Re: [ferret_users] grid offset?
Thanks for the reply. The revised syntax you suggested (setting the
region explicitly) works. So
let diff = var_sim-var_obs
fill/level=(-10,10,1)/pal=light_centered/nolabel/set diff
[i=6:33,j=6:33],x_page[i=6:33,j=6:33],y_page[i=6:33,j=6:33]
ppl shakey ,,,,,,,,1.40,5.25; ppl fill
works, and
let diff = var_sim[i=6:33,j=6:33]-var_obs[i=6:33,j=6:33]
fill/level=(-10,10,1)/pal=light_centered/nolabel/set diff,x_page,y_page
ppl shakey ,,,,,,,,1.40,5.25; ppl fill
go mp_land_proj 1 " " 1 1
does not.
Thanks again for the fix.
