ax1 = subplot(121)
ax2 = subplot(122, sharex=ax1, sharey=ax1)
ax1.set_adjustable("box-forced")
ax2.set_adjustable("box-forced")
arr1 = np.arange(100).reshape((10, 10))
ax1.imshow(arr1)
arr2 = np.arange(100, 0, -1).reshape((10, 10))
ax2.imshow(arr2)
Note the use of set_adjustable("box-forced").
sharex and sharey does not get along with axes of aspect=1 & adjustable="box".
