Hello,

I'd like to know what are the possibilities so far to display charts with RAP.

I found no chart widget in qooxdoo:
http://demo.qooxdoo.org/current/demobrowser/

The solution I found is using BIRT, which is nice:

Any other possibility?

How difficult would it be to use JFreechart within RAP for instance ?

Hi Frederic,
using jfreechart is rather easy. JFreeChart can render charts into image
files. Do this on the server and use the image as Background for a Label
or a Composite. There is your chart :)

Further on, you can register a mouseListener on the Label and catch
click events. With the x and y coordinates of the event you can get the
underlying ChartEntity (bar, point, etc.) from JFreeChart.

Regards,
Björn

I would also like to recommend looking at:

David Donahue's wonderful Google Visualization contribution:

Also forthcoming next week (hopefully) I will post an implementation of some charting capabilities for Emprise Javascript Charts within RAP: http://www.ejschart.com/

However, you would have to buy a license for the actual Emprise code to use it for commercial purposes.
