Re: black and white and color shading polar plot without grid lines

Hi Waqar,
Grays range from dark ("gray25" for example) to light ("gray90" for
example). See the named colors page here:
http://www.ncl.ucar.edu/Document/Graphics/named_colors.shtml

If you are using NCL version 6.1.0, you can ask for a named color and it
will be automatically added to your colormap and is available for you.
If you are using a previous NCL build, you will have to have defined a
colorbar with the shade of gray you are calling for in it (see the
gsdtol colormap for instance here:
http://www.ncl.ucar.edu/Document/Graphics/ColorTables/gsdtol.shtml) or
you can individually add the color to your colormap using NhlNewColor
and specifying constant RGB values like .3,.3,.3 for gray30 for
instance. (See:
http://www.ncl.ucar.edu/Document/Graphics/ColorTables/gsdtol.shtml ).

With regards to the line label contour, I was going to point you to the
Contour Labels example page (http://www.ncl.ucar.edu/Applications/ ->
Contour Labels ) but there wasn't an example on how to do this. The
resource you are after is cnLineLabelFontColor:
http://www.ncl.ucar.edu/Document/Graphics/Resources/cn.shtml#cnLineLabelFontColor

Finally, with regards to the resources not working, setting
res@mpGridAndLimbOn = False and res@gsnPolarLabelFontHeightF = 0.0
should work. I noticed that in my original reply I typed mpGridandLimbOn
instead of mpGridAndLimbOn. Make sure the A in And is capitalized.

Setting gsnPolarLabelFontHeightF = 0.0 just worked for me in a recent
script of mine. If that continues to not work please respond to ncl-talk
with the version of NCL that you are using..
Good luck,
Adam
