matplotlib-devel Mailing List for matplotlib

I mailed this to the matplotlib-users list, but it never showed, so
I'm trying this one. Apologies
if it shows up in both places :(
What I'm trying to do can be boiled down to the following: I'm trying to
place a legend precisely, using the top left corner of legend as the
"sticky" point. In other words, if I want to place the legend here:
+---------------------------------+-----------+
| | |
| | legend |
| | |
| The plot... |-----------+
| |
| |
| |
| |
| |
| |
| |
+---------------------------------+
I would have thought that I would set bbox_to_anchor = (0,0,1,1), and loc =
(1,1). I found out quickly, though, that this places the legend like this:
 +-----------+
 | |
 | legend |
 | |
+---------------------------------+-----------+
| |
| |
| |
| The plot... |
| |
| |
| |
| |
| |
| |
| |
+---------------------------------+
Which makes perfect sense from matplotlib's perspective. So all I need to
do is figure out how tall the legend is, and subtract that off the y
coordinate before passing 'loc' off to matplotlib's legend. I just can't
seem to figure out how to get that number. I tried
self.ax.get_legend().get_frame().get_height(), but that just returns 1 all
the time. I browsed all through the legend object (a live one) and just can't
find any numbers at all that look like the legend width/height, in any
coordinate
system. I hope I'm missing something obvious!
Ascii art is fun! :)
