# 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: 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.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>
