For the location events (button and key press/release), if the<br>
mouse is over the axes, the variable ``event.inaxes`` will be<br>
set to the :class:`~matplotlib.axes.Axes` the event occurs is<br>
over, and additionally, the variables ``event.xdata`` and<br>
``event.ydata`` will be defined. This is the mouse location<br>
in data coords. See<br>
:class:`~matplotlib.backend_bases.KeyEvent` and<br>
:class:`~matplotlib.backend_bases.MouseEvent` for more info.<br>
<br>
Return value is a connection id that can be used with<br>
:meth:`~matplotlib.backend_bases.Event.mpl_disconnect`.<br>
