A little birdie has told me that someone else is writing a new comprehensive matplotlib book (I think it would replace Sandros' book). Last I heard from the birdie, he was most of the way done with the manuscript. Based on my experience with the edit/review process, I would guess 2-3 more months to see it finished and published.
