I really must try and disguise it more ;)  I did try and get hold of plotmtv
first, but then fell back on Excel (OpenOffice is much slower at graphing,
on this machine at least).

Outputting to .csv is one of the modifications I've made to mkgraph.py (diff
attached).  I'm not ready to check this in, though, because it makes the
script pretty ugly :)  I'll tidy it up somewhat (moving things into separate
functions rather than passing 'if' parameters) and then probably will.

There are three other changes that I made, which I will include in some form
when I check it in:
 1.  Added a docstring.
 2.  Added a -f command line arg to pass the file in ('mkgraph.py < file'
wouldn't work here, for some reason).
 3.  Output each set in one set of rows, with each line in a separate
column, rather than one line at a time.  The other way was workable, but
more effort to create a graph in Excel.
