Yes, JFreeChart is good. I was prepared to recommend it as a solid 
alternative for a client last year, if they didn't go with a commercial 
alternative. They eventually purchased LogiInfo/LogiStudio products, 
which are seriously more high-powered than JFreeChart. But JFreeChart is 
a good choice.

I have some JFreeChart examples also.

The OP should not underestimate the amount of effort that implementation 
takes with something like JFreeChart, however. Particularly for first or 
second or third projects by people new to the library. Given a chart 
design and a datasource accessible by some technique, the better 
commercial offerings make it possible to knock out a very sophisticated 
user-input driven dynamic chart in less than an hour. Creating a similar 
chart with JFreeChart would take days.

So it's a very good idea to do some early implementations, even as early 
as application requirements gathering, as a proof-of-technology and an 
effort-estimation guide.
