[ncl-talk] problem with explicit label strings

[Anne]

Hi again,

I think I found a solution to my problem. I think the key resource that I
forgot to set is  res at lbLabelAutoStride     =    False. Together with
following resources I got the labelling the way I wanted (here an example
in which I set explicit contour levels):

res at lbLabelAutoStride     =    False
res at lbLabelFontHeightF          =  0.025
res at cnLevelSelectionMode = "ExplicitLevels"
res at cnFillColors       =  (/2, 25, 50, 75, -1, -1, 160, 180, 200, 220/)
res at cnLevels           =  (/-0.2, -0.15, -0.1, -0.5, 0, 0.5, 1.0, 1.5, 2.0/)
res at cnExplicitLabelBarLabelsOn = True
res at lbLabelStrings = (/"-0.2", "", "-0.1", "", "0", "", "1.0", "", "2.0",
"2.5"/)

Hope that helps,
Anne
