A Thermometer 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.thermometer.js"></script>

Put this where you want the chart to show up:

<canvas id="cvs" width="100" height="400">
    [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 first row of the CSV file
            var row = csv.getRow(0);

            var thermometer = new RGraph.Thermometer({
                id: 'cvs',
                min: 0,
                max: 50,
                value: row[1],
                options: {
                    valueLabelDecimals: 1,
                    unitsPost: '%',
                    scaleVisible: true,
                    gutterRight: 35,
                    textAccessible: true
                }
            }).draw();
        });
    };
</script>
