[ncl-talk] Panel plot tickmarks and labelbars

[Adam Phillips]

Hi Giorgio,
The only issue that I see in your script is that you are setting the label
bar label font size to an extremely large value:
res1 at lbLabelFontHeightF = 2.
res2 at lbLabelFontHeightF = 2.
res3 at lbLabelFontHeightF = 2.

Try setting each of those to something in the range of 0.020 and see if
your labels show up. If they don't, let ncl-talk know.
