The Plotlib Toolkit

Density of N(3,1)

Introduction

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 easily 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. The code should be bug-free, but not very user-friendly yet, since only the low-level APIs are implemented yet. The screenshot above was created with the toolkit.

Download

The current stable version is plotlib-0.4.1-src.tar.bz2 (about 35 KB). You either need the bunzip2-utility to unpack the archive, or a current version of GNU tar. In the latter case, you can use a command like

tar -xvjf plotlib-0.4.1-src.tar.bz2

to untar the archive.

Be sure to download the archive in binary mode. The md5 checksum is:
