[ncl-talk] question about windrose circles

I have looked at the function code.

%> less  $NCARG_ROOT/lib/ncarg/nclscripts/csm/wind_rose.ncl

===
lines:

  dirFrMaxNumCircles = toint(dirFrMax/circFr +1.)
  dirFrMaxNum        = circFr*dirFrMaxNumCircles   ; number of circles
===

The following is untested ....

Perhaps making a copy of 'wind_rose.ncl' a

%> cp $NCARG_ROOT/lib/ncarg/nclscripts/csm/wind_rose.ncl
wind_rose.liu_chang.ncl

Then, make a modification to wind_rose.liu_chang.ncl such as

  dirFrMaxNumCircles = toint(dirFrMax/circFr +1.)
;  dirFrMaxNum        = circFr*dirFrMaxNumCircles   ; number of circles <
Comment
  dirFrMaxNum        = 3


then use the new code via

load "./wind_rose.liu_chang.ncl"

Again ... this is untested.

Good luck
