[ncl-talk] Strange issue on plotting

[Joseph Clark]

Sorry for jumping in here. Perhaps set resources at cnLevelSelectionMode =
"AutomaticLevels". My guess is your data is out of the range on your color
bar on these days. I think the automatically generated color bar will tell
you what the range of your data values are.
