PyX' home has been moved to The source code repository has been converted to git and is now hosted at
2015-11-02: PyX 0.14.1 released

Here it can be modified and output not just to SVG, but also to the other output formats. Various improvements and bug fixes complete this release.
2013-12-20: PyX 0.13 released

2007-10-03: PyX 0.10 released
This release adds 3d plotting facilities to PyX using parallel or central projection. Two new graph styles grids and surfaces can be used in 3d graphs as well as some existing generic graph styles (symbols, lines, errorbars etc.). Several new examples, various other improvements requested by PyX users and some bugfixes complete this release.
2006-09-14: Talk about Type1 fonts and PyX in Rosenheim
A talk about Type1 fonts and PyX was presented at the fall meeting of the German Speaking TeX User Group DANTE e.V. (September 14th and 15th, Rosenheim). The presentation is available in German (pdf, 19 pages, 226 KB) and in a crude english translation.
2006-09-11: First public version of PyXPlot released
Dominic Ford released the first public version of PyXPlot, which provides a Gnuplot-style interface to PyX. PyXPlot already supports a large subset of Gnuplot's original functionality, always combined with the high-quality output of PyX.
2006-05-24: PyX 0.9 released
This release features a new set of deformers for path manipulations like smoothing, shifting, etc. A new set of extensively documented examples describing various aspects of PyX in a cookbook-like fashion have been written. Type 1 font-stripping is now handled by a newly written Python module. The evaluation of functions for graph plotting is now left to Python. Thereby some obscure data manipulation could be removed from the bar style for handling of nested bar graphs. Transparency is now supported for PDF output. Many more small improvements and bug fixes top off this release.
2006-01-20: New PyX tutorial for Gnuplot users
Titus Winters wrote a very nice tutorial explaining the basics of PyX's graph-plotting facilities for users familiar with Gnuplot.
2005-08-13: PyX 0.8.1 released
This release fixes some bugs in the path module and the output of decorated paths. The fallback for kpathsea was considerably improved in speed (it was unintensionally slowed down in 0.8). The inclusion of the bounding box information in PS and PDF files is now optional. It is suppressed by default when a paperformat is specified. A new path example completes the release.
2005-07-13: PyX 0.8 released
PyX now supports PDF output and also the generation of multi-page PS/PDF documents. The internals of the path system have been cleaned up and the external interface has been streamlined.
