Yep, saving the plotting system variables is exactly what you do. Its not that
bad, however. The following simple-minded way will suffice.
x = findgen(100)/10.0
y = exp(-0.1*x)*sin(4*x)
plot, x, y
;save the settings
pstate0 = !P
xstate0 = !X
ystate0 = !Y
zstate0 = !Z
wset, 1
y = exp( 0.1*x)*cos(4*x)
plot, x, y
;save new settings
pstate1 = !P
xstate1 = !X
ystate1 = !Y
zstate1 = !Z
;now proceed to overplot at will :)
wset, 0
;restore old settings
!P = pstate0
!X = xstate0
!Y = ystate0
!Z = zstate0
oplot, x, 0.1*X
etc, etc. As usual, there are more complicated ways of doing this, but you
get the idea ;)
