     * :class:`AutoDateLocator`: On autoscale, this class picks the best
-      :class:`MultipleDateLocator` to set the view limits and the tick
-      locations.
+      :class:`RRuleLocator` to set the view limits and the tick
+      locations.  If called with ``interval_multiples=True`` it will
+      make ticks line up with sensible multiples of the tick intervals.  E.g.
+      if the interval is 4 hours, it will pick hours 0, 4, 8, etc as ticks.
+      This behaviour is not garaunteed by default.
