Hi,
If you have 2 different plots in two different windows,
what you need to do is save the !P, !X and !Y system variables
between plots. For example:
wset,1
plot,x1,y1,psym=4,xrange=[5,15],yrange=....
savep1=!p
savex1=!x
savey1=!y
wset,2
plot,x2,y2,...
savep2=!p
savex2=!x
savey2=!y
;Now to plot another point in plot 1:
wset,1
!p=savep1
!x=savex1
!y=savey1
oplot,x1_new,y1_new ;or plots or whatever.
:
:
:
etc
I don't know if this will work with both plots in the same window (you
might need to do stuff with the position keyword)
Hope this helps,
Larry
