A basic Bipolar chart

[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="350">
    [No canvas support]
</canvas>
This is the code that generates the chart:
<script>
    new RGraph.Bipolar({
        id: 'cvs',
        left: [8,4,6,5,2,5,8],
        right: [4,8,6,3,9,5,2],
        options: {
            axes: false,
            colors: ['gradient(red:white:red)'],
            yaxisLabels: ['Monday','Tuesday','Wednesday','Thursday','Friday','Saturday','Sunday'],
            tooltips: [
                'John','Luke','Pete','Jane','Fred','Kim','Lula',
                'John','Luke','Pete','Jane','Fred','Kim','Lula'
            ]
        }
    }).draw();
</script>
