Re: [ferret_users] How to draw a box to represent the regional-scale study areas in a field over a larger area?

Hi Yun,
                       There is another way too that is 
go box  Min_LON MAX_LON MIN_LAT MAX_LAT LINE number(optional)
go box 50 60 5 10 13 will draw a box in Arabian sea  with thick black line.

Do you mean to cimple draw lines and boxes over an existing plot?
One easy way to do this is to list your points in a plot/vs command:

plot/vs/over/nolab/line=8 {115,120},{-30,-35}                   ! thick red diagonal
line

plot/vs/over/nolab/line=10 {135,140,140,135,135},
{-32,-32,-36,-36,-32}     ! thick blue box

Or do you want to blank out the filled areas outside the region? Then
use masking. It's in the documentation.
