[ncl-talk] How to have a plot with different panel label bar

[Adam Phillips]

Hi Anahita,
Change this:
res at lbLabelBarOn        = False           ; turn off individual cb's
to this:
res at lbLabelBarOn        = True          ; turn off individual cb's

and change this:
 resP at gsnPanelLabelBar = True
to this:
 resP at gsnPanelLabelBar = False

If you need titles for your labelbars you can use the same resources in
resP but apply them to res. Thus:
res at lbTitleString    = "%"                ; title string
res at lbTitlePosition  = "Right"              ; title position
res at lbTitleFontHeightF= .02                ; make title smaller
res at lbTitleDirection = "Across"             ; title direction

Hope that helps. If you have any further queries please respond to ncl-talk.
