A Line chart with different linewidths

[No canvas support]

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>
    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: {
            filledColors: 'rgba(255,0,0,0.3)',
            colors: ['gray', 'green'],
            linewidth: [7, 3],
            title: 'Multiple lines with different linewidths',
            titleSize: 16,
            titleBold: true,
            key: ['Thursday', 'Wednesday'],
            keyBackground: 'rgba(255,255,255,0.8)',
            keyRounded: false,
            xaxisLabels: ['Jobe', 'Violet', 'Olga', 'Kev', 'Bob', 'Lynn', 'Pete', 'Lou', 'John', 'Hope', 'Fred', 'John'],
            shadowOffsetx: 0,
            shadowOffsety: 0,
            shadowBlur: 15,
            shadowColor: ['gray','green'],
            axes: false,
            yaxisPosition: 'right',
            marginLeft: 5,
            marginRight: 35,
            marginTop: 35,
            marginBottom: 35
        }
    }).draw();
