Elegant way to change legend's title size in seaborn plot?

Question

I have created a seaborn pairplot and I want to change the size of the legend's title. I have done that with:

matrix = sns.pairplot(...)
lg = plt.gcf().legend(title='something')
lg.get_title().set_fontsize(30)

Is there a more elegant way to do this?

I know that matplotlib -used by seaborn- does not have a related property as discussed here: https://github.com/matplotlib/matplotlib/issues/8699

Answer 1

Note that from matplotlib 3.0 on , you will be able to change the legend title font-size via

ax.legend(..., title_fontsize=16)

or

plt.rcParams['title_fontsize'] = 16

Until then,

legend = ax.legend(...)
legend.get_title().set_fontsize(16)

is indeed the appropriate way to set the legend title.

plt.title('something', fontsize=16)
