将两个箱图分组绘制两列

Question

import matplotlib.pyplot as plt 
import numpy as np 
import matplotlib as mpl 
import pandas as pd

filepath='E:/PROJECT ON DATA SCIENCE/boxplot/fee.csv';
X=pd.read_csv(filepath_or_buffer=filepath,index_col=0)

X.boxplot(by='stype', column='fee')
X.boxplot(by='pincode', column='fee')

Answer 1

如果您想通过stype和pincode对X分组进行箱线图绘制，则可以使用

X.boxplot(column='fee', by=['stype', 'pincode'])

完整的代码应该是

import matplotlib.pyplot as plt 
import numpy as np 
import matplotlib as mpl 
import pandas as pd

filepath='E:/PROJECT ON DATA SCIENCE/boxplot/fee.csv';
X=pd.read_csv(filepath_or_buffer=filepath,index_col=0)

X.boxplot(column='fee', by=['stype', 'pincode'])
