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.
