Hi all,
When I use;
text(0.6, 0.6, r'$\mathcal{A}\mathrm{sin}(2 \omega t)$', fontsize=20)

Hi there,
When I use;

It looks as if you're using 0.90.1. All of these issues are fixed in
0.91.2. If you can upgrade, that's probably your best bet.
Or, if you have all the requirements, you can set "text.usetex" to True
in your matplotlibrc which will use the "real" TeX on your system to
typeset math -- that sho
Like your last question, I think you're using the current release's
documentation (0.91.2) with an old release (probably 0.90.1 or earlier).
pyplot did not exist in 0.90.1, but I believe everything that is now in
pyplot used to be in pylab, so you could just import that instead.

Jeff - I think the way GMT does it would be okay - they have a
latitude of true scale, which I usually choose as the center latitude
of the map.
I was thinking we should allow people to choose the "simple" or
"fancy" options. Do you think it will be okay to have the height of
the bar and
I'm trying to use the pylab interface of matplotlib interactively. I'd
like to enter some commands interactively to generate some data, plot a
graph based on the data, inspect the graph, enter more interactive
python, plot another graph, and so on. Instead, what happens is either

I need QImage in order to display or use in GUI , for exa. in QFrame or
QLabel , I can convert the Image to QImage , but the problem is that I
haven't access to Image object without saving that , also I can convert the
figure (Plot) to string or buffer but I don't know what should I do after
that
