Dear All,
I am quite a newbie about Python and Pylab, but I am starting to like
the ease you can develop with using these tools.
I am interested in 2D radial plots (think for instance about the plot
of the temperature along the cross-section of a pipe).
I had a look at the tutorial online, in

Hello,
Thanks for your suggestion, but I still have a problem.
Maybe I did not make myself clear (or most likely I have a problem
about how to implement your suggestion): actually I have T=T(r,theta)
and I would like to make a 2D plot using colors
Dear All,
I am a bit puzzled at an unusual problem I am experiencing.
Fundamentally, I call a couple of functions and I plot some data.
First, I create a semilog plot using pylab.semilogx, then I make a
normal linear plot.
But, in the second case I get an error message:

Dear All,
Some weeks ago I emailed the list asking how to represent data on a
non-rectangular domain (namely a velocity component along a tube
cross-section in my case).
I now can tell that everything goes as in the example described by
Hansen in Matplotlib-users Digest, Vol 14, Issue 13, which

I am sending this email out of frustration, but I hope that someone will
be able to tell me what is going on.
I am using pylab on a Debian testing box.
I have the feeling that there is some problem with pylab when I
alternate, as I am doing now, many linear and log-log plots. Very

Dear All,
I am running Debian testing on my box and I installed matplotlib from
the standard repositories.
From time to time I experience a problem when plotting several figures.
Consider the following code snippet:

Dear All,
I think the solution to my problem must be a one-liner, but I have
been unsuccessful.
I am trying to use latex formulas (nothing dramatically complicated)
inside a figure.
I suppose everything is working correctly on my system.
I tried running the example at:

Unfortunately, it seems that there is something broken either with
pylab or Python (I have been upgrading the system these days) since I

I am running Debian testing on my box. I had not used Python for about
a couple of weeks (during which I updated my system regularly) only to

below what happens

Perfect; that saved my day.
Many thanks

I am having a hard time with something which must be fairly doable: I

I put together this small snippet with the help I got on the mailing
