除了plot，经常会用到还有scatter，这个会显示散点图，首先给大家说一下在 pandas 中有多少种方法 bar hist box kde area scatter hexbin

# 随机生成1000个数据df = pd.Series(np.random.randn(1000),index=np.arange(1000),name='d')df.plot()

df = pd.DataFrame(np.random.randn(1000,4), index=np.arange(1000), columns=list("ABCD"))df = df.cumsum()df.plot()plt.show()

In [7]:
df['A'].plot.box()

In [9]:
df.plot.area(stacked=False)
Out[9]:

ax = df.plot.area(y='B',stacked=False)
In [11]:
ax = df.plot.hexbin(x='A', y='B', gridsize=20)
