[ncl-talk] Legend in panel plot

[jagan TNAU]

Hello Mary,

Thanks for the input. I was able to create plot with explicit values with
equivalent description using "Explicitlevels" and "Boxcentres" for single
plots. However I am unable to create single lablelbar for the PANEL plots.
Is there any additional resources I need to add for doing the same.
Attached script produces label bar for all the plots as seen in the
attached chart. I want a common label bar for all the panel plots
