注释FacetGrid点图

Question

我如何在col1的值“ A”或“ B”的文本旁边，在“ E”上绘制的点旁边注释一个默认的FacetGrid点图。

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

# Data
a = list("ABC") * 4
c = list("DE") * 6
score = np.random.randint(-5, 5, 12)
df = pd.DataFrame({"col1": a, "col2": c, "score": score})
print(df)

   col1 col2  score
0     A    D      4
1     B    E      2
2     C    D     -2
3     A    E     -3
4     B    D      4
5     C    E     -3
6     A    D      2
7     B    E      2
8     C    D     -5
9     A    E      1
10    B    D     -1
11    C    E     -3

g = sns.FacetGrid(data=df, hue="col1", height=5)
g.map(sns.pointplot, "col2", "score", **dict(order=["D", "E"]));

所需的结果带有标签A，B和C：
