[ncl-talk] bin size

[Rick Brownrigg]

Yes you are right, my mistake -- those specific resources are return values
from pdfx().  There are however these input resources that can be attached
to the 3rd parameter (opt) of pdfx():

Setting opt=True will activate use of the options.

   - *v510* - The original *pdfx* has been modified. The new [5.1.1]
   function was created to be more consistent with the *pdfxy*
   <http://ncl.ucar.edu/Document/Functions/Contributed/pdfxy.shtml>
   released with 5.1.1. Setting the *v510* attribute to True will result in
   the original v5.1.0 version being used. [see *Description*]
   - *bin_min* - minimum value for the bin boundary.
   - *bin_max* - maximum value for the bin boundary.
   - *bin_nice* - "nice" bin boundary values and spacing will be
   calculated. If the user has specified *nbin*, it will be ignored and the
   calculated number of bins will be used.

Do any of these get you what you need?   Perhaps someone more knowledgeable
on PDFs can comment here...
