# A Bipolar 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: http://www.rgraph.net/demos

This goes in the documents header:

    <script src="RGraph.common.core.js"></script>
    <script src="RGraph.common.csv.js"></script>
    <script src="RGraph.bipolar.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 first three columns to use as labels and the left/right data
                var labels = csv.getCol(0);
                var left   = csv.getCol(1);
                var right  = csv.getCol(2);

                var bipolar = new RGraph.Bipolar({
                    id: 'cvs',
                    left: left,
                    right: right,
                    options: {
                        textAccessible: true,
                        labels:  labels
                    }
                }).draw();
            });
        };
    </script>
