Dear All,
Thanks to what I found here

I discovered how to plot the convex hull around a set of points
(please have a look at the script pasted at the end of the email).
Everything is almost done,but I have a problem: my "points" are not
really point-like: they are sphere who
of matplotlib.
Keep up the good work.
Cheers

Hi,
And thanks for your suggestion. The improvement (if any) if
unfortunately rather modest.
I'd like to hear about the other "tricks".

Dear All,
I am concerned there could be a bug in errorplot for pylab.

than matplotlib CVS version) was to add

Dear All,
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

Dear All,
I would like to try out matplotlib for some basic 3D plotting.
First of all, is matplotlib suitable for that? I am asking since I read
on the website that matplotlib's selling point is 2D plotting.
What I would like to plot should be relatively easy: say that I have a
distribution (e.g.

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 parti
