A Pie chart using the CSV reader

Note: For browser security reasons the AJAX demos don't work offline. You can view the demos on the RGraph website here: https://www.rgraph.net/demos/index.html

This goes in the documents header:

<script src="RGraph.common.core.js"></script>
<script src="RGraph.common.csv.js"></script>
<script src="RGraph.pie.js"></script>

Put this where you want the chart to show up:

<canvas id="cvs" width="500" height="250">
    [No canvas support]
</canvas>

This is the code that generates the chart:

<script>
    window.onload = function ()
    {
        new RGraph.CSV('/sample.csv', function (csv)
        {
            // Fetch the labels from the CSV file (the first column)
            var labels = csv.getCol(0);

            // Fetch the second column of the CSV file
            var data = csv.getCol(1);

            var pie = new RGraph.Pie({
                id: 'cvs',
                data: data,
                options: {
                    labels: labels,
                    exploded: 5,
                    textAccessible: true,
                    labelsSticksList: true,
                    labelsSticksColors: [
                        'red','gray',
                        'green','blue',
                        'pink','#aa0'
                    ]
                }
            }).draw();
        });
    };
</script>
