<h1>A VProgress chart using the CSV reader</h1>
<div style="background-color: #ffc; border: 2px solid #cc0; border-radius: 5px; padding: 5px;">
<b>Note:</b>
For browser security reasons the AJAX demos don't work offline. You can view the demos on the RGraph website here:
<a href="http://www.rgraph.net/demos/" target="_blank" rel="nofollow">http://www.rgraph.net/demos</a>
</div>
<p>
This demo fetchs the first row of the CSV file (not including the labels) but only uses the first value (as the VProgress value)
</p>
<canvas id="cvs" width="100" height="400">[No canvas support]</canvas>
<script>
window.onload = function ()
{
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>
<p></p>
This goes in the documents header:
<pre class="code">
<script src="RGraph.common.core.js"></script>
<script src="RGraph.common.csv.js"></script>
<script src="RGraph.vprogress.js"></script>
</pre>
Put this where you want the chart to show up:
<pre class="code">
<canvas id="cvs" width="100" height="400">
[No canvas support]
</canvas>
</pre>
This is the code that generates the chart:
<pre class="code">
<script>
window.onload = function ()
{
RGraph.CSV('/sample.csv', function (csv)
{
<span>// Fetch the the first row</span>
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>
</pre>
