[ncl-talk] Symbol of circumference ratio

Wed Dec 21 21:14:01 MST 2016

  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
