padans 做关联分析时常做的叠加图方法

import matplotlib.pyplot as plt

import tkinter

import numpy as np

import pandas as pd

from pandas import Series,DataFrame

data = {‘a’:[1,2,3],’b’:[2,3,1]}

data.plot(kind = ‘bar’,stacked = ‘True’)

plt.show()

与上述代码等价的写法

data = pd.read_csv(‘test.csv’)

data.plot(kind = ‘bar’,stacked = ‘True’)

plt.show()

其中test.csv中内容如下

a,b

1,3

2,2

3,1
