Ah, thank you! I've worked it out now. In case anyone's curious:

code at http://topjaklont.student.utwente.nl/creaties/plothttplog.py
result at http://topjaklont.student.utwente.nl/eigenstats/bezoekers7x6.pn=
g
(updated nightly)

yours,
Gerrit.

P.S.
I've studies the .py sources at various places and saw a few places where
I though "this could be better" (for example, __future__ placed before
docstring doesn't work for docstring). I wanted to send a patch to SF but
SF's anonymous CVS is partially down so I couldn't do a cvs up. Is
Sourceforge patches page the correct place to send patches if I want to?
