var line = new RGraph.Line({

This goes in the documents header:
<pre class="code">
<script src="RGraph.common.core.js"></script>
<script src="RGraph.common.dynamic.js"></script>
<script src="RGraph.common.tooltips.js"></script>
<script src="RGraph.drawing.circle.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>
var line = new RGraph.Line({
id: 'cvs',
data: [5,8,6,4,3,5,2],
options: {
hmargin: 5,
labels: ['Monday','Tuesday','Wednesday','Thursday','Friday','Saturday','Sunday'],
textAccessible: true
}
}).draw();
var coords = line.coords[2];
var circle = new RGraph.Drawing.Circle({
id: 'cvs',
x: coords[0],
y: coords[1],
radius: 30,
options: {
strokestyle: 'rgba(0,0,0,1)',
fillstyle: 'rgba(0,0,0,0.2)'
}
}).on('click', function (e, shape)
{
alert('[RGRAPH] The circle has been clicked!');
}).on('mousemove', function (e, shape)
{
return true;
}).draw();
</script>
</pre>
