# A stacked Bar chart showing income/expenditure

This goes in the documents header:

    <script src="RGraph.common.core.js"></script>
    <script src="RGraph.bar.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 data1 = [[2,5,9],[4,2,6],[6,5,8]];
            var data2 = [-4,-5,-20];

            // Top bar chart
            var bar1 = new RGraph.Bar({
                id: 'cvs',
                data: data1,
                options: {
                    shadow: false,
                    strokestyle: 'rgba(0,0,0,0)',
                    noaxes: true,
                    ylabels: false,
                    colors: ['blue','pink','aqua'],
                    hmargin: 25,
                    strokestyle: 'rgba(0,0,0,0)',
                    backgroundGrid: false,
                    gutterBottom: 125,
                    grouping: 'stacked',
                    ymax: 20,
                    textAccessible: true
                }
            }).wave()

            // Bottom bar chart
            var bar2 = new RGraph.Bar({
                id: 'cvs',
                data: data2,
                options: {
                    shadow: false,
                    colors: ['red'],
                    hmargin: 25,
                    xaxispos: 'center',
                    backgroundGrid: false,
                    ymax: 20,
                    textAccessible: true
                }
            }).wave()
        };
    </script>
