Ändern von Schriftgrad in python Nebenhandlungen

Habe ich eine phase plot eines bistabilen stabil, mit der nulclines auf die wichtigsten Graphen-und eine Nebenhandlung mit der bewegungsbahnen überlagern. Jedoch, egal was ich versuche, ich kann nicht scheinen, um die x-und y-labels zu erhöhen, in Schriftgröße 20.

Jegliche Hilfe würde sehr geschätzt werden.

Zwar gibt es ähnliche Fragen, die Antworten auf Sprach-Abfragen scheinen nicht zu gelten für dieses spezielle problem.

Nochmals vielen Dank!
