[ferret_users] glitch in automatic shade color levels

["Riede, Hella" <hella.riede@xxxxxxx>]

Dear ferreters,
 
I discovered a glitch in the automatic shade color levels, see shade_nolev_gap.png, where a grid box in the northeast of India is not colored. When I plot the same variable with a scaling factor of '1e9', the coloring appears, likewise when I specify levels by hand accordingly.
 
I attached the file 2D_test.nc for testing purposes.
 
!! plot with gap
yes? shade co_emac; go land
 
!! gap disappears with scaling
yes? shade co_emac*1e9; go land
 
!! gap disappears with suitable levels
yes? shade/lev=(40e-9,200e-9,10e-9) co_emac; go land
 
!! similar example with a different variable
yes? shade co_mix; go land
yes? shade co_mix*1e9; go land
 
 
 
Any background on this?
 
 
Best wishes,
Hella
