    7 >>> ax = subplot(111)

    Out[8]: [0.125, 0.10999999999999999, 0.77500000000000002, 0.79000000000000004]

You can change these values with ax.set_position.  This works whether
ax is an Axes or Subplot instance.

A timely question.  This feature was just added in the last release,
0.65

  >>> set(ax)  # lists all settable properties
  >>> get(ax)  # lists all properties and their values

Works for any matplotlib artist or sequence of artists; see
http://matplotlib.sf.net/examples/set_and_get.py

This is still a work in progress - the introspection works in part by
examining doc strings and I have finished porting all the artist
docstrings to the new format.  set(artist) should return a list of all
properties and their legal settable values.  If the settable values is
listed as unknown, it means I haven't done that docstring yet.

Also, I'm working on implementing Perry's suggestion of returning
silent lists where appropriate, which will help in pretty printing the
output, eg, of get(ax).

But it's mostly functional, as is.
