[ncl-talk] Label Bar Label Missing

Tue Apr 11 11:55:59 MDT 2017

Hi Barry,
Thanks for providing an easy-to-run script as that made debugging this much
easier. It turns out that the solution is simply a matter of providing a
units attribute for the data array (liq_equiv_sml) that you are passing to
wrf_contour at line 279.
Thus, append this line:
liq_equiv_sml at units = "mm"    ; needs to be set to something other than ""
above this line:
contour = wrf_contour(a,wks,liq_equiv_sml,res1)

I was able to get your plot to show the label bar title after appending
that line. The reason for all this is that wrf_contour expects a units
attribute to be set, and if it does not get one it internally
sets lbTitleOn = False. (See line 2706 in WRFUserARW.ncl and trace up from
there.) The current WRFUserARW.ncl coding precludes the user from manually
setting the lbTitleString unless there is a units attribute that is set to
something other than an empty string ("").

To answer your question about creating a greater/less than or equal symbol:
Strangely, I could not find that character in the NCL font tables. You
could create them though by drawing a > or < and using function codes to
back up and draw a _.  For example:
subtitle = "a >~H-16~_ 6"

Hope that all helps. If you have any further questions let ncl-talk know.
Adam
