A line chart with different linewidths

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="900" height="250">
    [No canvas support]
</canvas>

This is the code that generates the chart:

<script>
    window.onload = function ()
    {
        var line = new RGraph.Line({
            id: 'cvs',
            data: [
                [31,25,23,41,35,36,56,66,46,13,32,41],
                [45,12,83,53,52,54,12,32,65,98,87,86]
            ],
            options: {
                fillstyle: 'rgba(255,0,0,0.3)',
                colors: ['gray', 'green'],
                linewidth: [7, 3],
                title: 'Multiple lines with differing line widths',
                key: ['Thursday', 'Wednesday'],
                keyBackground: 'rgba(255,255,255,0.8)',
                keyRounded: true,
                labels: ['Jobe', 'Violet', 'Olga', 'Kev', 'Bob', 'Lynn', 'Pete', 'Lou', 'John', 'Hope', 'Fred', 'John'],
                shadowOffsetx: 0,
                shadowOffsety: 0,
                shadowBlur: 15,
                shadowColor: ['gray','green'],
                noaxes: true,
                yaxispos: 'right',
                gutterLeft: 5,
                gutterRight: 35,
                gutterTop: 35,
                gutterBottom: 35,
                textAccessible: true
            }
        }).draw();
    };
</script>
