Thanks for the example -- you are right that this is a 'legacy' event callback outside the regular event framework. So it doesn't really belong in the event handling chapter but may merit a quick note there. Alternatively, we could rather easily draft up a special event (NavigationEvent?) that *does* work in the regular event handling framework. The quirk is that the events are handled at the canvas level, so it would be difficult to register for a single axes, but one could get a NavigationEvent if the limits of any of the axes in the figure were updated, and use the inaxes attribute to process it. If this, or some variant of it, seems like a good idea I'm happy to add it.
