[ncl-talk] bin size

[Dennis Shea]

?? Did you read the documentation for pdfx? ??

ap= pdfx(ucH,20,True)   ; your code

  opt         = True
  opt at bin_min =  0.0
  opt at bin_max =  20.0
 ;opt at bin_nice= True    ; if activated 'nbin' will be ignored
  nbin        = 20      ; you could increase this
  ap = *pdfx*(ucH, nbin, opt)

These should be deleted.

  res at bin_bound_min           =0
  res at bin_bound_max           =20
  res at bin_spacing             =5

=================================

I think you should look at NCL's
