This demo fetchs the first row of the CSV file (not including the labels) but only uses the first value (as the VProgress value)
This goes in the documents header:<script src="RGraph.common.core.js"></script> <script src="RGraph.common.csv.js"></script> <script src="RGraph.vprogress.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)
{
// Fetch the the first row
var row = csv.getRow(0, 1);
var vprogress = new RGraph.VProgress({
id: 'cvs',
min: 0,
max: 10,
value: row[0],
options: {
margin: 10,
textAccessible: true
}
}).draw();
});
};
</script>
