?? 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

Hi,

I have seen three inputs only :

function pdfx (
                x        : numeric,
                nbin [1] : integer,
                opt  [1] : logical
        )
the others are in the return value.

Hi,

Those resources in the warning messages are inputs to the pdfx() functions, not to the graphics functions.  See:

http://ncl.ucar.edu/Document/Functions/Contributed/pdfx.shtml

Hope that helps...

Dear,

I would like to reduce the size of the bins for a PDF plot, I got these errors:

==========

warning:bin_bound_min is not a valid resource in pdf_climate_xy at this time

here is the script:

ap= pdfx(ucH,20,True)
bp= pdfx(ucR,20,True)
cp= pdfx(bcH,20,True)
dp= pdfx(bcR,20,True)

nVar    = 4
nBin    = ap at nbins
;plot    = new ( nVar, "graphic")
xx      = new ( (/nVar, nBin/), typeof(ap))
  xx(0,:) = ap at bin_center
  xx(1,:) = bp at bin_center
  xx(2,:) = cp at bin_center
