+
+
+
+ Originally, the function was designed to be used with a context menu, so it is located in the RGraph.common.context.js.
+ 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 Tradar example.
+
+ 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.
+
+
+
+<!-- This CSS positions the link over the top right of the canvas -->
+<style>
+ span#png_link {
+ position: absolute;
+ left: 450px;
+ top: 30px;
+ border: 1px black solid;
+ padding: 1px;
+ background-color: #eee;
+ cursor: pointer;
+ }
+</style>
+
+<div style="position: relative">
+ <span id="png_link" onclick="RGraph.showPNG(myCanvas, event)">Get PNG</span>
+ <canvas id="cvs" width="600" height="250">[No canvas support]</canvas>
+</div>
+
RGraph: HTML5 canvas graph library - Resizing your graphs
+
+
+
+
+
+
+
+
+ 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.
+
+
+
+ All you need to do to enable it is set chart.resizable to true. There are certain caveats that you should be aware of though:
+
+
+
+
+
+
+ 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.
+
+
+
+ The minimum you can resize your graphs to is 50% of the original graph width/height.
+
+
+
+ Note: 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.
+
+
+
+ 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.
+

+
+
+
Lower whisker
+
Bottom of box
+
Middle value (which isn't necessarily in the center of the box - this depends on your data)
+ 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:
+
+ 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:
+
+
+
+<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

+ */
+ function myTick (obj, data, x, y, xVal, yVal, xMax, yMax, color)
+ {
+ // Draw your custom tick here
+ }
+</script>
+
+
+
+
Note about colors and the key
+
+
+ If you're using a key you may need to set chart.line.colors to allow it to use the correct colors. For example:
+
RGraph: HTML5 canvas graph library - The RGraph.SetConfig() function
+
+
+
+
+
+ A graph showing RGraph.SetConfig()
+
+
+
+
+
+
+ Instead of using a number of .Set() calls, you may find that using the RGraph.SetConfig() method more to your tastes. The
+ method is an alternative to setting the configuration of your graph. It can also facilitate reuse better, so that the
+ appearance of all of your websites charts is the same. There's an example of its use below:
+
+
+
+
+
+<script>
+ window.onload = function ()
+ {
+ /**
+ * This configuration could be stored in a central configuration file, making its reuse easier. You could also have
+ * several different configurations that you pick and choose from depending on the requirements. Values in
+ * subsequent calls to .SetConfig() will overwrite previous ones.
+ */
+ var config = {
+ 'chart.colors': ['red', 'green'],
+ 'chart.labels': ['John','Fred','June','Charles','Lou', 'Olga'],
+ 'chart.title.yaxis': 'Amount',
+ 'chart.title.yaxis.pos': -0.2,
+ 'chart.title.xaxis': 'Person',
+ 'chart.background.grid.autofit': true
+ }
+ var bar = new RGraph.Bar('cvs', [48,56,52,49,43,51]);
+ RGraph.SetConfig(bar, config);
+ bar.context.translate(20,-20);
+ bar.Draw();
+ }
+</script>
+
+ Tooltips are a very effective and straight forward way to extend your graphs and add more information to them, without overloading
+ the user.
+
+
+
+
What can they hold?
+
+
+ At the base level, tooltips are DIVs, so they can hold a multitude of HTML - images, videos etc. See below
+ for information on showing graphs in tooltips.
+
+
+
+
How can I specify them?
+
+
+ You can specify them by including the tooltips code and then using the chart.tooltips property. For example:
+
+ 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:
+
+
+
+
+ An array of strings. The string is used as the tooltip. Eg:
+
+ 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 before
+ 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 CSS class or a call to setTimeout(). Eg:
+
myGraph.Set('chart.tooltips', getTooltip);
+
+
+
+ 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 display CSS value to none. An example of this in action is the
+ first line chart. For example:
+
+
myBar.Set('chart.tooltips', ['id:myDiv', ...])
+
+
+
+
+
Can I show graphs in tooltips?
+
+
+
+
+ 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 ontooltip 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:
+
+
+
+
Specify the HTML for the tooltip as normal (including the <canvas> tag).
+
Use the ontooltip RGraph event so that a function is called when a tooltip is shown.
+
This function should subsequently create the graph.
+
+
+
+ The tooltip DIV is to be found in the RGraph registry - RGraph.Registry.Get('chart.tooltip'). And if you want it the
+ numerical zero indexed count of the tooltip is to be found in the __index__ property:
+ RGraph.Registry.Get('chart.tooltip').__index__

