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

Hi NCL users,

I have a two dimensional array. This array has lat2d and lon2d attributes. If the lat2d, lon2d covers latitude from 0-5 N degree, longitude 0-5 E degree, When I do the contour plot, I set the mpMinLatF, mpMaxLatF, mpMinLonF, mpMaxLonF bigger than lat2d lon2d range (for example latitude from 0-10 N degree, longitude 0-10 E degree ). Now the region without data is filled with white color in NCL. But I want to change the region without data as gray or other colors. It looks like cnMissingValFillColor won't work at here. Does anyone know how to solve this? I appreciate any help.

Thanks very much,

Yun
