A stacked, spline line chart

This goes in the documents header:

<script src="RGraph.common.core.js"></script>
<script src="RGraph.common.key.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 mline = new RGraph.Line({
            id: 'cvs',
            data: [
                [4,6,12,16,8,4,2,8,18,16,14,16],
                [2,4,8,4,2,6,6,12,8,10,6,8],
                [1,3.5,5,3,4,5,6,11,8,9,5,7]
            ],
            options: {
                labels: ['Jan','Feb','Mar','Apr','May','Jun','Jul','Aug','Sep','Oct','Nov','Dec'],
                gutterLeft: 40,
                gutterTop: 35,

                fillstyle: ['Gradient(white:red)', 'Gradient(white:blue)', 'Gradient(white:green)'],
                unitsPost: '%',
                linewidth: 0.25,
                spline: !RGraph.ISOLD,
                title: 'Robert, Daniel and Janices stats',
                titleVpos: 0.5,
                textColor: '#333',
                textFont: 'Arial',
                key: ['Robert', 'Daniel', 'Janice'],
                keyColors: ['red', 'blue', 'green'],

                keyPositionX: 50,
                shadowOffsety: 2,
                shadowBlur: 5,
                tickmarks: null,
                backgroundGridAutofitNumvlines: 11,
                numxticks: 11,
                textAccessible: true
            }
        }).on('beforedraw', function (obj)
        {
            RGraph.clear(obj.canvas, 'white');
        })
        .draw()
        .trace2({frames: 60});
    };
