A filled spline chart with a max value

This goes in the documents header:

<script src="RGraph.common.core.js"></script>
<script src="RGraph.line.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 = [30,29,24,25,26,24,23,22,21,18,19,17,20,23,24, 24,26,27,29,30];
        var data2 = [1,3,2,1,2,3,3,2,4,1,2,3,2,1,2,4,3,5,3,2];
        var data3 = [10,13,12,15,16,19,14,15,16,18,20,18,16,18,17,19,20,22,23,23];
        var data4 = [3,5,7,8,4,6,5,4,3,1,2,4,5,2,1,3,4,6,2,4];
        
        // Make the last dataset equal to 65
        var data5 = [], i = data1.length; while(i--) {
            data5[i] = 65 - (data1[i] + data2[i] + data3[i] + data4[i]);
        }

        var obj = new RGraph.Line({
            id: 'cvs',
            data: [data1, data2, data3, data4, data5],
            options: {
                linewidth: 0,
                filled: true,
                spline: !RGraph.ISOLD,
                colors: ['red','yellow','#0d0','yellow','red'],
                strokestyle: 'rgba(0,0,0,0)',
                shadow: false,
                numxticks: 4,
                ymax: 65,
                noyaxis: true,
                labels: [
                    '','','','Monday','','',
                    '','','','Tuesday','','',
                    '','','','Wednesday','','',
                    '','','','Thursday','',''
                ],
                tickmarks: null,
                textSize:14,
                scaleZerostart: true,
                textAccessible: true
            }
        }).draw();
    };
</script>
