A Scatter 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.scatter.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>
    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) {
            data.push([row1[i], row2[i]]);
        }


        new RGraph.Scatter({
            id: 'cvs',
            data: data,
            options: {
                xmax: 10,
                xscale: true
            }
        }).draw();
    });
</script>
