+    "Since HoloViews objects nest in a variety of ways and you do not want to keep changing the options specification when you compose your object into an ``Overlay`` or ``NdOverlay``, certain ``plot`` options are inherited. This includes all plot options which control the appearance of the axes, but not those that are specific to the Element. As a simple example let us combine the ``Image`` from above with some ``Bounds``. Even though we apply the ``xrotation`` and ``yticks`` options to the ``Image`` they are inherited by the ``Overlay`` of the ``Image`` and ``Bounds``."
