Veusz
Veusz is a GUI scientific plotting and graphing package. It is designed to produce publication-ready
Postscript or PDF output. SVG, EMF and bitmap export formats are also supported. The program runs
under Unix/Linux, Windows or Mac OS X, and binaries are provided. Data can be read from text, CSV,
HDF5 or FITS files. Additionally you can also enter, manipulate or examine data from within the
application.
In Veusz plots are created by building up plotting widgets with a consistent object-based interface.
The program also provides a command line and scripting interface (based on Python) to its plotting
facilities. It can also act as a Python plotting module.
Veusz is written in Python. Its user interface uses PyQt and Numpy is used to manipulate data
.
