I don't know why at the moment, but I've always been in the
habit of saving !X, !Y, and !P. I *think* there is something
in !P that also needs to be restored when moving from one
plot to the other, but maybe this is one of my old wive's
tales. ;-)
Cheers,

Just save the !X and !Y system variables and reset them before
oplotting:
window,1
plot,...
x1=!X & y1=!Y
window,2
plot,...
x2=!X & y2=!Y
window,3
plot,...
x3=!X & y3=!Y
...
wset,1
!X=x1 & !Y=y1
oplot,....
...
Good luck,
JD
