Hello Marco,
thanks for your reply (and sorry for my late one)

And that's fine, because the audience of the book is people that have
never seen matplotlib and wanted to learn it.

Just out of curiosity: how do you refresh those plots? in a loop
closing/opening the figure or clear the figure and replot on it? are
those graphs embedded in an application or are just "shown on screen"?

Indeed, that's one of the reason for its use in so many scientific
environments.

Yes, we will show the "class" interface during the examples, while
showing the difference just for the sake of completeness.

as already said, this bug is intended to people that knows nothing
about mpl, so an introductory part will begin the book.

and we will try to show as much features as possible, even the
advanced one.

Those will be surely in the book :)

Well, whatever comes to mind, please let me know :)
