I am not absolutely sure if I got your problem right,
but I once wrote me the following two progs:
;
;file: getplot.pro
;
; A. Lodwig, 3/95
;
pro setplot,a
!p = a.p
!x = a.x
!y = a.y
!z = a.z
end
function getplot
ret={,p:!p,x:!x,y:!y,z:!z} ;create an unnamed structure
return,ret
end
Just draw your first plot, then do plot1 = getplot(),
do your next plot, then plot2 = getplot() and so on.
If you wish to oplot in one of the previous plots, say
the second one, you have to do 'setplot, plot2' and all
status variables are restored.
I didn't need window switching, but you should be able
to add this to the progs.
Hope this helps,
Andre

You have to save the plot parameters established for the various
windows if you want to go back to those windows (plots, really)
and overplot on them. In practice this usually means keeping
track of the !P, !X, and !Y system variables for each window.
The sequence of commands might look like this:
; Plot first plot in window 1. Store plot parameters.
Window, 1
Plot, data
p1=!P & x1=!X & y1 !Y
; Plot first plot in window 2. Store plot parameters.
Window, 2
Plot, moredata
p2=!P & x2=!X & y2 !Y
; Return to window 1, restore window 1 parameters and overplot.
WSet, 1
!P=p1 & !X=x1 & !Y=y1
OPLOT, stillmoredata
Cheers!
