I doubt if overriding formatter works. Formatter basically does not know about the other coordinate. I think the easiest solution is to override the Axes.format_coord. For example, ax = gca() ax.format_coord = lambda x,y : "x=%g y=%g" % (x, y) x,y are in data coordinate. I'm not sure if there is any side effect, but it seems that the format_coord method is only used to display the coordinate in the toolbar. > Does anyone have any suggestions?

Take a look at the NavigationToolbar2 class in backend_bases.py. If you go down this road, you may need to modify mouse_move method to prevent it displaying the coordinate. You may use set_message method to display the coordinate. But I personally think overriding format_coord method is good enough.
