objectif

Visualiser les relations paires entre colonnes numériques.

code minimal

import seaborn as sns
import pandas as pd, numpy as np
df = pd.DataFrame(np.random.default_rng(0).normal(size=(50,3)), columns=list("abc"))
g = sns.pairplot(df)
print(hasattr(g, "fig"))

utilisation

import seaborn as sns, pandas as pd, numpy as np
df = pd.DataFrame(np.random.default_rng(1).normal(size=(20,2)), columns=["x","y"])
g = sns.pairplot(df, corner=True)
print(hasattr(g, "axes"))

variante(s) utile(s)

import seaborn as sns, pandas as pd, numpy as np
df = pd.DataFrame({"x":[1,2,3], "y":[3,2,1], "cls":[0,1,0]})
g = sns.pairplot(df, hue="cls")
print(hasattr(g, "fig"))
