I don't know enough about OpenGL, but I wonder if it would really help 
much, as much of the scaling, etc, it happening in MPL code anyway. It 
could be great for future stuff with more 3-d though.
VTK is worth a look for you, as well.

Thank you very much!!!
I used scipy.integrate tools, splitting complex and real part of the
equations, and it worked so good!!
I tried to use: In addition I have filed a ticket for a complex ODE solver.
http://projects.scipy.org/scipy/scipy/ticket/334
But I haven't been able to compile it. It returns a lot of errors when I
tried. I suposse that it's because of the fortran compiler, but I don't
know.

Hi,
I'm looking into using matplotlib as the backend for doing visualization 
for my dissertation work. This would replace some existing Qt/OpenGL 
code I've written (but isn't too extensible) for 2D plots of weather 
radar data (think pcolor style plots). I've been using matplotlib for 
awhile for other projects, and love it, but it has the drawback that 
it's interactive graphics are not all that quick (especially pcolor). 
(Note: I know imshow is faster, but my data are on a polar grid.) I've 
been spoiled by the speed of OpenGL graphics and the ease of interactive 
data analysis, so I just can't go back. Has anyone tried making an 
OpenGL backend? If not, can anyone think of any reason why it couldn't 
be done, maybe using wx's GLCanvas?
Any comments, or starting points on where I could see how to go about 
this would be _greatly_ appreciated.
Thanks,
Ryan

Thanks for you advice.
I asked because I thought that this __revision__ is the matplotlib.__revison__ 
that I get e.g. in IPython. That's why I thought it should be the revision of 
the whole project.
Just a remark - you can forget about it.
best regards,

It hasn't changed since rev 3131:
$ svn info __init__.py | grep 'Rev'
Revision: 3257
Last Changed Rev: 3131

Hi devolopers,
one small remark about the mpl svn. I recognized, that in the 
file ./lib/matplotlib/__init__.py the actual revision is: 
__revision__ = '$Revision: 3131 $'
and the svn info tells "Revision: 3257".
best regards,
Matthias 

Hi everybody,
I use key_press_event's to handle my program.
Therefore I want to skip the matplotlib usage of some keys e.g. 'f', 'g' 
and 'l'.
I didn't find the right method to turn the usage off. Can anybody help me?
 
Could this method be useful for buttons and sliders from widgets.py, too?
Because one don't want to scale or set grid upon these widgets, isn't it? 
best regards and thanks in advance for any hints,
Matthias

rk4 was something I wrote long ago to have a simple ODE integrator in
case scipy wasn't installed on my system. You should be using the
scipy.integrate tools

hi everyone,
I'm trying to solve a lineal differential equation system, and I,m proving
with the mlab.rk4 function.
The problem I've found is that if the solution if a complex number, I can't
use this functin, because it doesn't accept complex number, and I can only
get the real case.
Have anyone treat with this problem?
What do you use to solve differential equation systems?

colorbar returns a matplotlib.colorbar.Colorbar instance. This has an
Axes attribute attached as "ax", eg
 cb = fig.colorbar(...)
 cb.ax.set_xlabel('etc')
but you should look at the class methods available in the Colorbar
class proper. Eg, Colorbar.set_label will set either the xlabel or
the ylabel depending on the orientation.
