[ncl-talk] Legend in panel plot

[Mary Haley]

Hi,

The issue is that by default, the labels on the labelbar are drawn in
"InteriorEdges" mode, and you want to use "BoxCenters" mode.

Please see the second frame in example lb_14.ncl at:

http://www.ncl.ucar.edu/Applications/labelbar.shtml#ex14

I think all you need is:

  res at lbLabelAlignment = "BoxCenters"
  res at lbLabelStrings      =
(/"Arid","Semi-arid","Mediterranean","Semi-humid","Humid","Very
Humid","Extremely Humid"/)

You may also want to look at the "classification data" examples page:

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

and in particular, example "permafrost_1.ncl", which has an explicitly
labeled labelbar.
