Calling cla or clf in the animation loop is probably always a bad
idea, because of the flashing you have noticed. Trying to use a simple

Hello,
Is there an easy way to make a legend with multiple lines
and columns? I need 8 plots in the same figure, and the
legend takes a lot of space. I believe that if I could
orient the legend in multiple lines and columns (say, 2
lines with four columns each), I could save a lot of
space, giving
The current legend class does not support multiple columns.
Eric Wertman once mentioned in this list that he would work on this
feature, but I don't know the current status.
A (partial) rewrite of the legend class which I plan to support
multicolumns is in my TODO list but I haven't started it yet.
Hi Sebastien,
Sorry, I had forgotten about that. I've taken a look at the code that we have
... and it doesn't separate out nearly as much as I had thought. The code that
rebuilds the plots is actually pretty complicated and messy ... not so much
from a conceptual point of view but in how it
Hi,
I can do everything I want with pylab (and even more :) ).
I'm only missing one thing:
I really would like to have one more option in imshow to get the pixel
value of the pixel pointed by the cursor.
The backends are showing X qnd Y coordinates. It is fine but I need also
to look at the pix
Hello,

Thanks for your answer. That did the trick, and the figure
looks more or less as I wanted. It would look exactly as I
wanted if I could remove the border
Although I think it is possible to calculate the bounding box of the
all legends automatically,
Here is a manual way.
from matplotlib.patches import Rectangle
l1.get_frame().set_visible(False) # make background frame of legends invisible
l2.get_frame().set_visible(False)
# make a large backgrou

Hi
Are there any modules in matplotlib for coordinate transformations. In
particular, I want to go from geodetic to WGS-84.
Thanks
