Dear ferret users, I experience a little problem with the axis formats. I try to plot a file including 2 columns of LON LAT in the format -60.5 47.6, for example. I would like the axis to be in the format 60.5W 47.6N. I tried the command ppl xfor (f4.1, 'lonw') and ppl xfor (f4.1, 'lat') but it does not work. Would somebody have an idea to resolve the problem? Thank You in advance, Bye, Vincent --
