How to Move the Legend in Seaborn\'s Factorplot?

Customizing Seaborn Legend Placement

In seaborn's factorplot(kind="bar"), the legend's location is often not ideal, especially when the plot's elements are crowded. This article explores how to move the legend to a more suitable position, such as the top-left corner.

One approach is to prevent seaborn from generating the legend by setting legend=False. Subsequently, you can manually create the legend using matplotlib:

<code class="python">import seaborn as sns
import matplotlib.pyplot as plt

sns.set(style="whitegrid")

titanic = sns.load_dataset("titanic")

g = sns.factorplot("class", "survived", "sex",
                   data=titanic, kind="bar",
                   size=6, palette="muted",
                   legend=False)
g.despine(left=True)
plt.legend(loc='upper left')
g.set_ylabels("survival probability")</code>

Note: To interact with the FacetGrid's axes from matplotlib, use fig.get_axes()[0]. For instance:

<code class="python">g.fig.get_axes()[0].legend(loc='lower left')</code>
