Я пытаюсь поместить интерактивный график matplotlib (тот, который имеет ползунки, кнопки сброса и радиокнопки) в холст tkinter. Мне удалось добавить неинтерактивный граф, но я не могу найти проблемы, когда он становится интерактивным.
Я безуспешно пытался изменить все на использование рисунка matplotlib вместо pyplot.
Поскольку код в настоящее время написан, оба класса работают, но когда строка 59 изменяется с graph = FigureCanvasTkAgg(self.random_graph(),self.graph_tab) на graph = FigureCanvasTkAgg(EllipseSlider(),self.graph_tab) и plt.show() удаляется, код больше не работает.
Любая помощь будет отличной. Код ниже.
