JAVAFX LineChart dynamiczne aktualizowanie danych.

Witam, mam pewien problem z wstawianiem danych do LineCharta, ktory jest zainicjowany w fxml, próbuje do niego wsadzić dane z poziomu kontrolera i ni cholery nic sie nie chce zmieniac, moze to jakis banalny blad wynikający z mojej niewiedzy jednak prosiłbym o podpowiedź.
Ponizej zamieszczam kod kontrolera i fxml
