Это мой код. Он имитирует сигнал, который я получаю от осциллографа. Я пытаюсь создать интерфейс, но я новичок в программировании (и английском языке), и у меня возникли некоторые проблемы.

я уже создаю график графика в реальном времени и кнопку, но при нажатии сигнал перестает обновляться, и я просто получаю один и тот же сигнал снова и снова. Мне просто нужно знать, как постоянно обновлять сигнал, пока я нахожусь в цикле, если это возможно.
