[Matplotlib-users] TeX title and axe labels

[Dominique O. <Dom...@po...>]

First of all, i am blown away by the last two releases. Congratulations. 
I love TkAgg and the new TeX capabilities.

I have been feeling like a contour plot capability was missing from the 
current release. Since imshow is so much faster than pcolor, it would 
seem that it could do the job. How would you go about suppressing the 
colors altogether and plotting only the 'contours' (borders between 
different colors i guess)? If this is doable in a few commands, perhaps 
there could be a shortcut called 'contour', as in Matlab, to draw 
contour plots of a function of 2 variables?

Titles appear differently when they contain TeX commands, depending on 
whether or not they also contain regular text. For instance:

- title( r'$\rm{This is } \psi(\omega)$' )
   appears nicely, although the spacing in the "regular" text looks 
unequal on my monitor. But:

- title( r'$\psi(\omega)$' )
   alone, shows only the top of the symbols \psi(\omega)---it looks like 
the box that contains the text is placed too low, behind the plot. Same 
happens with [xy]label. Surprisingly, xlabel( r'$\omega$' ) works fine.

Also in the documentation for matplotlib.mathtext, are there dollar 
signs missing in the first example?

In the documentation for imshow(), i guess 'ColorMap' should actually be 
'Colormap' (lowercase m)?! I couldn't find any 'ColorMap'.

A final comment, using gca().set_yticks( ... ) prints a large number of 
messages "<matplotlib.axis.YTick instance at ...>". There must be a 
print somethere.

Great job!