+
+
+ 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.
+
+
+
+
+
+
Can I customise the appearance of tooltips?
+
+
+ Yes. You can either use the default CSS class RGraph_tooltip, or you can specify a specific CSS class that a
+ graphs tooltips should use with the property chart.tooltips.css.class. 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 bar_chart_tooltips_css. For example:
+
+ You can read more about RGraph CSS classes here.
+
+
+
+
What tooltip effects are available?
+
+
+ These effects are available to you:
+
+
+
+
fade
+
expand
+
contract
+
snap
+
none
+
+
+
+ All of them are as their names imply. fade is a straight forward fade in effect, expand is another effect
+ which expands outward from the center of the tooltip, contract is like the expand effect but in reverse, snap is an effect which can be used in a limited set of circumstances
+ and "snaps" to the current mouse position and none is simply no effect at all. The default effect used
+ by all graph types is fade. Note: If you're showing canvases in your tooltips then the expand, contract and snap
+ effects will not work - you must use fade or none.
+
+
+
+ Note: The snap effect is only available to graph types where the tooltip is triggered using the onmousemove event.
+ Currently this means the Line chart, Rscatter graph, Scatter graph and Tradar chart. It can also
+ be negatively effected when using multiple graphs on one page.
+
+
+
+
+
Tooltips, the clipboard and Firefox
+
+
+ If you're using Firefox, there's a note about tooltips and the clipboard (ie copying text) on the issues page.
+
+
+
+
Can I override the tooltip function?
+
+
+ You can by stipulating chart.tooltips.override. 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:
+
+
+
+
canvas - The HTML canvas element, the same as what you get from document.getElementById()
+
text - The tooltip text (id:xxx strings are NOT expanded)
+
x - The X coordinate in relation to the entire page
+
y - The Y coordinate in relation to the entire page
+
index - The numerical index of the tooltip in the original tooltip array
+
+
+
+ Note: Although "id:xxx" strings are not expanded for you, you can easily do this yourself by using the
+ RGraph.getTooltipText('id:xxx') function.

+chart.zoom.background
+ Defaulting to true, this determines whether the zoom has a dark, semi-opaque background that covers the entire web page. Default: true
+ As of November 2009 RGraph has had the ability to provide a zoom facility. It's designed to be used in
+ conjunction with a context menu as in the example to the right.
+
+
+
+ You can control the zoom using these properties:
+
+
+
+
chart.zoom.modeDefault: canvas
+
chart.zoom.factorDefault: 1.5
+
chart.zoom.fade.in Default: true
+
chart.zoom.fade.out Default: true
+
chart.zoom.hdir Default: right
+
chart.zoom.vdir Default: down
+
chart.zoom.delay Default: 50
+
chart.zoom.frames Default: 10
+
chart.zoom.shadow Default: true
+
chart.zoom.mode Default: canvas
+
chart.zoom.thumbnail.width Default: 75
+
chart.zoom.thumbnail.height Default: 75
+
chart.zoom.background Default: true
+
+
+
+
+
+
+
+
+
+
+ The possible values of chart.zoom.hdir are: left, center, right.
+ The possible values of chart.zoom.vdir are: up, center, down. chart.zoom.delay
+ is the delay in between frames (in milliseconds) and chart.zoom.frames is the number of frames in the zoom. chart.zoom.shadow
+ is whether the zoomed canvas has a shadow or not. The possible values of chart.zoom.mode are canvas (default)
+ and thumbnail.
+
+ The zoom has an alternative thumbnail mode, which displays a small thumbnail zoom instead of zooming the entire canvas.
+ The graph to the left shows an example of this.
+
+
+
+ It uses some of the same properties as the regular zoom, eg chart.fade.in, chart.fade.out, chart.zoom.shadow
+
+
+ It is possible to make the zoom in area mode circular by utilising the border-radius 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:
+
+
+
+<style>
+ .RGraph_zoom_window {
+ border-radius: 50px ! important;
+ }
+</style>
+
+
+ This a graph demonstrating this technique here. Note that browser support for this technique is limited.
+
+
+
+
+
+
Area mode
+
+
+
+
+ Another type of zoom available is area. This is somewhat similar to thumbnail, but allows you to draw a rectangle around
+ the specific area that you want to zoom.
+
+
+
+ Again, this uses some common zoom properties, such as chart.zoom.factor.
+
+
+
+ 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.
+
+
+
+
+
+<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');
+ myLine.Set('chart.hmargin', 10);
+ myLine.Set('chart.linewidth', 1);
+ myLine.Set('chart.title', 'A graph with zoom in area mode');
+ myLine.Set('chart.tickmarks', 'endcircle');

+ 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.
+
+
+
+ By using the tooltips feature, you can provide more detail about what a particular bar represents. The tooltips in
+ RGraph can contain wide range of HTML, so you can use them to show photos or movies for example.

