A Bar chart using AJAX

Here is an example of a 3D variation of the Bar chart which is both animated using the grow effect and which is also fetching its data via ajax.

The ajax script is a simple one that just outputs a sequence of random numbers. You can see the script directly by going here.

If you view the ajax script you'll see that it just outputs the numbers and nothing else - so no labels or title. So on the chart, the labels are just hardcoded.

The rest of the configuration is pretty straightforward - and you can see it below.

When the screen is smaller the canvas dimensions are reduced, the marginInner is reduced and the textSize is reduced as well.

This goes in the documents header:

<script src="RGraph.common.core.js"></script>
<script src="RGraph.common.dynamic.js"></script>
<script src="RGraph.common.tooltips.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>
    // Use the RGraph.AJAX.getCSV() function to fetch some CSV data from the server.
    // This example fetches the URL https://www.rgraph.net/getdata.html which just
    // outputs a set of CSV values. The second argument is a function which is
    // used as the callback and creates the chart.
    RGraph.AJAX.getCSV('/getdata.html', function (data)
    {
        new RGraph.Bar({
            id: 'cvs',
            
            // Use the CSV data directly in the chart configuration
            data: data,

            options: {
                colors: ['gradient(#080:green)'],
                xaxisLabels: ['John', 'Fred', 'Joe', 'Rich', 'Pete', 'Lilly', 'Fred', 'Joe', 'Rich', 'Pete'],
                marginLeft: 35,
                
                // This sets it so that the bar chart is drawn as a 3D variant
                variant: '3d',

                // 3D Bar charts look better with a transparent stroke color
                colorsStroke: 'transparent',

                marginInnerGrouped: true,
                backgroundGridVlines: false,
                backgroundGridBorder: false,
                shadowOffsetx: 10,
                marginBottom: 75,
                xaxis: false,
                yaxis: false,
                
                tooltips: '<span style="font-size: 14pt">Total value:<br /><span style="font-size: 26pt">%{value}%',

                title: 'An animated 3D Bar chart',
                titleColor: '#666',
                titleBold: true,
                titleSize: 16,
                titleOffsety: 5,
                titleSubtitle: 'This chart uses random data',
                titleSubtitleOffsety: -5,
                responsive: [
                    {maxWidth: null,width:600,height:250,options:{marginInner: 10,textSize:12},parentCss:{'float': 'right',textAlign:'none'}},
                    {maxWidth: 800,width:400,height:200,options:{marginInner: 5,textSize:10},parentCss:{'float': 'none',textAlign:'center'}}
                ]
            }
        
        // The grow() animation effect is used and works just like a regular Bar chart. Some
        // responsive capability is also added.
        }).grow();
    });
</script>
