From http://matplotlib.sourceforge.net/fonts.html : Postscript Postscript, despite its age, is still a great output format. Most publishers accept it, it scales to arbitrary resolutions, you can import it directly into LaTeX document, and send it directly to postscript printers. The only requirement to generate postscript output is the Numeric module and some AFM fonts on your system. Even the latter is only a quasi-requirement, because matplotlib ships with some of the most popular font files. These are Adobe Font Metric files, which have the '*.afm' extension. matplotlib comes with it's own AFM parser to read these files and select the best match for the font you've chosen. If you want additional fonts, set the AFMPATH environment variable to point to the dir containing your AFM font files. matplotlib willl recursively search any directory in AFMPATH, so you only need to specify a base directory if multiple subdirectories contaning '*.afm' files.

Not really. Gnuplot's output is LaTeX with a couple of native
Postscript directives inbetween. It's inluded into my document with
\input plot.plt rather than \includegraphics{plot.eps}.
I mentioned the advantages of this approach in the footnote:

Probably not raw enough, but I don't know how basic matplotlib wants it to be. You could switch the axes off and draw everything as lines using plot coordinates, but I don't know how sensible this would be. On the other hand, the pslatex output of Gnuplot is one of the very few things that hold me there. If matplotlib produced something equivalent, (at least) I wouldn't call for a Gnuplot backend anymore.

What do you mean with this? Do you want to mimic TeX's quality as a typesetter, or do you think the goal should be output in real LaTeX format (like pslatex does)? Both! There is a need for mathematical typesetting in matplotlib without a dependency on TeX. Not everyone is making plots destined for inclusion in their LaTeX-typeset papers. However, some people, like you and me, *are* making such plots and a pslatex-based solution would be a perfect fit for that use case. -- Robert Kern [EMAIL PROTECTED] In the fields of hell where the grass grows high Are the graves of dreams allowed to die. -- Richard Harter -- http://mail.python.org/mailman/listinfo/python-list

The latter would be more useful in my opinion, and much easier, too. Easier... psfrag tricks can be done right now, while full latex output requires writing a new matplotlib backend. It would certainly be a _great_ project, but not one I'm about to undertake, while it's reasonable for me to use psfrag to fix a few labels here and there to use proper latex. So while I agree with you that in the long run a latex backend would be ideal, as a stop-gap solution I can live with psfrag.
