matplotlib绘制条形图

绘制条形图1

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)

绘制条形图2

from matplotlib import pyplot as plt
from matplotlib import font_manager

my_font = font_manager.FontProperties(fname='C:/windows/fonts/msyhl.ttc')

a = ["猩球崛起3：终极之战", "敦刻尔克", "蜘蛛侠：英雄归来", "战狼2"]
b_16 = [15746, 312, 4497, 319]
b_15 = [12357, 156, 2045, 168]
b_14 = [2358, 399, 2358, 362]

plt.figure(figsize=(20,8),dpi=100)

bar_width = 0.2
x_14 = list(range(len(a)))
x_15 = [i + bar_width for i in x_14]
x_16 = [i + bar_width * 2 for i in x_14]

plt.bar(range(len(a)), b_14, width=bar_width, label="9月14日")
plt.bar(x_15, b_15, width=bar_width, label="9月15日")
plt.bar(x_16, b_16, width=bar_width, label="9月16日")

# 设置图例
plt.legend(prop=my_font)

# 设置x轴的刻度
plt.xticks(x_15, a, fontproperties=my_font)

plt.show()
