PyX is a Python package for the creation of encapsulated PostScript figures. It provides both an abstraction of PostScript and a TeX/LaTeX interface. Complex tasks like 2d and 3d plots in publication-ready quality are built out of these primitives.PyX seems to be under active development and boasts a direct interface to LaTeX. The samples look impressive. A quick perusal of the documentation makes it seem that PyX has all the primitives needed to create a reasonable version of the Standard Celeration Chart. I'm so frustrated with R and Rpy right now that I would love to drop everything and rewrite the rendering system for the metacharting project. Unfortunately, I've got to finish my dissertation proposal before I take on anything new. In spite of the recent difficulties I've had getting Rpy to install under Mac OS X, I do have it working on both my linux server and my G5 tower. The current arrangement works well enough for the time being.
