利用Python进行数据分析_Pandas_绘图和可视化_Pandas

线形图

DataFrame.plot()

import pandas as pd
from pandas import DataFrame,Series

df = DataFrame([12,22,53,14,25,36,27,58,69,10],columns = ['A'],index = np.arange(0,100,10))
df.plot()

执行结果：

 

import pandas as pd
import numpy as np
from pandas import DataFrame,Series
df = DataFrame(np.random.randn(4,2),columns = ['A','B'],index = np.arange(0,100,25))# 二维数组中4行2列，index 需要4个，100/25=4，x轴范围0~100
df.plot()

执行结果：

Series.plot()

from pandas import Series,DataFrame
s = Series([3,2,5,7,6,9,0,1,4,8],index=['a','b','c','d','e','f','g', 'h','i','j'])
s.plot()

执行结果：

 

 

from pandas import Series,DataFrame
df = DataFrame([[3,2,5,7,3],[0,1,4,8,3],[3,2,4,8,3],
[6,9,4,8,3]],columns =['A','B','C','D','E'],index=['a','b','c','d'])
df.plot(kind='bar')

执行结果：
