A Bar chart with a dark background

This is a grouped Bar chart, with two bars per group, which uses a red/blue graduated fill. The background grid has been customised and the background itself is a dark color (so the text has been changed to white). Also the chart is using the Bar chart wave() effect. This grows sequentially from the left hand side with a small delay between each group of bars.

[No canvas support]

This goes in the documents header:

<script src="RGraph.common.core.js"></script>
<script src="RGraph.bar.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 data = [[45,56],[75,32],[39,47],[34,48],[46,47],[48,52]];

        new RGraph.Bar({
            id: 'cvs',
            data: data,
            options: {
                shadow: false,
                strokestyle: 'rgba(0,0,0,0)',
                grouping: 'grouped',
                colors: ['Gradient(white:#ccf:#ccf:#ccf:#ccf)','Gradient(white:#faa:#faa:#faa:#faa)'],
                backgroundGridVlines: false,
                backgroundGridBorder: false,
                textColor: 'white',
                labels: ['2007','2008','2009','2011','2012','2013'],
                textAccessible: true,
                textSize: 16,
                gutterLeft: 35,
                gutterBottom: 35,
                gutterTop: 15,
                gutterRight: 5
            }
        }).wave();
    };
</script>
