Thanks Okay trying to understand the data being returned. I have
counts, bins = np.histogram(RedEllipticalMasses['Z_1'],bins=80) If I print lengths I get RedEllipticalMasses is 2514 bins = 81 and counts is 5 ( It is 5 Arrays each of length 80) Okay I can get centers with centers = 0.5 * (bins[1:] + bins[:-1] As you advised But unclear how I would get their heights and why counts has 5 arrays ? -- Sent from: http://numpy-discussion.10968.n7.nabble.com/ _______________________________________________ NumPy-Discussion mailing list NumPy-Discussion@python.org https://mail.python.org/mailman/listinfo/numpy-discussion
