Re: [ferret_users] how to plot only one GRAT line at the x-axis

[Ansley Manke <ansley.b.manke@xxxxxxxx>]

Hi Yogesh,
There is a command PPL CROSS which draws a single horizontal line at y=0 
and a vertical line at  x=0. It is a setting that remains in effect for 
the entire session or until it is turned off.  It works for all plots in 
1 or 2 dimensions.

 ppl cross 1  ! turns on the lines at x=0,y=0
 plot w1, p

 shade u2       ! the lines are still drawn

 ppl cross 0   ! turns off the lines at x=0,y=0
 plot s2, m
