That's probably possible to get some limited interaction, however 
I'm not sure it would very satisfactory or complete. For example 
is it possible to have a live updating rectangle displayed as one 
drags the mouse to select a region to inspect? Is it possible to 
display a slider which can be dragged by the mouse to update 
values on the plot or have a drop down menu to select a data 
series? It seems it may also be difficult to find a way to have 
elisp interact with the matplotlib fast enough to not introduce 
noticable delay as such actions update the view.
