Again, afraid not. At least nothing obvious. The legend placement is
done dynamically at draw time, and so it will be difficult to get this
information ahead of time. There might be some cleverness that can be
applied, but nothing easy.
One option would be connect to the draw event, and then inspect the
legend properties, and then place it where you want knowing the width
and the height. Not too elegant, but serviceable. Here is an
untested sketch
def ondraw(event):
if ondraw.done: return
# in pixels
left,bottom,width,height = leg.legendPatch.get_window_extent().get_bounds()
# move your legend
ondraw.done = True
ondraw.done = False
fig = figure()
ax = fig.add_subplot(111)
leg = ax.legend(blah)
fig.canvas.mpl_connect('draw_event', ondraw)
It might be better to patch legend directly to do what you want and
send the patch our way. Or subclass it.

It might be better to patch legend directly to do what you want and send the patch our way. Or subclass it. That does seem the way to go.

[Matplotlib-users] Scaling graph
Hi, I'm trying to draw a line given an angle, magnitude, x0 and y0 location on a 2d line plot. I use the cosine and sine to find the x1 and y1 locations so that I can draw a line segment from x0, y0 to x1, y1. This works fine on a 200 x 200 (Width x Height) pixel graph. However, I have an input form where the user can change the plot size, for example 200x800 or 800x200. The magnitude is along the y-axis and time is along the x-axis. At a particular point in time the magnitude and angle is given and I have to calculate the x1 and y1 values. The max magnitude along the y-axis (height) is always the same whether it is 200 pixels in height or 800 pixels in height. The scientist I'm working with wants to see the magnitude (x1,y1) of each plot look correct if the graph is 800 pixels or 200 pixels in height. He also wants the correct angle if you stretch the graph from 200 pixels wide to 800 pixels wide and then down to 100 pixels wide. I've been trying to use a ratio of the graph size to maintain the correct sizing but with no luck. Basically, the scientist want to maintain the same angle and reduce or increase the magnitude in the y-axis if the graph height is reduced or increased. Does anyone have an answer to this solution? Maintaining the same angle and varying the magnitude based on the y-axis height. Since, I have a lot of points I started to use a LineCollection to speed the rendering speed.
