[Matplotlib-users] Nested Subplots?

[Tom J. <tj...@gm...>]

Is it possible to have nested subplots?

I would like to have 2 rows....with the top row having two columns and
the bottom row having one column.

For the bottom plot, I'd like to be able to choose between the following:
  1) The size of the bottom plot expands to fill the entire horizontal space.
  2) The size of the bottom plot is unchanged (same as the other two
plots) and is simply centered in the bottom row.

Thanks.
