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 or FITS files, and data can be manipulated or examined 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.

X-Y plots (with errorbars)

Images (with colour mappings)

Contour plots (filled/unfilled)

Stepped plots (for histograms)
