PyX — Python graphics package

3d plot example
3d plot example


PyX is a Python package for the creation of PostScript and PDF files. It combines an abstraction of the PostScript drawing model with a TeX/LaTeX interface. Complex tasks like 2d and 3d plots in publication-ready quality are built out of these primitives.


  • PostScript and PDF output for device independent, freely scalable figures
  • seamless TeX/LaTeX integration
  • full access to PostScript features like paths, linestyles, fill patterns, transformations, clipping, bitmap inclusion, etc.
  • advanced geometric operations on paths like intersections, transformations, splitting, smoothing, etc.
  • sophisticated graph generation: modular design, pluggable axes, axes partitioning based on rational number arithmetics, flexible graph styles, etc.

Status and Availability

PyX is in steady development. Planned features are listed on the roadmap. The current release, PyX 0.13, is available at the download section of the SourceForge project page.


2013-12-20: PyX 0.13 released
PyX has been ported to Python 3. It now requires Python 3.2 and above. Python 2 users should continue to use the previous PyX releases. Along with the port the text module was modernized and got a new documentation. In addition, the normpath now removes cusps from normcurves by spliting the curves on instability points such that tangents etc. are always well-defined. Various improvements and bug fixes complete this release.
2012-10-26: PyX 0.12.1 released
This release fixes drawing bugs in the gradient style for the recently introduced key graph.
