Re: Plotting Colors for Missing Values

Hi Melissa,

Thanks for the script and data.

The problem is that the missing value fill color setting was never
working, because you need to also set:

   res_at_cnMissingValFillPattern = "SolidFill"

(The default is "hollowfill".)

The "green" fill you were seeing is from map fill. It is green
because (as Adam stated earlier) the gsn_csm_xxx_map scripts try to
fill the land area in "gray", and if your colormap doesn't have
"gray", the next closest color will be used.

I believe V5.0.0 of NCL had a bug in it in that affected map
fill being used with the high-res database. That's why you were
seeing "white" when using 5.0.0.

So, the short of it is, you need to set:

   res_at_cnMissingValFillPattern = "SolidFill"
   res_at_cnMissingValFillColor = "white"

I will make sure the resource documentation is more clear on this.
