【问题描述】：

如果我有一个已知分位数的数据框，我可以让 Seaborn 箱线图显示每个百分位数上的小菱形吗？

test = pd.DataFrame(
    {
        "id": ["A", "A", "A", "B", "B", "B", "C", "C", "C"],
        "q": [0.16, 0.5, 0.84, 0.16, 0.5, 0.84, 0.16, 0.5, 0.84],
        "value": [0.2, 0.56, 0.84, 0.14, np.nan, 0.78, 0.125, 0.4, 0.62],
    }
)

display(test)
sns.boxplot(data=test, x="value", y="id")

也许这对你有帮助：

import seaborn as sns
import numpy as np
import pandas as pd
import matplotlib.pyplot as plt


test = pd.DataFrame(
    {
        "id": ["A", "A", "A", "B", "B", "B", "C", "C", "C"],
        "q": [0.16, 0.5, 0.84, 0.16, 0.5, 0.84, 0.16, 0.5, 0.84],
        "value": [0.2, 0.56, 0.84, 0.14, np.nan, 0.78, 0.125, 0.4, 0.62],
    }
)

display(test)
g = sns.boxplot(data=test, x="value", y="id")

    
for index, row in test.iterrows():
    if(row['id']=='A'):
        g.plot((row['q']), (row['id']), 'o', color='y')
    if(row['id']=='B'):
        g.plot((row['q']), (row['id']), 'o', color='b')        
    if(row['id']=='C'):
        g.plot((row['q']), (row['id']), 'o', color='r')
        
plt.show()
