Необходимо построить график по нажатии кнопки после ввода данных и подсчета по формулам
Необходимо с подсчетом по формулам, построить график по нажатии кнопки после ввода данных.
График строиться из зависимости W по оси y от q по оси x интервале q=(0,1..1.5).
Также нужно сделать кнопку "обновить", чтобы без выхода из приложения можно было ввести еще раз данные и график (синхронное отображение и исчезновение графика с подсчетом ).
Если программа считает и выводит данные, то прописать зависимость для графика не получается .
Помогите,пожалуйста.Ссылка на файл программы: https://drive.google.com/file/d/1q-yNRaDwGaB9v_EeK3jl0tWWM1aU7GsK/view?usp=sharing. '''
