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:
Installation:
* distutils used to install the package. RPMS available.
Plotting:
* 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
document
* 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..
UI:
* 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
Reading data:
* 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
* Images
* 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]
