Re: pdfxy

Hi Julia,

I don't think your idea works:

Variable: pdf2
Type: double
Total Size: 11040 bytes
            1380 values
Number of Dimensions: 2
Dimensions and sizes: [y | 23] x [x | 60]
Coordinates:
            y: [ 1.5..23.5]
            x: [0.5582121461629868..13.1908912807703]
Number Of Attributes: 26
  _FillValue : 9.969209968386869e+36
  nMax : 9925
  nUse : 9925
  nOut : 0
  pcUse : 100
  pcOut : 0
  xMIN : 0.4511555433273315
  xMAX : 13.29794788360596
  binx_center : <ARRAY of 60 elements>
  binx_bounds : <ARRAY of 61 elements>
  binx_bound_min : 0.4511555433273315
  binx_bound_max : 13.29794788360596
  binx_spacing : 0.2141132056713104
  nbinsx : 60
  pcxLoOut : 0
  pcxHiOut : 0
  yMIN : 1
  yMAX : 24
  biny_center : <ARRAY of 23 elements>
  biny_bounds : <ARRAY of 24 elements>
  biny_bound_min : 1
  biny_bound_max : 24
  biny_spacing : 1
  nbinsy : 23
  pcyLoOut : 0
  pcyHiOut : 0
(0)
(0) min=0.0100756 max=5.93451

I'm not sure how pdfxy creates the bins.
