The Plotlib Toolkit is a library of classes designed for plotting and printing mathematical functions and statistical data using the Java2D-APIs of Java 2.

Although some solutions exist to the problem of plotting data (mainly for presentation on webpages using applets), there is to my knowledge no GPLed solution which solves more than very specific parts of the problem. This toolkit was therefore designed from scratch with the following goals in mind:

sound object-oriented design, making extensions to the toolkit easyly possible
usage of the extended Java2D-API
batch processing using XML as a description language for plots
support for presentation as well as printing
high-level classes for simplified use of the toolkit in standard situations

This project is in alpha state. The layout of the packages has been done (although this too is subject to change) and some of the primitives are implemented.
