Yes, the inputenc package from latex lets you use unicode.
Try adding this to your script:
plt.rc('text.latex', preamble='\usepackage[utf]{inputenc}')
Note that this setting is not officially supported, whatever
that means :)
I think it means that Darren, who did most of the heavy lifting for
these features, was getting tired of the endless line of additional
things TeX users wanted to do and the difficulties supporting these
across all platforms (eg MikTex on Windows) and drew a line in the
sand saying I'll add this stuff but if you report problems I may not
stay up all night trying to fix them.
That is a fair explanation. Adding arbitrary lines to the latex
preamble adds an incredible amount of flexibility if you are a user,
and it provides plenty of rope with which to hang yourself if you are
a developer (answering questions/problems related to people writing
bad python code, misconfigured latex installations, and bad latex
code!). At the time, we had finally shaped the latex backend into
something that worked across platforms (and different versions of
latex installations), plus I was also finishing up grad school and
starting a new job, so I had reservations about even adding this
feature to the library. But people really wanted it so we compromised.

Yes, all strings are processed by LaTeX.

In theory, \\n \\n %b or r\n \n %b, however only the former

There's another problem: \n is not a valid LaTeX command.

Try adding this to your script:

I also like the txfonts package:
\usepackage[varg]{txfonts}
which changes the default font to Times, including the text in
mathematical expressions. It looks great.

Can you (or someone else) confirm this? I don't think pts is a
proper tex unit and it should be \vspace{10pt}. Maybe this is a typo
in the email. I'm asking this because it does not work for me, and I
don't think it is supposed to work (but I may be wrong).

Good tip. I also like \usapackage{fourier} to get the utopia fonts, which are
particularly useful since I'm always plotting concentrations and having a
upright mu ($\othermu$) is really nice.

Re: [Matplotlib-users] DateFormatter + Latex issue
If what you want is to have more padding for the major tick labels, I
recommend you to use
rcParams['xtick.major.pad'] = 20
If you don't like to change the global setting, you may set the
ticklabel padding for an specific axis. Try
for tck in ax.xaxis.get_major_ticks():
tck.set_pad(20)
tck.label1 = tck._get_text1()

You're right!
\vspace{10pts} adds space (seems about 10 points) but it also
prints a s before the space, which I didn't see before.
Now, \vspace{10pt} doesn't work for me... it simply does nothing.
Bye.

As I said, it is not supposed to work, because of some technical reason. When there is a single line of text, it is hardly possible to get to know the original baseline of the text. By the way, the original problem that \n\n %b didn't work seems like a actual bug (it is supposed to work without escaping '\n'). This should now be fixed in the svn (r8135 in maint. branch and r8136 in HEAD) . Still, it is recommended to adjust the pad of the ticklabels instead of fiddling with newlines and etc. Regards, -JJ -- SOLARIS 10 is the OS for Data Centers - provides features such as DTrace, Predictive Self Healing and Award Winning ZFS.

I think it means that Darren, who did most of the heavy lifting for
these features, was getting tired of the endless line of additional
things TeX users wanted to do and the difficulties supporting these
across all platforms (eg MikTex on Windows) and drew a line in the
sand saying I'll add this stuff but if you report problems I may not

[Matplotlib-users] DateFormatter + Latex issue
Hello list,
If I use DateFormatter with latex and lines breaks like this
DateFormatter(\n \n %b) I get an latex error:
http://pastebin.com/m5b186ded
Although, if I do not use the line breaks,
DateFormatter(%b)
The problem disappears.
Below is a script that reproduces what I'm talking about:
#Example:
from pylabimport *
from matplotlib import rcParams
rcParams['text.usetex'] = True
fig = figure()
ax = fig.add_subplot(111)
fig.subplots_adjust(bottom=0.2)
t = arange(100,110,.1)
u = sin(t)
v = cos(t)
quiver([t],[[0]*len(t)],u,v)
major = DayLocator([10,04])
minor = DayLocator()
majorF = DateFormatter(\n \n %b) # problem
#majorF = DateFormatter(%b) # no problem
minorF = DateFormatter('%d')
ax.xaxis.set_major_locator(major)
ax.xaxis.set_minor_locator(minor)
ax.xaxis.set_major_formatter(majorF)
ax.xaxis.set_minor_formatter(minorF)
gca().xaxis_date()
title(r$\alpha \beta \gamma \delta$)
show()
I'm using the latest svn version with qt4 as backend.
Thanks, Filipe
