<div><br></div><div>If all you care about is the font, you can also use the 'stixgeneral' font family, which is actually the font that matplotlib uses internally to display mathtext. You can change the font globally by updating your matplotlibrc or changing your matplotlib configuration at the top of your script.</div>
