The labelbar examples page is a good place to visit for questions regarding customizing a labelbar.

For the min/max labels, see example lb_10.ncl, and in particular, the "cnLabelBarEndLabelsOn" resource.

For formatting the labels themselves, see lb_7.ncl

Example lb_7.ncl says that you can't format the labels apriori, but this is not exactly true.

If you know what your contour levels are before you create the plot, then you can format
these levels using "sprintf", and set "lbLabelStrings" equal to this.

For example, let's say you are setting the contour levels with:

res@cnLevels = fspan(5.82,24.87,26)

Then you can set the labelbar strings with something like:

res@lbLabelStrings = sprintf ("%5.2f",res@cnLevels)

As a side note: I noticed you have what appears to be "times-roman" as your font.
This indicates you are running an older (6.0 or earlier) version of NCL. We
recommend using the "helvetica" font which looks better for publication.

To get helvetica, you can do one of two things:

  - Upgrade to NCL V6.1.2, in which "helvetica" is the default font.

  - Create a ".hluresfile" that goes in your home directory, and set
     the font there. For more info, see:
