Stefan,

I'm not sure:

the docs say the input has to be:
sample : array_like
    Data to histogram passed as a sequence of D arrays of length N, or
    as an (N,D) array

i have an (N,M,D) array and not sure how to get it to conform to input
required, mainly because I don't understand what it's asking.
