How to normalize a histogram in python?

Question

I\'m trying to plot normed histogram, but instead of getting 1 as maximum value on y axis, I\'m getting different numbers.

For array k=(1,4,3,1)

 import

One way is to get the probabilities on your own, and then plot with plt.bar:

In [91]: from collections import Counter
    ...: c=Counter(k)
    ...: print c
Counter({1: 2, 3: 1, 4: 1})

In [92]: plt.bar(prob.keys(), prob.values())
    ...: plt.show()

result:
