Partial camera linking
======================

You can customize the camera axes that a controller acts on. In this example with two subplots you can pan and zoom 
in x-y in each individual subplot, but only the x-axis panning is linked between the two subplots. The y-axis pan 
and zoom in independent on each subplot.
