Veusz

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 (plots can additionally saved to SVG or printed to PDF).

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.

What is new in version 1.22:

Changes in 1.22:
- Add option to ignore white space following delimiters when importing CSVs
- Allow x/yedge and x/ycent to be inverted to change data order when import 2D data
