Hi Ruby,
I still do not fully understand your question but what I do in such cases is to construct a very simple array and test the functions.
The help of numpy.histogram2d or numpy.histogramdd (for more than two dims) might help here.
So I guess, basically you want to ignore the x,y positions and just look at the combined distribution of the Z values?
In this case, you would just need the numpy.histogram (the 1d version).
Note that the histogram returns the numbers and the bin-borders.
