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! :)
