Veusz

Veusz is a scientific plotting package, designed to create publication-ready Postscript or PDF output. It features an easy to use graphical interface as well as a command line interface and can be scripted or embedded in Python scripts. Graphs are constructed in a modular fashion from separate components. Datasets can be interactively modified or created from within the program.

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.
