[ncl-talk] how to plot a reference arrow legend (such as 4m/s) by using wmvect and wmvlbl function？

[吴冰雪]

Dear All,    The example I have found in the NCL website（as following shown） by using the wmvect and wmvlbl function，the  reference arrow legend is special（like 0.35E+2and the length of the reference arrow is constant by using wmvlbl function ）,which isn’t what I want,.
    I just wonder if any way the reference arrow legend it could be the same look  like use  res at vcRefMagnitudeF and res at vcRefLengthF.
(this is not what I want)(this is what I want)
