[ncl-talk] lbLabelStrings not overwriting cnLevels

[Mary Haley]

Hi Victoria,

Sorry about the delay. Most of the NCL team was out for a workshop last
week.

You shouldn't need to set cnExplicitLabelBarLabelsOn at all.

In order to control the labelbar label strings, you should only need
lbLabelStrings.

Did you see example vegland_1.ncl at:

http://www.ncl.ucar.edu/Applications/classification.shtml

See the first frame of this example, which does something similar to what
you want.

If you want every single box labeled, then you may need to set
lbLabelAutoStride to False, because otherwise NCL might try to reduce the
number of labels added to the boxes. You shouldn't  additionally need to
set lbLabelStride to 1, although this doesn't hurt.
