This goes in the documents header:
<script src="RGraph.common.core.js"></script>
<script src="RGraph.bipolar.js"></script>
Put this where you want the chart to show up:
<canvas id="cvs" width="600" height="250">

This is the code that generates the chart:
    left = [4,8,6,3,1,20,5];
    right = [15,13,18,19,12,16,14];

    bar = new RGraph.Bipolar({
        id: 'cvs',
        left: left,
        right: right,
        options: {
            titleLeft: 'August 2013',
            titleRight: 'August 2014',
