matplotlib histogram: how to display the count over the bar?

Question

With matplotlib\'s hist function, how can one make it display the count for each bin over the bar?

For example,

import matplotlib.pyplot         


        

Answer 1

it seems hist can't do this,you can write some like :

your_bins=20
data=[]
arr=plt.hist(data,bins=your_bins)
for i in range(your_bins):
    plt.text(arr[1][i],arr[0][i],str(arr[0][i]))
