from matplotlib import pyplot as plt
    from matplotlib import font_manager
    
    my_font = font_manager.FontProperties(fname='C:/Windows/Fonts/msyhl.ttc')
    a = ["战狼2", "速度与激情8", "功夫瑜伽", "西游伏妖篇", "变形金刚5：最后的骑士", "摔跤吧！爸爸", "加勒比海盗5：死无对证", "金刚：骷髅岛", "极限特工：终极回归",
         "生化危机6：终章",
         "乘风破浪", "神偷奶爸3", "智取威虎山", "大闹天竺", "金刚狼3：殊死一战", "蜘蛛侠：英雄归来", "悟空传", "银河护卫队2", "情圣", "新木乃伊", ]
    
    b = [56.01, 26.94, 17.53, 16.49, 15.45, 12.96, 11.8, 11.61, 11.28, 11.12, 10.49, 10.3, 8.75, 7.55, 7.32, 6.99, 6.88,
         6.86, 6.58, 6.23]
    
    plt.figure(figsize=(20, 8), dpi=100)
    
    plt.barh(range(len(a)), b, height=0.3)
    
    plt.yticks(range(len(a)), a, fontproperties=my_font)
    
    plt.grid(alpha=0.3)
    
    plt.show()

结果显示：

技术要点：

1.  bar绘制条形图(竖着的)
2.  barh(横着的)
