[ferret_users] Plotting a simple box outline?

[Luke M <coding1227@xxxxxxxxx>]

Hi everyone,

I'm trying to plot a simple box outline over a map to show the location of a particular area. Using Ferret v6.82, if I do the following command, I get a nice box outline over southern Australia:

set region x=100E:100E/y=-90:90
yes? go fland 20 white
go fland
plot/vs/over/nolab/line=10 {-135,-140,-140,-135,-135},{-32,-32,-36,-36,-32}


However, I am having difficulty trying to plot the following two boxes:

a. over the south-central Pacific Ocean (160W through 100W, and 40S to 20S)

b. over the British Isles (5W through 5E, and 45N through 60N)


Any suggestions on how I can do this?

Thanks!
