+Axis and Locator ``pan`` and ``zoom``
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+The unused ``pan`` and ``zoom`` methods of `~.axis.Axis` and `~.ticker.Locator`
+have been removed.  Panning and zooming are now implemented using the
+``start_pan``, ``drag_pan``, and ``end_pan`` methods of `~.axes.Axes`.
