Hi Guys : I've noticed that JFreeChart is not "really" open source, i.e., the documentation is deliberately vague ; and there is a "paid" documentation package you can buy. I wanted a simple, easy to use charting library for java, that (preferrably) was small enough to embed (with source), or had a maven repository....
Any suggestions ?
Im finding at this point that would be easier to use swing graphics 2D to code charting widgets from scratch, then trying to reverse engineer JFreeChart's documentation in my mind.
JGraph is nice, but its only for more theoretical, computer sciencey types of graphs... It doesnt appear to support basic numerical charting tasks.
XChart is a light-weight Java library for plotting data that would be a potential alternative to JFreeChart. Its focus is on simplicity and doesn't have every capability that JFreeChart has, but it offers a rich set of charting features. The jar is only ~86 KB as of the 2.0.0 release, and it has no dependencies. It's licensed under Apache 2.0 and is hosted on Github. Disclaimer: I'm the lead devloper of the project.
