Veusz is a scientific plotting package written in Python. It uses PyQt for display and user-interfaces, and numarray for handling the numeric data. Veusz is designed to produce publication-ready Postscript output.

Veusz provides a GUI, command line and scripting interface (based on Python) to its plotting facilities. The plots are built using an object-based system to provide a consistent interface.

Changes from 0.8:
Please refer to ChangeLog for all the changes. Highlights include:

Contour support (thanks to the code of the matplotlib guys!)
Undo/redo
Rubber band axis zooming

Features of package:

X-Y plots (with errorbars)
Contour plots
Images (with colour mappings)
Stepped plots (for histograms)
Line plots
Function plots
Fitting functions to data
Stacked plots and arrays of plots
Plot keys
Plot labels
LaTeX-like formatting for text
EPS output
Simple data importing
Scripting interface
Save/Load plots
Dataset manipulation
Embed Veusz within other programs

To be done:

If you enjoy using Veusz, I would love to hear from you. Please join the mailing lists at

https://gna.org/mail/?group=veusz

to discuss new features or if you'd like to contribute code. The newest code can always be found in CVS.

If non GPL projects are interested in using Veusz code, please contact me. I am happy to consider relicencing code for other free projects, if I am legally allowed to do so.

Cheers

Jeremy
