..only i wonder if you can deploy your application which incorporates either of the above in aproduction server.Arnt there any licensing/purchasing issues ??..also would like to know if any of our fellow ranchers came accross any issues related to performance of these charts and graphs..
To repeat what others have said, requires education, to challenge it , requires brains.

Both JChart2D and JFreeChart are licensed under the LGPL, so I'm not sure what license/purchase issues you have in mind.
If performance is a problem depends on the concurrency that you encounter in your web app. Image generation does take a bit of CPU time, so if 100 users request charts simultaneously, there will probably be a delay. [ October 16, 2007: Message edited by: Ulf Dittmer ]
