A Line chart with background horizontal bars

[No canvas support]

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]
This is the code that generates the chart:
    line = new RGraph.Line({
        id: 'cvs',
        data: [26,4,-15.5,17,42.5,25],
        options: {
            xaxisLabels: ['2007', '2008', '2009', '2010', '2011', '2012'],
            backgroundHbars: [
            xaxisPosition: 'center',
            yaxisScaleMax: 60,
            linewidth: 5,
            hmargin: 5,
            colors: ['black']
