Remove seaborn lineplot legend title

Question

I would like to remove the title from my seaborn lineplot legend. I tried using this answer to no avail:

import matplotlib.pyplot as plt
import seaborn as sn         


        

Answer 1

Important: This answer is about the case when a hue is used that appears as a legend title. In all other cases, the question itself already contains the usual way to get rid of a title.

Indeed, seaborn is misusing a legend label as a (subgroup-)title. Hence the idea can be to either remove this label, or replace it with custom text.

Replacing with custom text:

legend = ax.legend()
legend.texts[0].set_text("Whatever else")

Removing the label:

handles, labels = ax.get_legend_handles_labels()
ax.legend(handles=handles[1:], labels=labels[1:])

After having removed the label you may of course still set another (real) title:

handles, labels = ax.get_legend_handles_labels()
ax.legend(handles=handles[1:], labels=labels[1:], title="Whatever else")
