matplotlib-users Mailing List for matplotlib

Hi all.
I have tried to add fractions, superscript and some other symbols in
axis labels using latex or mathtext. But then they are different to
much from other text.
Is there any trick to make them look the same?
Thanks.
Petro.

I think you forget to set the layout on your central widget.
self.main_widget.setLayout(vbl) # in your case

You can call QuadMesh's `set_array` method, just as you can for images.
(You suggest there is no set_array method for QuadMesh; are you sure about
that?) The strange part is that it expects a 1d array, where as colormesh
accepts arrays of various dimensions.
>>> import numpy as np
>>> import matplotlib.pyplot as plt
>>> mesh = plt.pcolormesh(np.random.rand(10,10))
>>> mesh.set_array(np.random.rand(10,10).ravel())
>>> plt.draw()
set_array doesn't complain if you remove the call to `ravel`, but
`plt.draw()` will complain.

Hi,
I have plt.pcolormesh plot i would like to animate. So i've taken a
look at the various examples and decided to go with the FuncAnimation
routine. This works for me, but im using for every frame a new call to
plt.colormesh and i am not updating the underlaying data, like in this
example
http://matplotlib.sourceforge.net/examples/animation/dynamic_image.html
This is because there seems to be no set_data, set_array or similar
for the from plt.colormesh returned object (an instance of
matplotlib.collection.QuadMesh). Am i right? Is there any way i can
update the data structures of plt.colormesh?
I know i could use a ArtistAnimation like in
http://matplotlib.sourceforge.net/examples/animation/dynamic_image2.html
but i don't want to cache so many images.
Thanks!
