我想在直方图中添加密度图.我对pdf函数有所了解,但我感到困惑,其他类似的问题也无济于事.

from scipy.stats import * 
from numpy import*
from matplotlib.pyplot import*
from random import*

nums = []
N = 100
for i in range(N):
    a = randint(0,9)
    nums.append(a)

bars= [0,1,2,3,4,5,6,7,8,9]
alpha, loc, beta=5, 100, 22

hist(nums,normed= True,bins = bars)


show()

我正在寻找这样的东西
