add sheet and image via python?

[Christopher Peters <CPeters edisonmission com>]

Hi,

I'm trying to run Python scripts through
Gnumeric, and was wondering if there was a way to add worksheets to a currently
open workbook using a Python command.  For example, I have

wb = Gnumeric.workbooks()[0]
sh = wb.sheets()[]

I would like to run a Python script,
and pipe the output to a new sheet, say Sheet4 (as opposed to the 3 already-open
sheets in wb), without opening the new sheet explicitly using the Gnumeric
spreadsheet program.

Also, is there any way to import a graphic
using a Python script?  I will be making my charts/plots using matplotlib
(in pylab) and want to display them in Gnumeric.

Any help that anyone can give on this
would be greatly appreciated!

Cheers,
Chris
