Pandas DataFrame plot 绘制饼状图和柱状图

import pandas as pd
import numpy as np

df = pd.DataFrame(np.random.randint(100,size=(3,1)),columns=['num'])
df


# 饼图
# 显示的小数位数 autopct='%.3f%%'
df.plot(kind="pie",subplots=True,autopct='%.3f%%')


# 柱状图
df.plot(kind="bar")

# 选取前半部分，主要看一下 kind ，即可以绘制的图表类型
help(df.plot)
