seaborn histplot modify legend

import seaborn as sns

df_dn = pd.DataFrame({'ktau': np.random.randn(4000).cumsum(),
                      'statind': np.repeat([*'abcd'], 1000)})

legend.remove()
ax1.legend(handles, ['dep-', 'ind-', 'ind+', 'dep+'], title='Stat.ind.')

sns histplot change legend labels

import seaborn as sns

# load the tips dataset
tips = sns.load_dataset("tips")
# plot
g = sns.lmplot(x="total_bill", y="tip", hue="smoker", data=tips, markers=["o", "x"], facet_kws={'legend_out': True})
# title
new_title = 'My title'
g._legend.set_title(new_title)
# replace labels
new_labels = ['label 1', 'label 2']
for t, l in zip(g._legend.texts, new_labels):
    t.set_text(l)
