PyX — Python graphics package

3d plot example
3d plot example


PyX is a Python package for the creation of PostScript, PDF, and SVG 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, PDF, and SVG 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 0.16, is available at the PyPI project page.


2022-10-16: PyX 0.16 released
This release enables a shortcut for accessing graph-component attributes, simplifying the modification of default components. Small improvements and several bug fixes, especially for the text alignment with TeX Live 2020, are included.
2019-07-14: PyX 0.15 released
This release introduces a new text engine UnicodeEngine, which enables simple typesetting with Type1 fonts without using TeX/LaTeX. The graph axis texters have been adjusted to work on the UnicodeEngine, as well. The exponential and mixed graph axis texters have been merged into the new default texter.
PyX' home has been moved to The source code repository has been converted to git and is now hosted at
