Veusz

Veusz is an interactive graphical scientific plotting and

graphing package. It is designed to produce publication-ready

PDF output. SVG, EMF and bitmap export formats are also

supported. Data can be read from text, CSV, HDF5 or FITS

files. In addition, you can also enter, manipulate or examine

data from within the application. 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.

In Veusz plots are created by building up plotting widgets with

a consistent object-based interface. Plotting types support by

Veusz include the following: x-y, function, contour, image,

stepped, date, vector field, box, polar, ternary, nested and

stacked. Plots can also include multiple axes.
