A Bar chart using AJAX
Summary: RGraph has AJAX functionality that makes integration with your existing scripts easy and painless.
Here is an example of a 3D variation of the Bar chart which is both animated using the
grow() effect and which is also fetching its data via AJAX.

If you view the AJAX script you'll see that it just outputs the numbers and nothing else - so no labels or title. So on the chart the labels are just hard coded.
The rest of the configuration is pretty straight-forward - and you can see it below.
