Change Font Size Of Facet Titles Using Seaborn Facetgrid Heatmap

Note: this is a different question than 'How can I change the font size using seaborn FacetGrid?'. The methods suggested there do not work when using a heatmap inside a facetgrid.

Solution 1:

Thanks @mwaskon, that is the answer - use size= when called set_titles.

That leads to more questions, like

• Can you please change set_titles used fontweight= and fontsize= instead of fontweight= and size=? size= is use elsewhere for the facet height in inches.
• why is sns.plotting_context completely ineffective in this context?
