On my system (Ubuntu Dapper, matplotlib 0.87) the fonts DejaVu Sans and FreeSerif show the minus superscript in matplotlib plots, while FreeSans and DejaVu Serif no (they show an empty square).

The \mu character is not in roman font but in italics, while the 'm'
is correctly set to roman. In latex I use the SIunits package to write
the units, so the fonts are correctly in roman even in math
environment. It would be useful something like that in matplotlib too.
However I'll be happy even if I could write greek characters in roman
fonts.
Maybe it's a problem related to the particular font used...
Furthermore font rendering it's a bit odd: the fonts appears to be
bolder than normal Computer Modern fonts used in the latex document.
I've tried to change the font weight (in matplotlibrc) without any
effect. On the contrary mathtext seems to use a font like Times, which
should be bolder, but the overall aspect is lighter.
How can I change the font used by 'mathtext' or 'usetex'? All I want
is use the standard ae fonts I'm using in latex.
Many thanks.

Nice, thanks for the imformation. Do they work in matplotlib 0.87 too? (In my quick test they do not work). Currently I'm not able to change mathtext or "usetex" fonts (except for the font size). The font.serif, font.sans, etc... properties change only the normal text font. Furthermore I have noted that with "usetex" ticks label are rendered differently if they are explicitly set with set_[xy]ticklabels() or not. Compare the ytick labels (automatic) and xtick labels (manually set) in the attached plot. You can see also that the title and x axis label fonts are "boldier" (weightier) than the standard latex Computer Modern fonts (the difference become evident when the image is included in a latex document). This effect is what I was talking about in previous mail. > Best, > Edin Ciao, ~ Antonio PS: Sorry to Edin Salkovic for previous private reply - Take Surveys. Earn Cash.

Re: [Matplotlib-users] matplotlib, math greek letters and latex
Hi Antonino,
If your using the version 0.90 (or SVN) of matplotlib you can also use
mathtext2.
To enable it, put these lines in your matplotlibrc file:
mathtext.mathtext2 : True
mathtext.nonascii : FreeSerif.ttf # Or any unicode font
or, you can set it for your particular script:
rcParams['mathtext.mathtext2'] = True
rcParams['mathtext.nonascii'] = 'FreeSerif.ttf'
You can also set:
mathtext.rm : FreeSerif.ttf # Roman font
mathtext.it : FreeSerifItalic.ttf # Text italic
mathtext.tt : FreeMono.ttf# Typewriter (monospaced)
mathtext.mit: FreeSerifItalic.ttf # Math italic
mathtext.cal: FreeSansOblique.ttf # Caligraphic
Beware that you have to have the freefonts installed on your system,
or in the mpl data-dir.
Best,
Edin

What is the problem with method 3?

Re: [Matplotlib-users] matplotlib, math greek letters and latex
Sorry for the previous mail I've hit Send for error before the mail
was complete.
Here it is the complete mail:
Hi to the list,
I'm using matplotlib to generate graphs during my master thesis. I
want to thank all the developer for providing such flexible tool.
In some plots I have to put greek letters (or sometimes small formulas)
as axis label. I've found three way to accomplish this:
1. Use the unicode string: xlabel(u'Wavelength [μm]')
2. Use mathtext: xlabel(r'$\rm{Wavelength [\mu m]}$')
3. Use usetex: rc(text, usetex=True), xlabel(r'Wavelength [$\rm{\mu m}$]')
I have some problem with each method, any hint is appreciated.
1. This method works ok as far as I choose a unicode font with the
greek letters, for example:
rcParams['font.serif'] = 'DejaVu Serif'
However with unicode strings I'm not able to do exponent and deponent
text (i.e cm^-1)
Methods 1. and 2. are more flexible, however I'm no able to to put the
\mu character in roman fonts. I don't know if this is the intended
behavior or if it's a bug...
Furthermore, is there a simple way to set fontsize for all text
elements (labels, title, ticklabels). Currently I'm doing:
rcParams['font.size'] = 12
rcParams['xtick.labelsize'] = 14
rcParams['axes.titlesize'] = 16
rcParams['axes.labelsize'] = 14
The relative setting (large, small,...) seems to refer always to the
default font size (set in matplotlibrc). Is there a way to set the
font.size property and then update all the other relative values to
reflect the change?
Many thanks for any help.
