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.bar.js"></script>
</pre>
Put this where you want the chart to show up:
<pre class="code">
<canvas id="cvs" width="600" height="250">
[No canvas support]
</canvas>
</pre>
This is the code that generates the chart:
<pre class="code">
<script>
window.onload = function ()
{
RGraph.CSV('id:klkl', function (csv)
<span>//RGraph.CSV('/sample.csv', function (csv)</span>
{
<span>/**
* Fetch the first row of the CSV file, starting at the second column
*/</span>
var data = csv.getRow(0, 1);
<span>/**
* Fetch the first column which become the labels
*/</span>
var labels = csv.getCol(0)
labels.push('Fred')
var bar = new RGraph.Bar({
id: 'cvs',
data: data,
options: {
labels: labels,
labelsAboveSpecific: ['Monday','Tuesday','Wednesday','Thursday','Friday','Saturday','Sunday'],
labelsAboveSize: 8,
noxaxis: true,
shadowOffsetx: 2,
shadowOffsety: 2,
shadowBlur: 5,
hmargin: 15,
backgroundGridAutofitNumvlines: 7,
colors: ['Gradient(#DDF:#01B4FF)'],
