JFreeChart is reasonably priced (free, subject to the GNU LGPL): http://www.object-refinery.com/jfreechart/index.html There are plenty of demos in the JFreeChart download to get you started, plus a free installation guide (explains how to run the demos etc). If you want to learn more, we sell a developer guide for JFreeChart as a way of funding the project. Regards, Dave Gilbert JFreeChart Project Leader
Just in case you think David's just plugging his pet project, I'd like to endorse JFreeChart as well. I had a good look round for a Java charting library a little while ago and JFreeChart was way better than anything else I could find for free or a reasonable (or in some cases not so reasonable) price.

See RChart: http://www.java4less.com and click on "RChart". It has the following advantages: - very reasonable price (starting at $24) - Works as applet, servlet or bean. - It works with java 1.1 also. - Supports more than 18 types of charts and has interactive features (zoom,tips,scroll,html links) - Includes RChart Visual Builder (almost no programming) - Can read data from database. - source code is available can be freely modified for commercial applications also.
I’ve looked at a lot of different solutions, and in my humble opinion Aspose is the way to go. Here’s the link: http://aspose.com
