Have a look at my plot_text program, which allows you to position text
underneath a plot (or inside a plot). For example, try this:
!p.multi=[0,1,2]
plot,[1,2],ymargin=[10,2]
plot_text,['Some text','Some more text'],position=1
plot,[1,2]
You can also use my legend program to position a plot legend the same
way.
The plot_text and legend procedures are part of the 'windt library',
available at http://www.bell-labs.com/user/windt/idl

All true, but NOT, I think, with !P.Multi. For one thing, the
!X.Window parameters are not set until *after* the plot is
made. It would be possible, probably, to use !P.Multi to do
some of the nasty calculating for you. Especially with respect
to calculating the proper character size, etc. for the plots.
I did something similar with a complicated plot object I
created some time ago that had to plot itself into a window
grid. But the actual plots were drawn with the parameters
that I got from !P.Multi, not by using it directly.

!P.Multi is beautiful. In fact, more beautiful and useful than
most people realize. But I still think it is not the correct
choice for this particular application.
Cheers,
David

Hey David!
Wasn't it you yourself who told me about !x.window and !y.window which store
the size of the current plot window? As a first try you could position your
text with something like
px = (!x.window[0]+!x.window[1])/2.
py = !y.window[0]
xyouts,px,py,yourtext,/norm,align=0.5
and if you use the !x.margin and !y.margin keywords, you may even be able to
prevent the plot and the text box from running into each other.
The beauty of !p.multi is that you can easily specify the number of rows and
columns without having to go through these non-trivial calculations of the
position parameter. I don't think one should drop this too fast.
Regards,
Martin.

I think you may have to give up on !P.Multi in this case,
unless you are really, really clever (and even then I'm not
sure you could do it or that it would be worth the effort).
I think it would be much easier to just position the plots
in the window yourself. Subsequent plots can be drawn into
the window with the NOErase keyword.
Cheers,
David
