In IDL, you really have to decide if you are going
to turn control over to !P.Multi (or WMulti, if you
are using cgWindow), or you are going to position
plots yourself with !P.Position. You can't
have your cake and eat it, too.
Another alternative, of course, is to use the Layout
keyword. You have a LOT more flexibility with Layout,
as long as you realize you can NEVER erase anything
when using it!
In this case, you probably have to choose your poison. :-)
Cheers,
David
