[ncl-talk] No labels shown on the contour plot overlayed

[Adam Phillips]

Hello,
Assuming you are setting cnLineLabelsOn = True for the correct resource
list, then I am guessing that NCL is having trouble putting labels on the
contours (due to the contour density/shape). There is a whole Applications
page devoted to this issue:
https://www.ncl.ucar.edu/Applications/contourLab.shtml
Specifically, see examples #5 and #6.
Hope that helps!
Adam
