# 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: 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.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>