RGraph: HTML5 canvas graph library - A basic example
+
+
+
+
+
+
+
+
+ This is a very basic example that does little more than display a graph. If you're trying to understand how RGraph
+ works, this should help as there is very little happening on this page. To see the source code of this
+ page simply view the source (Right click > View Source).
+
+ The Bi-polar chart is also (possibly more commonly) known as an age-frequency chart or a population pyramid. It allows you to very straight forwardly
+ compare two sets of data. For example two years worth of sales figues. Using this type of chart abnormalities will become
+ apparent. Other charts that would also be comparable, include a grouped bar chart, a stacked bar chart, and a multiple
+ line graph.
+
+ Formerly the Donut chart was a separate class, though now it's a variant of the Pie chart. This means smaller downloads and
+ a much simpler implementation. Essentially it's a Pie chart with a big hole in the middle. If you want to compare multiple
+ datasets you will probably be better off with something like a stacked or grouped bar chart, as you will be able to make
+ comparisons easier.
+
+ The funnel chart can be used to show stages in a sales or order process, from initial lead/contact through to actual sale.
+ It works well if you have a diminishing process, like that shown below. It can show potential revenue in each stage, or
+ like below, it can show actual numbers. It can also highlight potential problems in an organisations sales and/or order fulfillment
+ processes.
+
+ 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.
+
+
+
+ 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.
+
RGraph: HTML5 canvas graph library - Horizontal Progress bar
+
+
+
+
+ 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 RGraph.Clear()
+ (which clears the canvas) and then call myProgress.Draw() again.
+
+
+
+ The colours, title and scale are configurable, allowing you to represent a wide range of values.
+
+ An LED grid, that could be used to show a multitude of things. Could be used as a website counter for example.
+ It supports the A-Z, 0-9 and space characters. As you can see the colors are also user-definable. It also
+ supports the context menu, and therefore the zoom. The first LED grid demonstrates this.
+
+ 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.
+
+
+
+ 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 Meter is similar to the Odometer albeit only a semi-circle and not a full circle. It can be better when trying illustrate
+ a particular level, but only have a limited amount of space. It could also be quite effective as part of a control panel.
+
+ The Odometer can be used to provide an indication of a particular value. For example you could easily use it to
+ represent values for a control panel that shows information about a server. An Odometer indicating how much disk
+ space is used for example, would be more visual than a simple number.
+
+
+
+ The green, yellow and red areas are configurable, allowing you to add some level of urgency into your figures. The
+ figures are also configurable, so it can go from 0-10, or from 0-100.
+
+ 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.
+
+
+
+ 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.
+
+
+
+ The first pie chart has a fade-in effect. This not part of the RGraph library but is very easy to implement.
+
+ The Radial scatter chart is a circular variant of the regular Scatter chart, and as the name suggests, circular. It
+ may be more suited to your dataset than the regular scatter chart.
+
+ 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.
+
RGraph: A text function that does horizontal and vertical alignment (and spins)
+
+
+
+
+
+
+
+
+
+
+
+
+
+
+
+
+
+
+ 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... Reset the page
+
+
+
+ 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>!
+
+
+
+ More examples can be found on the individual example pages, and a more complete
+ reference to the Text() function can be found in the API docs.

RGraph: HTML5 canvas graph library - Traditional radar chart
+
+
+
+
+
+
+
+ A traditional radar chart, that is similar to the Rose chart. Each of the data points is
+ arranged equally in terms of angle, whilst the magnitude of each point is shown by the distance from the centre. Thus,
+ data points of a higher magnitude can be seen as they are more distant from the centre.
+
+
+
+ Suitable for many datasets, but not all. If not, then the Rose chart may be more apt.
+
+
+
+ The circle, as can be seen in the second example, could be used to indicate a threshold of sorts. In the example,
+ it could be minimum sales required for a particular month. Months that fall below this threshold can be clearly seen.
