Как вывести гистограму в QFrame?

Question

Как сделать так, чтобы построенная гистограма отображалась в QFrame (insert_framehis?

Сейчас создается график и вставляется в insert_frame. Но он не похож на диаграму частот. Под диаграмой частот иммею ввиду следующее: Допустим есть масив ages = [10, 10, 30, 40, 50, 50, 50]. Нужно, что б на диаграме числу 10(по оси Х) отвечало число 2(по оси Y), по аналогии 30-1, 40-1, 50-3. Нужно, что б получилось на подобии єтого.

Привел минимальный воспроизводимый пример.

Я не уверен, что понял, какую диаграмму частот вы хотите нарисовать, но попробуйте так:
