Таки не могу найти ошибку. Вот, вставил переделанный кусок своего кода в тот пример, в MyStaticMplCanvas. Весь код у меня на Python3, тут код на втором. Текст ошибки:
RuntimeError: super-class __init__() of type MyStaticMplCanvas was never called
хотя __init__ суперкласса я вроде вызвал.

Александр: Спасибо, как раз недавно его увидел, вроде разобрался. Сейчас как раз переписываю код, надеюсь получится. Как я говорил, я новичок в программировании, занимаюсь немногим больше месяца (не считая нескольких небольших попыток начать), а тут немалая задача свалилась, по причине недостатка опыта приходится иногда долго ломать голову над очевидными другим мелочами.
