Re: [Numpy-discussion] histogram help

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. bests Samuel On 30.01.2012, at 20:27, Ruby Stevenson wrote:

Sorry, I realize I didn't describe the problem completely clear or correct.

the (x,y) in this case is just many co-ordinates, and each coordinate has a list of values (Z value) associated with it. The bins are allocated for the Z.

I hope this clarify things a little. Thanks again.

hi, all

I am trying to figure out how to do histogram with numpy

I have a three-dimension array A[x,y,z], another array (bins) has been allocated along Z dimension, z'

how can I get the histogram of H[ x, y, z' ]?

thanks for your help.
