A Line chart with a custom line

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="800" height="250">
    [No canvas support]
</canvas>

This is the code that generates the chart:

<script>
    window.onload = function ()
    {
        var color = '#E9B34E';
        
        var line = new RGraph.Line({
            id: 'cvs',
            data: [

                [null,null,null,null,null,null,null,28500,11000,14000,9000,10000],
