A RScatter 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.rscatter.js"></script>

Put this where you want the chart to show up:

<canvas id="cvs" width="500" height="450">
    [No canvas support]
</canvas>

This is the code that generates the chart:

<script>
    window.onload = function ()
    {
        new RGraph.CSV('/sample.csv', function (csv)
        {
            // Just fetch the two rows of the CSV file, starting at the second column
            var row1 = csv.getRow(0, 1); // First row
            var row2 = csv.getRow(1, 1); // Second row
            var data = [];

            /**
            * Now make up some sample points using the data
            */
            for (var i=0; i<row1.length; i+=1) {
                data.push( [(row1[i] / 10) * 360, row2[i]]);
            }

            var rscatter = new RGraph.RScatter({
                id: 'cvs',
                data: data,
                options: {
                    labelsAxes: 'n',
                    textAccessible: true
                }
            }).draw();
        });
    };
</script>
