Bipolar chart wave() effect

[No canvas support]

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">
    [No canvas support]
</canvas>
This is the code that generates the chart:
<script>
    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',
            textSize: 16,
            textColor: '#666',
            yaxisLabels: ['Monday','Tuesday','Wednesday','Thursday','Friday','Saturday','Sunday'],
            colors: ['gradient(red:red:red:red:#fcc:#fcc:#fcc:red:red:red:red)'],
            axes: false
        }
    }).wave();
</script>
