Estoy tratando de graficar dos arreglos con matplotlib utilizando PyQt5, el problema de nuevo es que al correr el programa y doy click en el boton graficar se cierra. Declare un widget en Qt Designer para poder mostrar la grafica.
Este es el codigo, primero declaro el widget y le doy la orden de graficar los arreglos x y sx que anteriormente son calculados, no se si tenga que declara alguna libreria extra como QWidget o algo asi para que pueda mostrar la grafica de estos 2 arreglos.
