Python Matplotlib绘制箱型图(箱线图)boxplot的方法详解

import pandas as pd
import matplotlib.pyplot as plt
#读取数据
datafile = u'D:\\pythondata\\learn\\matplotlib.xlsx'
data = pd.read_excel(datafile)
box_1, box_2, box_3, box_4 = data['收入_Jay'], data['收入_JJ'], data['收入_Jolin'], data['收入_Hannah']
plt.figure(figsize=(10,5))#设置画布的尺寸
plt.title('Examples of boxplot',fontsize=20)#标题，并设定字号大小
labels = 'Jay','JJ','Jolin','Hannah'#图例
plt.boxplot([box_1, box_2, box_3, box_4], labels = labels)#grid=False：代表不显示背景中的网格线
# data.boxplot()#画箱型图的另一种方法，参数较少，而且只接受dataframe，不常用
plt.show()#显示图像

labels = 'Jay','JJ','Jolin','Hannah'#图例
#vert=False:水平箱线图；showmeans=True：显示均值
plt.boxplot([box_1, box_2, box_3, box_4], labels = labels, vert=False,showmeans=True )
