A dark and graduated blue Bar chart

A dark and graduated Bar chart. The colors are black at the bottom of the bars graduating to blue towards the top. The background grid is customised too with the horizontal gridlines having been disabled. Nor are there any labels. The chart uses the grow() effect (as you can see!).

Another thing to note here is the complete lack of an labels on the chart. You don't always need to have labels as the meaning of the chart may be clear without them - perhaps having a title elsewhere on the page. I wouldn't imagine that these use cases are very common though - with most charts requiring at least a scale in order to make sense.

This goes in the documents header:
<script src="RGraph.svg.common.core.js"></script>
<script src="RGraph.svg.bar.js"></script>
Put this where you want the chart to show up:
<div style="width: 600px; height: 300px" id="chart-container"></div>
This is the code that generates the chart:
<script>
    data = [6,4,5,5,7,4,8];

    var bar = new RGraph.SVG.Bar({
        id: 'chart-container',
        data: data,
        options: {
            hmargin:15,
            xaxis: false,
            yaxis: false,
            yaxisLabels: false,
            backgroundGridColor: '#999',
            backgroundGridHlines: false,
            backgroundGridBorder: false,
            colors: ['Gradient(#6969FF:#6969FF:#000)']
        }
    }).wave();
</script>
