[No canvas support]

This goes in the documents header:
<script src="RGraph.common.core.js"></script>
<script src="RGraph.common.dynamic.js"></script>
<script src="RGraph.common.tooltips.js"></script>
<script src="RGraph.common.effects.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]
This is the code that generates the chart:
    new RGraph.Waterfall({
        id: 'cvs',
        data: [50,12,-50,-19, -130, -30],
        options: {

            backgroundGridVlines: false,
            backgroundGridBorder: false,
            title: 'A chart showing income/expenditure',

            colors: ['black','red','blue'],

            total: true,
            xaxisLabels: ['Sales', 'Misc', 'Wages','Fees','Supplies','Food','Gross'],
            tooltips: [

            highlightStroke: 'rgba(0,0,0,0)',                
            // In older versions of Firefox this seriously slows down the grow() animation
            shadowColor: '#aaa',
            shadowBlur: 5,
            shadowOffsetx: 0,
