Problem

In situations where anAxes has a large background image/map (extent greater than axis limits) and the axis limits are supposed to be controlled by other artists, like paths, it would be very helpful to have toggling parameters likescalex andscaley as inAxes.plot. Right now, even if you fix the limits afterimshow, the moment you let autoscale do its thing (which is desired) it rescales to show the whole image.

Proposed Solution

A very simple and probably naive solution would be to wrap theimshow line below in anif wherescalexy isTrue by default:

ifscalexy:im.set_extent(im.get_extent())
