Hi Ben,

actually I would like to send you an improved version but there is an
issue that I can't solve:

I add the listeners for each subplot as I described in my previous mail
and everything works fine, until I plot something on the subplot axes.
The plot command calls "set_defaults" which in turn removes all
listeners.

How could I make the listeners persistent? Do you have any clue?
