[Matplotlib-users] aligning multiple legends

[Paul I. <piv...@gm...>]

I want to have two legends (from different axes) positioned right up
against on another.

Here's a static example, except I want the second legend to be defined
relative to the first (if leg is moved, I want leg2 to move as well). I
can't seem to figure out the proper bbox_to_anchor and bbox_transform
parameters to pass to the second legend() to make this work.

# small example
ax = plt.subplot(1,1,1)
ax2 = ax.twinx()
ax.plot([0,1], label='ax1')
ax2.plot([1,0], 'r--',label='ax2')
leg = ax.legend(loc='lower left', borderaxespad=0,
	bbox_to_anchor=(.85,.85))
leg2 = ax2.legend(loc='upper left', borderaxespad=0,
	bbox_to_anchor=(.85,.85))

thanks in advance,
