Re: [ferret_users] How can I use ferret to plot a shading (or stippling) area

[Thomas Froelicher <froelicher@xxxxxxxxxxxxxxxx>]

Hi Liya,

please find below the commands to plot a stippling area which is
statistical significant for two fields

----------
! Define mask (1) for significance
let significance = if ... gt 0.95 then 1 else 0

let lon = x[gx=temp] + 0*y[gy=temp]
let lat = 0*x[gx=temp] + y[gy=temp]

fill temp  
plot/nolab/vs/over/sym=dot/color=black  significant*lon, significant*lat
-----------

Cheers,

thomas
