import matplotlib.pyplot as plt
import numpy as np

from pylab import mpl
mpl.rcParams[‘font.sans-serif‘] = [‘STZhongsong‘]    # 指定默认字体：解决plot不能显示中文问题
mpl.rcParams[‘axes.unicode_minus‘] = False

x=["孙悟空","唐僧","猪八戒","沙悟净"]

y=[4,1,3,2]

plt.bar(x,y,width=0.5,align="center",label="战力值",color="red")

plt.title("师徒战力排行榜",loc="center")

for a,b in zip(x,y):
 plt.text(a,b,b,ha=‘center‘,va="bottom",fontsize=12)
