python数据分析matplotlib之条形图

知识要点:
　　bar: 绘制竖状条形图   width: 参数配置条形大小

　　barh: 绘制横状条形图    height: 参数配置条形大小

绘制竖状条形图code: 

# coding=utf-8
from matplotlib import pyplot as plt
from matplotlib import font_manager
my_font = font_manager.FontProperties(fname=r"C:\Windows\Fonts\simsun.ttc", size=18)

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]

#设置图形大小
plt.figure(figsize=(20, 15), dpi=80)
#bar: 绘制条形图 width条形宽度
plt.bar(range(len(a)), b, width=0.3)
#设置字符串到x轴
plt.xticks(range(len(a)), a, fontproperties=my_font, rotation=90)
# 绘制的图保存到本地
plt.savefig("./movie.png")

plt.show()

绘制横状条形图code:

#绘制横着的条形图
from matplotlib import pyplot as plt
from matplotlib import font_manager
my_font = font_manager.FontProperties(fname="/System/Library/Fonts/Hiragino Sans GB.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]

#设置图形大小
plt.figure(figsize=(20, 8), dpi=80)
#barh: 绘制条形图  在绘制横着的条形图时, 条形的大小用 height参数表示
plt.barh(range(len(a)), b, height=0.3, color="orange")
#设置字符串到x轴
plt.yticks(range(len(a)), a, fontproperties=my_font)
# 添加网格 alpha: 透明度
plt.grid(alpha=0.3)
# plt.savefig("./movie.png")

plt.show()
