Zmiana ciągła w BufferedImage

W programie chodzi o to, żeby wyświetlał odpowiedni wykres w zależności od ustawienia JScrollBarów. Moje główne pytanie brzmi jak zrobić, żeby ten właśnie wykres zmieniał się na bieżąco ze zmianą wartości dla JScroolBarów? Poza tym nie potrzebuję oznaczeń na osiach, stąd drugie pytanie jak je usunąć?
W programie panuje trochę chaosu za co z góry przepraszam.

zrób coś w stylu :

public class TEMP extends JFrame {

    JScrollBar scrBar = new JScrollBar();
    JPanel pan1 = new JPanel();
    JPanel pan2 = new Pan1(100);
    JButton b = new JButton();

    public TEMP() throws HeadlessException {

        setLayout(new GridLayout(0, 1));
        add(pan1);
        add(pan2);
        pan1.add(scrBar);

        scrBar.addAdjustmentListener(new AdjustmentListener() {

            @Override
            public void adjustmentValueChanged(AdjustmentEvent e) {
                ((Pan1) pan2).setScrPosition(e.getValue());
                pan2.repaint();
                pan2.revalidate();

            }
        });
    }

    public static void main(String[] args) {
        SwingUtilities.invokeLater(new Runnable() {

            @Override
            public void run() {
                JFrame fr = new TEMP();
                fr.setSize(500, 500);
                fr.setVisible(true);
                fr.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

            }
        });
    }
}

class Pan1 extends JPanel {

    int scrPosition = 50;

    public void setScrPosition(int scrPosition) {
        this.scrPosition = scrPosition;
    }

    public Pan1(int pos) {
        this.scrPosition = pos;
    }

    @Override
    protected void paintComponent(Graphics g) {
        super.paintComponent(g);
        g.setColor(Color.red);
        g.drawLine(0, 0, scrPosition, this.getHeight());

    }
}
 

Trochę zmieniona wersja, wzorowana na podpowiedzi remigio. Tylko tnie się bardzo. Może ktoś wie dlaczego?
Poza tym co zrobić, żeby poprzedni wykres znikał?

1. Musisz czyścić kolekcję, przed nowym wykresem dodaj

series.clear();

2. Po co Ci WindowsListener i mnóstwo pustych metod? Wywal wszystkie i dopisz do konstruktora klasy Pro jeden wiersz

setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

3. Koniecznie musi się zmieniać wykres podczas przesuwania suwaka? Może starczy by zmienił się po puszczeniu suwaka?

        @Override
        public void adjustmentValueChanged(AdjustmentEvent e) {
                if(((JScrollBar)e.getSource()).getValueIsAdjusting())
                {
                    return;
                }
                ...

Robicie wiele niepotrzebnych rzeczy w metodzie paintComponent(), co strasznie zamula program.
Lista zmian:
-nowe pole w klasie Pro

    XYSeries series = new XYSeries("XYGraph");
    XYSeriesCollection dataset = new XYSeriesCollection();
    JLabel lblChart = new JLabel();

-zmiana w konstruktorze

        autorItem.addActionListener(this);

-zmiana metody paintComponent()
