Re: [Matplotlib-users] Fixing axes for imshow plot on top of a figure

I do not think fig.add_axes([0.1, 1, 1, 1]) makes any sense. The docstring says:

fig.add_axes(*args, **kwargs)

Add an axes at position *rect* [*left*, *bottom*, *width*,
*height*] where all quantities are in fractions of figure
width and height.

If bottom and height are both 1 you need the height of the figure to
be 2 in fractions of figure height. This means 1 must equal 2 and then
Bertrand Russel must be the Pope[1].
