Hi A.J.,
You are telling NCL to not label the min/max values by setting the
cnHighLabelString/cnLowLabelString resources = "H"/"L"..
According to the documentation here:
http://www.ncl.ucar.edu/Document/Graphics/Resources/cn.shtml#cnHighLabelString
http://www.ncl.ucar.edu/Document/Graphics/Resources/cn.shtml#cnLowLabelString
the defaults are:
res@cnHighLabelString = "H~B~$ZDV$~E~"
res@cnLowLabelString = "L~B~$ZDV$~E~"
(note that I replaced the : with ~ as that is what most people have
their function code set to..)
Try setting the resources as I have it above and see if that works.. If
not, please let ncl-talk know..
