A Line chart with different colors for up/down

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 line = new RGraph.Line({
            id: 'cvs',
            data: [5,4,7,6,8,5,9],
            options: {
                labels: ['Monday','Tuesday','Wednesday','Thursday','Friday','Saturday','Sunday'],
                linewidth: 2,
                colors: [['red','black']],
                colorsAlternate: true,
                textAccessible: true
            }
        }).draw();
    };
</script>
