An adjustable Bar chart

Here's a basic Bar chart that only has one configuration option specified: adjustable This means that the chart can be adjusted dynamically by clicking on the chart and moving your mouse up and down. The types of charts that can be adjusted are:

• Bar charts
• Fuel charts
• Gantt charts
• Gauge charts
• Horizontal Bar charts
• Horizontal Progress bars
• Line charts (including spline charts)
• Meter charts
• Odometer charts
• Semi-circular Progress bars
• Thermometer charts
• Vertical Progress bars
• SVG Gauge

You can read more about adjusting and see the canvas documentation for it here.

When the browser/screen is smaller the size of the canvas is reduced, the textSize is reduced and the CSS float on the container is removed.

This goes in the documents header:

<script src="RGraph.common.core.js"></script>
<script src="RGraph.common.dynamic.js"></script>
<script src="RGraph.bar.js"></script>

Put this where you want the chart to show up:

<div style="float: right">
    <canvas id="cvs" width="600" height="250">[No canvas support]</canvas>
</div>

This is the code that generates the chart - it should be placed AFTER the canvas tag(s):

<script>
    // Quite a basic Bar chart which just has the single 'adjustable'
    // property being stipulated meaning that you dynamically adjust
    // the chart
    new RGraph.Bar({
        id: 'cvs',
        data: [8,6,4,8,9,5,3,2,5],
        options: {
            title: 'An adjustable Bar chart',
            titleBold: true,
            titleSize: 16,
            adjustable: true,
            xaxisLabels: ['Alf','Vinny','Moe','Bill','Neil','Olga','Lilly','Paul','John']
        }
    }).draw().responsive([
        {maxWidth: null,width: 600,height: 250,options:{textSize:16},parentCss: {'float':'right'}},
        {maxWidth: 800,width: 350,height: 200,options:{textSize:10},parentCss: {'float':'none', textAlign: 'center'}}
    ]);
</script>
