Well, you will have to fix your axis labels. Perhaps a
YTICKFORMAT function that adds the offset back in.
The thing about IDL is that just when you've lowered
your expectations enough, IDL turns around and does
something fantastic with no effort at all. This makes
your expectations rise again, etc. I try to practice
the Buddhist attitude of "no expectations". When I
manage to do it correctly I find myself in a state
of constant surprise, no matter what happens. :-)
Cheers,
David

A solution to get the "beautifull" line is just:
IDL> plot, s-min(s), /ynozero
But doing so the y axis labels are wrong. And I thought IDL was clever
enough to handle this properly. In fact this is my main error: I'm
excepting too much from IDL. :-)
Later.
Nicolas.

No, I think you are just applying analog thinking to
a digital solution. :-)
Cheers,

P.S. Perhaps a scaling factor to "spread" these
values out some. :-)
