Re: [Matplotlib-users] problem with usetex \color
Hi Jae-Joon,
thank you very much for taking the time and for your suggestions. Indeed the
different distillers yield different output as you can see in the attached
pics. Does this mean that this behaviour is due to tex / the installed
distiller or are different distillers differently handled in matplotlib?
Especially the different used papersize A4/Letter vs. small region around text
seems to be remarkable.
best regards
Matthias

ps backend undergoes several steps (tex - dvi - ps - [distiller]) to
produce the final output, and it is hard to track down the problem
without actually reproducing one.
Just in case, can you change your distiller option and see if it makes
any difference?
rc(ps, usedistiller=ghostscript) # this would be the default
or
rc(ps, usedistiller=xpdf)

Unfortunately, I don't see such problem, although the problem seems to
be due to a wrong bounding box.
Are you using the most recent svn? There has been some recent changes
in ps backend. Before the changes (r7068, r7074), the ps backend tried
to adjust the bounding box of the output ps file. However, as far as I
can see, this often gave a wrong bounding box (and I guess your
problem might be related with this issue). The above mentioned changes
somehow bypass that bbox adjustment. The resulting bounding box should
have the size of the figure if saved in eps, or size of the paper
(letter or a4, I guess) if saved in ps.

guess this may have been a design decision.
As far as I can see, MPL currently does not support texts with

Obviously, this doesn't work any more as soon as you reach 20...

In addition to that, I have the strange behaviour that the b is not
displayed at all when using
f.text(0.5, 0.5, r{\color[rgb]{0,1,0} a } b)
-- gives only a green a
but it is without the color command:

Pretty weird, isn't it?

Even if your font is not monospaced, it might have tabular figures:

I think at least Computer Modern Roman (the default font in TeX) does
