获得箱内积分

Question

我正在用matplotlib创建boxplot。我如何获得盒子里的积分？

import matplotlib.pyplot as plt 

data = [2,4,5,62,57,3,8,3,96,2,34,43] 

box=plt.boxplot(data) 

Answer 1

盒子内的点是位于所述四分位范围内的值。第一和第三四分可以np.quartile进行计算，一旦你知道这些值，您可以有条件地品尝你的数据数组：

import matplotlib.pyplot as plt 
import numpy as np 

data = np.array([2,4,5,62,57,3,8,3,96,2,34,43]) 

box=plt.boxplot(data) 

# Get all the data between the 1st and 3rd quartile 
data_iqr = data[ (data > np.percentile(data, 25)) & (data < np.percentile(data, 75)) ] 

# Visual confirmation: 
plt.scatter(np.ones_like(data_iqr), data_iqr, marker='o', label='IQR') 
plt.scatter(np.ones_like(data),  data,  marker='x', label='all') 
plt.legend(frameon=False, loc='best')
