Thread-topic: [ferret_users] ppl for levels

Hi Ansley,

Thanks so much for your reply. That is why I could not find anything.. I am try to remove everything(label, title) and customize a shade plot using ppl. I have tried doing this but the colors are different (the palette goes from purple to yellow-orange instead of red). If I remove the comment /nolab/set.... the color plot works perfectly fine. So there is something which it is not well coded.

shade/levels=(-inf)(0.2,0.5,0.01)(inf) /nolab/set_up my_varaible; ppl title "Title";ppl shade ;\

Kind regards

Estanislao

Hi Estanislao,

LEVELS is not a PPLUS command but a qualifier on the Ferret plot commands which use color palettes. (PPLUS in its original form did not have color-filled plots, but only line, vector, and contour plots.)

The LEVELS settings are documented here: http://ferret.pmel.noaa.gov/Ferret/documentation/users-guide/customizing-plots/CONTOURING#_VPINDEXENTRY_852 The same options and settings apply to FILL, SHADE, POLYGON and RIBBON plots.

6.8.1.1 /LEVELS qualifier The /LEVELS qualifier for CONTOUR, SHADE and FILL commands is a powerful and multi-functional tool. It takes the form /LEVELS ...
