custom RGraph event.

This goes in the documents header:
<pre class="code">
<script src="RGraph.common.core.js"></script>
<script src="RGraph.line.js"></script>
</pre>
Put this where you want the chart to show up:
<pre class="code">
<canvas id="cvs" width="600" height="250">
[No canvas support]
</canvas>
</pre>
This is the code that generates the chart:
<pre class="code">
<script>
window.onload = function ()
{
var line = new RGraph.Line({
id: 'cvs',
data: [28,21,26,32,35,36,39,45,47,51,55,74,85],
options: {
