Witam wszystkich, to mój pierwszy post więc mam nadzieje że wstawiam wszystko w odpowiednie miejsce.
Piszę z prośbą o pomoc. Piszę aktualnie swój pierwszy projekt w Pythonie używając frameworka PyQ5t i biblioteki matplotlib, ale problem dotyczy samego działania PyQt5. Apka ma proste działanie, odczytywanie i pobieranie danych z netu w formacie JSON i CSV i na ich podstawie wyświetlanie wykresów itp. Aktualnie mam napisane pierwsze okno, w którym wybiera się co chce się wyświetlić (aktualnie tylko jedna opcja dotycząca wyświetlania w postaci wykresu danych pobranych z GitHuba). Wyboru dokonuje się przez naciśnięcie przycisku. Po naciśnięciu przycisku okno się odświeża i wyświetlają się kolejne przyciski, dzięki którym użytkownik ma wybierać jaki język programowania go interesuje. Wszystko działało w porządku do momentu gdy do drugiego okna (tego z wyborem języków programowania) dodałem metody obsługujące wciskanie przycisków. Cała apka się wysypuje i samoistnie wyświetla jeden wykres. Wstawiam kod poniżej, z góry dziękuje za pomoc ;)
