Filipe: I believe I've fixed it - your shapefile now displays correctly

Just a thought to throw out there... maybe the call
signatures/functionalities of boxplot() and errorbar() should get merged?
To me, I imagine these kinds of plots as being two sides of the same coin.

Using anything but the CM and STIX fonts in mathtext ultimately leads to 
a world of pain and I consider it "unsupported", because there are 
custom tweaks to get the alignment working that end up being missing.
However, if you really want to try it you can set the following rcParams:
 mathtext.default: regular # Use the same font for math as regular text
 mathtext.fontset: custom # Don't pull any glyphs from cm or stix
Then you can write your string entirely in math syntax, eg.:
 r"$VCD_{strat} O_3 [DU]$"

Cool, this seems to work :)
Now, I only have one issue:
If I set a text, for example via
 ylabel(r"VCD$_{\sf strat}$ O$_{\sf 3}$ [DU]")
the subscript "strat" actually gets typeset in my OTF font, but the subset
"3" gets typeset in the standard math font (the fonts Cmr10 and Cmss10 get
embedded in the PDF file). This doesn't look nice, because I am using
MyriadPro, which is a sans-serif, while the CMR/CMSS fonts are serif fonts
...
Any ideas how to solve this?
Cheers!
Andreas.

Yes. Put the font somewhere in your font search path. (Where that 
would be depends on your platform, but for user-local fonts, use 
"~/.fonts" on Linux, "~/Library/Fonts" on OS-X, I don't recall on 
Windows, but Googling should give you something). You will need to 
delete the matplotlib font cache so that it will discover new fonts. 
This lives in "~/.matplotlib/fontList.cache" on Unix platforms. Then 
you can change the default font family by setting the "font.family" 
rcParam to the name of the font.
Note that matplotlib does not support all of the features of otf fonts, 
like glyph substitution etc. -- it really only uses the basic 
"TrueType-like" parts of the font file.

This is another avenue, and has the potential to use the advanced 
features of otf. I've never attempted this myself, but perhaps one of 
the other users on this list who uses usetex more often can comment.

Hi,
I would like to use .otf fonts for typesetting text (axes, titles, labels,
legends, ...) in matplotlib. Is this possible? If yes, how?
If not directly, perhaps via XeTeX?
Cheers,
Andreas.

This would only happen if the program explicitly calls for macosx backend
with the use() function, or you have macosx backend selected in your
.matplotlibrc file.

Hi All,
I am using a Ubuntu 10.04 machine (Linux 2.6.32-28-generic #55-Ubuntu SMP
Mon Jan 10 21:21:01 UTC 2011 i686 GNU/Linux)
And I am running Matplotlib version 0.99.1.1.
I got following errors when I am trying to run a program:
Traceback (most recent call last):
 File "PS3_audionoise.py", line 11, in <module>
 import matplotlib.pyplot as p
 File "/usr/lib/pymodules/python2.6/matplotlib/pyplot.py", line 78, in
<module>
 new_figure_manager, draw_if_interactive, show = pylab_setup()
 File "/usr/lib/pymodules/python2.6/matplotlib/backends/__init__.py", line
25, in pylab_setup
 globals(),locals(),[backend_name])
 File "/usr/lib/pymodules/python2.6/matplotlib/backends/backend_macosx.py",
line 20, in <module>
 from matplotlib.backends import _macosx
ImportError: cannot import name _macosx
Seems the _macosx is for Mac, not Ubuntu.
I tried to install matplotlib both from source and using apt-get. But this
error happens every time. Does any one know how to fix this?
Thanks!
