Seaborn does not show legend with %matplotlib notebook

Question

When I use %matplotlib notebook, the legend is not displayed.

%matplotlib notebook
...
fg = seaborn.FacetGrid(data=df, hue='Scenario', hue_order=df.Scenario.unique().tolist(), aspect=1.61)
fg.map(plt.scatter, 'Yaw', 'posNoseEye').add_legend()

While when I use %matplotlib inline, the legend is correctly shown.

%matplotlib inline
...
fg = seaborn.FacetGrid(data=df, hue='Scenario', hue_order=df.Scenario.unique().tolist(), aspect=1.61)
fg.map(plt.scatter, 'Yaw', 'posNoseEye').add_legend()

How to manage it in %matplotlib notebook ? Thanks

As I can't put image in the comment, I tried the answer below and it still does not work. I have the last version of matplotlib and seaborn.

Answer 1

The figure does not have any space for the legend. There are several ways to overcome this, as shown in this answer.

An option is to manually create some space for the legend, e.g.

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

df = pd.DataFrame(np.random.rand(20,2), columns=['Yaw', 'posNoseEye'])
df["Scenario"] = np.random.choice(["Scenario A","Scenario B"], size=20)

fg = sns.FacetGrid(data=df, hue='Scenario', hue_order=df.Scenario.unique().tolist(), aspect=1.61)
fg.map(plt.scatter, 'Yaw', 'posNoseEye')

fg.fig.legend()

fg.fig.subplots_adjust(right=0.7)
plt.show()
