Hi,
I would like to create a figure which only contains a legend, and no axes
at all. I would like to manually assign the colors. I found this here:
http://stackoverflow.com/a/3302666
but from there on, I'd like to remove the axes, and put the legend into
three columns.
Any help is greatly appreciated 
Andreas.

If the plot attached it's fine for you it's easy:
import matplotlib.pyplot as plt
ax = plt.subplot() #create the axes
ax.set_axis_off() #turn off the axis
.... #do patches and labels
ax.legend(patches, labels, ...) #legend alone in the figure
plt.show()

That's really easy I could live with this solution, applying some
external tool like pdfcrop to the result. Of course, it would be nicer if
the PDF's page size would be exactly that of the legend (plus some
margin), so that I wouldn't have to resort to external tools ...
Any ideas?
Cheers, A.
If you can use other output, you can generate a png image, which would
be easier to cut (even inside MPL.image). This, without entering in
more complicated issues, that I don't know if they are even possible.

How about
plt.savefig('roflcakes.png', bbox_inches='tight', pad_inches=0.1)
Since the other artists are invisible, that should crop to just your
legend. I'm assuming matplotlib updates the BoundingBox such that it
doesn't include invisible artists.

Hi,
you should be also able to create the axes as:
ax = plt.figure( figsize=(x,y) ).add_subplot(111)
with figsize big enough to fit just the legend
Cheers
Francesco

Thanks for your help, guys! I wasn't totally happy with the 'tight'
bounding box, as the margins to the legend were not uniform on all four
sides. So I did indeed return to a subprocess.call(['pdfcrop', ...]).
Cheers, A.
