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!
