Veusz is Copyright (C) 2003-2008 Jeremy Sanders <jeremy at jeremysanders.net>
Licenced under the GPL (version 2 or greater).
Veusz is a scientific plotting package written in Python, using PyQt4
for display and user-interfaces, and numpy for handling the numeric
data. Veusz is designed to produce publication-ready Postscript/PDF
output. The user interface aims to be simple, consistent and powerful.
Veusz provides a GUI, command line, embedding and scripting interface
(based on Python) to its plotting facilities. It also allows for
manipulation and editing of datasets.
Feature changes from 1.0:
* Axes autoscale when plotting functions
* Labels can be dragged around on plots
* More marker symbols
* SVG export of plots
* The point plotting and axis range code has been rewritten.
* Includes quite a few minor bugfixes
Features of package:
* X-Y plots (with errorbars)
* Line and function plots
* Contour plots
* Images (with colour mappings and colorbars)
* Stepped plots (for histograms)
* Fitting functions to data
* Stacked plots and arrays of plots
* Plot keys
* Plot labels
* LaTeX-like formatting for text
* EPS/PDF/PNG export
* Scripting interface
* Dataset creation/manipulation
* Embed Veusz within other programs
* Text, CSV and FITS importing
Requirements:
Python (2.3 or greater required)
http://www.python.org/
Qt >= 4.3 (free edition)
http://www.trolltech.com/products/qt/
PyQt >= 4.3 (SIP is required to be installed first)
http://www.riverbankcomputing.co.uk/pyqt/
http://www.riverbankcomputing.co.uk/sip/
numpy >= 1.0
http://numpy.scipy.org/
Microsoft Core Fonts (recommended for nice output)
http://corefonts.sourceforge.net/
PyFITS >= 1.1 (optional for FITS import)

For documentation on using Veusz, see the "Documents" directory. The
manual is in pdf, html and text format (generated from docbook).
Issues:
* Can be very slow to plot large datasets if antialiasing is enabled.
Right click on graph and disable antialias to speed up output.
* The embedding interface appears to crash on exiting.
If you enjoy using Veusz, I would love to hear from you. Please join
