Hi Steven, Try this:
import numpy as np import numpy.random import matplotlib as mpl import matplotlib.pyplot as plt x = np.random.randn(1000) h, binedg = np.histogram(x, 10) wid = binedg[1:] - binedg[:-1] plt.bar(binedg[:-1], h/float(x.size), width=wid) On Nov 30, 2011, at 10:25 AM, Steven Boada wrote: > Hi Users, > > I'm looking to make a histogram that is normalized by the total number > of items shown in the histogram.

Splunk takes this data and makes sense of it. IT sense.
