Ptplot is a simple, easy to call graph plotting in Java from the Eletrical Engineering and Computer Science of University of California at Berkley. It has been installed on the School Linux system and is a sensible replacement for SimpleGraph first introduced in Sceintific Programming.
ptplot is a very flexible two-dimensional graphic plotting package with sensible defaults making it very easy to call from within Java programs. It allows considerable control over axis, ranges and support error bars. It also allow the graphs to be saved, either in XML format or, more importantly, exported to eps for easy inclusion in other documents.
