python - Histogram Pyplot y axis scaling -

i'm having trouble scaling y axis histogram frequencies rather counts (which have now). want go 0 - 1 rather 0 - 10000. because it's histogram, can't divide 10,000. suggestions?

this code & graph

from pyplot.hist documentation see hist has argument normed:

normed : boolean, optional
if true, first element of return tuple counts normalized form probability density, i.e., n/(len(x)`dbin), i.e., integral of histogram sum 1. if stacked true, sum of histograms normalized 1. default false

you may use normalized histogram.

if instead want counts sum 1, independend of bin width, can divide histogram sum. 2 step process

hist, bins_ = numpy.historgam(results) freq = hist/np.sum(hist) plt.bar(bins_[:-1], freq)
