Re: pdfxy

It doesn't look like your x variable has a max value of 60 to me:

  xMIN : 0.4511555433273315
  xMAX : 13.29794788360596

So if you set your nbinx and your binx_max accordingly, then you should get
1.0 spaced bin integers. Have you also tried switching opt@binx_nice to
false? I find this tends to work better when I am specifying my own bins.
