添加python图，以下代码

import matplotlib.pyplot as plt

import numpy as np

index = np.arange(dataset.shape[0])

p1 =plt.bar(index,dataset["MC_fas"], width=0.3 , color='lightgreen')

p2 =plt.bar(index,dataset["SC_fas"], width=0.3 , color='limegreen')

plt.xticks(index,dataset["product"], rotation = 45)

bar_width = 0.3

p3 =plt.bar(index +  bar_width, dataset["MC_simul_d"], width=0.3 , color='deepskyblue')

p4 =plt.bar(index +  bar_width, dataset["SC_simul_d"], width=0.3 , color='dodgerblue')

plt.legend(["MC_fas","SC_fas","MC_simul","SC_simul"],loc=1)

plt.title('MC SC ')

plt.show()
