A basic Waterfall chart

[No canvas support]

This goes in the documents header:
<script src="RGraph.common.core.js"></script>
<script src="RGraph.waterfall.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>
    new RGraph.Waterfall({
        id: 'cvs',
        data: [10,10,5,-2,-15,6,-5],
        options: {
            xaxisLabels: ['Monday', 'Tuesday', 'Wednesday', 'Thursday', 'Friday', 'Saturday', 'Sunday', 'Total'],
            axes: false,
            backgroundGridVlines: false,
            backgroundGridBorder: false,
            colorsStroke: 'rgba(0,0,0,0)'
        }
    }).draw();
</script>
