[ncl-talk] About ' cnConstFEnableFill '

[Toni Klemm]

Hi Soares,

I’m not totally sure what the problem is. It might have to do with   res at cnLevelSelectionMode = “ExplicitLevels”  in your script. This says you want to provide “explicit levels” (= specific numbers) for your legend bar categories, but you don’t do that. Try commenting out that line using “;” or change it to ManualLevels if you know the range of values in your plot. Maybe that’ll give you your map. Search for it here (https://www.ncl.ucar.edu/Document/Graphics/Resources/cn.shtml <https://www.ncl.ucar.edu/Document/Graphics/Resources/cn.shtml>) if none of this works.

Best,
Toni
