I don't know about easy, but here is a start:

normHist, lower_edges = numpy.histogram(Hlist, bins=100, normed=True)
binWidth = lower_edges[-1]/len(lower_edges)
cumHist = normHist.cumsum()*binWidth
pylab.plot(lower_edges+0.5*binWidth, cumHist)

Needs some tweaking, no doubt.

Subject
[Matplotlib-users] Cumulative histogram






I have an array of absolute magnitudes Hlist and would like to
plot a cumulative histogram. Is there an easy way to do this
in matplotlib?

Cheers
