Re: Number of bins in pdfx function

Hi Ioannis,

I don't know of a way to directly specify the bin spacing in pdfx. But
if you know the min and max values of your data it should be easy to
work out the number of bins to use to get the spacing you want.

Something along the lines of

nbins = (max - min)/bin_spacing

( just make sure this is an integer number)

You can also specify the bin_min and bin_max you want to use as
attributes to the opt argument. This way you can be sure what these
values are when calculating the pdf and that nbins is an integer.

Hope this helps,
Maria
