object-oriented interface

Could someone point me to documentation of the oo

    > interface? Everything seems to reference pylab (even
    > examples that say they're for the oo interface).

  http://matplotlib.sourceforge.net/faq.html#OO

and

  http://matplotlib.sourceforge.net/leftwich_tut.txt

and examples:

  > ls agg_oo.py embedding_in_*
  agg_oo.py
  embedding_in_gtk.py
  embedding_in_tk2.py
  embedding_in_wx3.py
  embedding_in_gtk2.py
  embedding_in_qt4.py
  embedding_in_tk.py
  embedding_in_wx4.py
  embedding_in_gtk3.py
  embedding_in_qt.py
  embedding_in_wx2.py
  embedding_in_wx.py

There is also a chapter in the User's Guide on the web site on the
API....
