绘制竖着的条形图

• 代码如下：

from matplotlib import pyplot as plt
from matplotlib import font_manager

my_font = font_manager.FontProperties(fname='C:\Windows\Fonts\STSONG.TTF')

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]

##图片大小
plt.figure(figsize=(15,6), dpi=80)

##绘图--竖图
plt.bar(range(len(a)), b, width=0.3)#竖图-width设置线条宽度
##x轴坐标
plt.xticks(range(len(a)), a, fontproperties=my_font, rotation=90)

#网格
plt.grid(alpha=0.3)

plt.show()

• 结果如图所示：

绘制横着的条形图

• 代码如下：

from matplotlib import pyplot as plt
from matplotlib import font_manager

my_font = font_manager.FontProperties(fname='C:\Windows\Fonts\STSONG.TTF')

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]

##图片大小
plt.figure(figsize=(15,6), dpi=80)

##绘图--横图
plt.barh(range(len(a)), b, height=0.4, color="orange")#height设置线条宽度
##y轴坐标
plt.yticks(range(len(a)), a, fontproperties=my_font)

#网格
plt.grid(alpha=0.3)

plt.show()

• 结果如图所示：
