I was working on a figure, using mathtext and the Arev Sans fontset,
and I noticed that \Delta does not display correctly. In fact, none
of the capitol greek letters show up. It claims they are missing
(and I do not default back to CM). However, I _know_ Arev Sans has
\Delta (and the others).
Little \delta and all the other little greek letters are there:
>>> text(0.5, 0.5, r'$\Delta$')
/Library/Frameworks/Python.framework/Versions/2.5/lib/python2.5/site-
packages/matplotlib/mathtext.py:808: MathTextWarning: Font
'BitstreamVeraSerif-Roman' does not have a glyph for '\Delta'
MathTextWarning)
/Library/Frameworks/Python.framework/Versions/2.5/lib/python2.5/site-
packages/matplotlib/mathtext.py:817: MathTextWarning: Substituting
with a dummy symbol.
warn("Substituting with a dummy symbol.", MathTextWarning)
<matplotlib.text.Text instance at 0x476f8f30>
>>> text(0.5, 0.5, r'$\alpha \beta \gamma \delta \nu \eta \zeta \pi
\xi$')
<matplotlib.text.Text instance at 0x478a6e18>
Am I doing something wrong?

The log shows that for some reason it is pulling in
BitstreamVeraSerif-Roman instead of Arev Sans for that character. It
could be that it isn't finding the Arev fonts on your system.
Can you send your matplotlibrc file? (Particularly the mathtext.*
options...) Also, can you set "verbose.level" to "debug-annoying" and
send us the output?
Cheers,
Mike

It seems to me that Arev is being used from the debug information.
See the log below.

The line I'm referring to is this --->
/Library/Frameworks/Python.framework/Versions/2.5/lib/python2.5/site-packages/matplotlib/mathtext.py:808:
MathTextWarning: Font 'BitstreamVeraSerif-Roman' does not have a glyph
for '\Delta'
MathTextWarning)
Can you send your matplotlibrc settings and the mathtext expression you
are using? One or the other of those is causing Vera Serif to be used
for the \Delta character rather than Arev Sans.
Cheers,
Mike

I see what's going on here. Upper-case Greek letters are always upright (non-italic) in mathtext. TeX does this, and it is apparently a long standing American typographic convention. So, when it goes to print the "\Delta", it looks at "mathtext.rm", which in your case you have set to "serif", which causes it to look at the setting for "font.serif", in which the first font it finds is "Bitstream Vera Serif", which doesn't have Greek characters. Personally, I like to set the math fonts explicitly, rather than using the font categories. This is what I set for using Arev Sans: mathtext.cal : Arev Sans:oblique mathtext.it : Arev Sans:oblique mathtext.rm : Arev Sans mathtext.bf : Arev Sans:bold mathtext.sf : Arev Sans I may consider adding "arev" and "arevsans" values to "mathtext.fontset" that would do nothing more than set the "mathtext.*" values to reasonable defaults to avoid this confusion. (Which would of course require that the Arev fonts are available -- they aren't included with matplotlib). I still think it's useful and reasonable to provide access to full font customization, but it would be nice to support the common case in a more direct way. Hope that helps.

This makes sense now. I used to have my fonts set up this way, but then changed them based on one of the newer matplotlibrc.default files. Now I changed it back, and things work fine. -Rob ---- Rob Hetland, Associate Professor Dept. of Oceanography, Texas A&M University http://pong.tamu.edu/~rob phone: 979-458-0096, fax: 979-845-6331 |
