Contour from ascii data file

[Francisco Pastor <paco@xxxxxxx>]

    Hi ferreters

    I am trying to make a contour plot from an ascii data file with
three columns (lat, lon, data). I've searched through the users guide
and the mail archive but can't find the way. Has any of you done
something similar? I'm using Ferret version 4.4 in HP-UX.10.20

    Any help would be greatly appreciated, thanks in advance.

    Paco
