You can manually turn off autoscaling on the axes instance with the
following, and both scatter and plot should then work as you want.
ax1 = subplot(121)
axis('off')
ax1.imshow(rand(20,20))
ax2 = subplot(122)
axis('off')
ax2.imshow(rand(20,20))
ax1.set_autoscale_on(False)
#ax1.scatter([5,10],[5,10]) # note 2
ax1.plot([5,10],[5,10], 'o') # note 3
show()
