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

190     
191     
192     <b>How much is a license?</b><br /><br />
193     A license is a one-time fee of <b>&pound;49</b> (UK pounds). That's roughly $70 (US dollars) at
194     the time of writing.

198     <p>&nbsp;</p>
199     
200     <b>Where can I read the license?</b><br /><br />
201     The license is further down this page.

205     <a name="cover"></a>
206     <p>&nbsp;</p>
207     <b>What does the license cover?</b><br /><br />
208     The RGraph license covers RGraph as a whole. Excepting ExCanvas, all code that you find in the RGraph archive is
209     covered by the RGraph license. The license also covers code that I've written that is available from <a href="http://www.phpguru.org" target="_blank">phpguru.org</a>.
210     This is a mainly
211     PHP focused website, but also plays host to a fair amount of Javascript too. So if your development language of choice is not PHP,
212     you may still find something of use there.<br /><br />

219     Of course, simply go here: <a href="http://www.rgraph.net/invoice.html">http://www.rgraph.net/invoice.html</a>, enter your email
220     address and you'll be sent an invoice that you can use for tax purposes.
