[ncl-talk] How to change the no data region color in contour plot

[Mary Haley]

Yun,

I think you could simply set both mpLandFillColor and mpOceanFillColor to
"gray". mpFillOn needs to be set to True for this to work.

If the gray is appearing on top of the contours, then you can further try
setting mpFillDrawOrder to "Draw" or "PreDraw".
