[ncl-talk] labelbar

[Rick Brownrigg]

Hi,

The place in the code where the warning message is issued is guarded by
this conditional:


if(end_labels_on.and.end_labelbar_style.eq.get_enum_value("IncludeMinMaxLabels").and.
\
        (lbstrings(0).eq."".or.lbstrings(nlab-1).eq."")) then

It appears as though at least one of the end-labels is blank. Its not clear
to me why, and I would need your code and datasets in order to track this
down.  (BTW: I a bit puzzled by the narrowing of the label range -- I might
have thought widening it was in order; e.g., -135 - 15. / 0 + 15. ??)
