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