How to Customize Legend Placement in Seaborn\'s Bar Plots?

Customizing Legend Placement in Seaborn's Bar Plots

Seaborn's factorplot is a versatile tool for creating multi-faceted visualizations. However, the default legend placement may not always be ideal. In this guide, we will address the issue of moving the legend to a preferred location, such as the top-left corner.

One approach suggested by a previous user is to disable the built-in legend with legend=False and explicitly create a custom legend using Matplotlib. This method provides more control over the legend's position and appearance.

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

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>

In this example, we disable the seaborn legend and create a Matplotlib legend at the top-left position using the loc keyword argument. You can also specify other positions such as 'lower left', 'center', or 'best'.

Additional Considerations:

• plt.legend() operates on the current axes. If you have multiple axes in your plot, you can use g.fig to access the figure object and get the desired axes.

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

• Consider using the despine() function to remove spines and improve the overall appearance of the plot.

By following these steps, you can customize the legend placement in seaborn's bar plots to meet your specific requirements.
