Example 1
import numpy as np import matplotlib.pyplot as plt mu = 100 # mean of distribution sigma = 20 # standard deviation of distribution x = mu + sigma * np.random.randn(2000) plt.hist(x, bins=10 , color='m' ,) # p1 : normal = True # p2 : ignore normal = True plt.show()
P1
P2
Example 2 :
import numpy as np import matplotlib.pyplot as plt x = np.random.randn(1000) + 2 y = np.random.rand(1000) + 3 plt.hist2d(x,y ,bins=400) plt.show()
