Re: gsn_csm_contour_map

Hi Halil,

Whenever you want to specify the contour levels, you need to set
the cnLevelSelectionMode resource:
http://www.ncl.ucar.edu/Document/Graphics/Resources/cn.shtml#cnLevelSelectionMode

You can see this resource used here:
http://www.ncl.ucar.edu/Applications/color.shtml#ex2

In your case, you will want to do something like this:

   res_at_cnLevelSelectionMode = "ManualLevels"
   res_at_cnMinLevelValF = 1
   res_at_cnMaxLevelValF = 10
   res_at_cnLevelSpacingF = 1

as you have data that starts at 0 and goes up to 10. (Note that that
those settings will create a labelbar with 11 colors. The first color
will be for all areas whose values is less than 1.) If you want, you
could set the following resources as well to put labels in the middle of
your label bar, denoting that the first color corresponds to those areas
equal to 0, the second to areas = 1, and so on:

   res_at_lbLabelStrings = ispan(0,10,1) ; 0, 1, 2, 3, 4,etc
   res_at_lbLabelPosition = "Center" ; label position
   res_at_lbLabelAlignment = "BoxCenters"
