Re: Shade land in oceanic plot

Hi Vinit,
If the data over land = _FillValue, as I am guessing yours is, then all
areas set to _FillValue are color filled with the background color, in
most cases white.

You have two choices that I can think of:
1) If the resource applies, and you are not setting cnFillMode =
"RasterFill", then you can set cnMissingValFillColor = "transparent".
http://www.ncl.ucar.edu/Document/Graphics/Resources/cn.shtml#cnMissingValFillColor
Make sure mpLandFillColor = "black"

2) Again, set mpLandFillColor = "black", and then set mpFillDrawOrder =
"PostDraw", which will fill the land last, covering up whatever data
color fill was present over land.

Others might have other suggestions..
Good luck,
Adam
