Hi...I am a new user and I need some advice...
I have 3 array of data (270 X 406) containing latitudes and longitudes
and pressure. I make the proper contour but I want over it to put some
black points showing values of latitude and longitude which I will take
from another array but belong to the same limit area defined in my
contour...how can I add these points according to their geographical
coordinates?

Do you try OPLOT?
If you write:
aux=sin(indgen(50,50))^2
contour,aux
oplot,sort(randomu(0,20)),psym=1
you have the contour and a sort of points in the same coordinate system.
I think this is what you want.
