Veusz is a scientific plotting package written in Python (currently
100% 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 0.4:
* distutils used to install the package. RPMS available.
* Different error bar styles (diamond, curve...)
* "Matched" axes, with the same scale on each
* Data can be linked from external files instead of embedded in
* Filled regions under/over functions or xy plots
* Improved function clipping near edge of plot
* Default values can be set for settings, which are remembered
between sessions (e.g. blue points for xy3).
* Rotated text labels
* Improved fitting, giving results from chi2, etc..
* Can move around widgets and delete them
* Exception dump dialog to send bug reports
* Improved import dialog help
* Propagate settings between widgets
* Window positions are saved between sessions
* Better error handling when reading data
+ Numerous bug fixes
Features of package:
* X-Y plots (with errorbars)
* 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
To be done:
* Contour plots
* UI improvements
* Import filters (for qdp and other plotting packages, fits, csv)
* Data manipulation
* Python embedding interface (for embedding Veusz in other programs).
[some of the external interface is complete]
Python (probably 2.3 or greater required)
Qt (free edition)
PyQt (SIP is required to be installed first)
Microsoft Core Fonts (recommended)

manual is in pdf, html and text format (generated from docbook).
If you enjoy using Veusz, I would love to hear from you. Please join
the mailing lists at
to discuss new features or if you'd like to contribute code. The
newest code can always be found in CVS.
