Bipolar chart Grow effect

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>
    window.onload = function ()
    {
        var left  = [4,8,6,3,1,2,5];
        var right = [15,13,18,19,12,16,14];

        var bar = new RGraph.Bipolar({
            id: 'cvs',
            left: left,
            right: right,
            options: {
                gutterCenter: 135,
                titleLeft: 'August 2013',
                titleRight: 'August 2014',
                textColor: '#666',
                textSize: 16,
                labels: ['Monday','Tuesday','Wednesday','Thursday','Friday','Saturday','Sunday'],
                colors: ['gradient(red:red:red:red:#c00:#c00:#c00:red:red:red:red)'],
                textAccessible: true
            }
        }).grow();
    };
</script>
