[ncl-talk] gsn_contour_shade

Thu Jul 19 13:51:40 MDT 2018

Hi Laura,

I don't know with certainty that this works, but you might try:

*gsnContourLineThicknessesScale* This resource, recognized by any gsn
contour <http://ncl.ucar.edu/Document/Graphics/Interfaces/#Contours>
drawing routine, allows you to set line thickness scale factors for all
contour lines. For example, aq value of 2.0 will make the lines twice as
thick. If this is set to an array that is not large enough to handle all
contour lines, then the default value of 1.0 will be used for the remaining
contour lines.
