I just installed matplotlib-0.99.3.win32-py2.6.exe on this Win2000 PC.
When I try:
from matplotlib import pyplot as plt
it crashes Python with an apparent NULL-pointer reference. If I run
python -v
then it crashes just after:

Hi Guys,
I'm breaking my head how to use scientific numbering on color bar:
I use the following code to plot data from multiple files, would be great if
someone could direct me, becuase the numbers I have are 0.0013 et. and what
ever I do, the number just go over each other:
for i in

Hi,
I wanted to be more clear:
the numbers on my figure's color bar range from 0 to 1.7,
but mpl writes the following numbers:
0., 0.000250,0.50,0.000750,
etc.
This is totally not somthing I can use, it looks horrible.
I'm also attaching the image ...

found a solution after 2 hours ...
colorbar(ax=ax1, orientation='horizontal',format='%.3f')
now, I need to know how to set up limits for all the images which are
exactly the same limits.
So far I'm failing with the use of boundaries
Would be happy to know

Oz,
Some plotting functions like pcolor and imshow have keyword args for
vmin/vmax where you can explicitly set the min and maximum values for the
colorscale. There are some more complicated things you can do with the
colormap that are more generic to all plotting functions as well, but I
would
Hi Thanks for the answer,
actually, I always use
show and plot, I have no clue how to use the functions you suggested ...
I'll look into it.
Do you have an idea where I can find a description of the keyword format
'%.3f' is nice, but still not scientific format...
is this like Fortran?

hi andre,
thanks for your reply,
do you know where I can find more documentation about this ?
Thanks,

Hi Oz,
Sorry, I am not familiar with what you are trying to do with your
plots. Everything I have learned is from trial and error, the gallery
page
http://matplotlib.sourceforge.net/gallery.html
and the user manual
http://matplotlib.sourceforge.net/contents.html
Good luck,
Andre
Hi,
I open another thread because I think this is not related.
I have figured out how to create scientific notation in the color bar.
However, by default Python creates really ugly values for printing:
1.165E+00, 1.167E+00... etc.
I figure that they are stored somewhere in a list.
I could do :
Yeah, I don't think that is what you want. I believe the 'ax' you are
referencing there is the figure axes. How do you want the numbers to
appear?

right now doing somthing like this:
