Something like this should work:


res at tmXBLabel = "~F33~p~F~/2"


Explanation:
~ is the symbol that tells NCL to change the font
F33 is the font table corresponding to greek letters (http://www.ncl.ucar.edu/Document/Graphics/font_tables.shtml)
p corresponds to pi into the aforementioned font table
~F switch to the normal font again


Cheers

  Dear NCL:

                     I need to display the symbol of circumference ratio (Pi) in the axis of a plot, say
 
                         res at tmXBLabels                 = (/" Pi/2"/)

 
                     how can I do that?

   Best
   Cheung
