[Matplotlib-users] New user of matplotlib : some problem with version 0.62.4

[Jean P. <2s...@ma...>]

Hello,

I'm a new user of matplotlib and I have to admit that I'm quite
impressed and excited about it !
I'm currently trying to convince the whole company to switch from matlab
to python (at least 200 users I think), and matplotlib is a big asset.

If it's a success, as a big supporter of free software, I hope to
convince the company to make some donations to python and/or
matplotlib...(matlab licence are really expensive...)

Anyway, at the moment I can't make any donation, but I can at least help
to improve matplotlib, so here are the problems I've found :

I began with version 0.60.2 and everything worked out of the box with
either linux or windows NT4.
But when trying to display several plot on the same window, I had some
text overlapping so after a while I've decided to switch to 0.62.4 to
see if things has improved.

But it seems that everything was broken ! I cannot even display a
simple plot on windows NT4 or linux.
On windows I use the enthought edition python-2.3.3-1057 and on linux I
was using the latest (python 2.3.4, wxPython 2.5.2.7, numarray 1.0,
Numeric 23.3...).

Here is the output on linux when I try to use the simple_plot.py :

Let me know if I can do anything to help you understand the problem... 

Anyway, great software !
