[Numpy-discussion] np.histogram on arrays.

Hi all.

Sorry if this question has already been asked. I've searched the archive, but 
could not find anything related, so here is my question.

I'm using np.histogram on a 4000x4000 array, each with 200 bins. I do that on 
both dimensions, meaning I compute 8000 histograms. It takes around 5 seconds 
(which is of course quite fast).

I was wondering why np.histogram does not accept an axis parameter so that it 
could work directly on the array without me having to write a loop.

Or maybe did I miss some parameters using np.histogram.

Thanks.

Éric.
