ChartPanel을 사용하여 JFreeChart의 모양을 어떻게 동적으로 업데이트할 수 있습니까?

import org.jfree.chart.ChartPanel;
import org.jfree.chart.JFreeChart;
import org.jfree.chart.event.ChartChangeEvent;
import org.jfree.chart.event.ChartChangeListener;
import org.jfree.chart.plot.XYPlot;
import org.jfree.chart.renderer.xy.XYLineAndShapeRenderer;

public class AppearanceExample {

    public static void main(String[] args) {
        // Create a JFreeChart and ChartPanel
        JFreeChart chart = ...;
        ChartPanel chartPanel = new ChartPanel(chart);

        // Add a listener to the chart to detect changes to its appearance
        chart.addChangeListener(new ChartChangeListener() {

            @Override
            public void chartChanged(ChartChangeEvent event) {
                XYPlot plot = (XYPlot) chart.getPlot();
                XYLineAndShapeRenderer renderer = (XYLineAndShapeRenderer) plot.getRenderer();

                // Update the renderer's visibility settings
                renderer.setBaseShapesVisible(true);
            }
        });
    }
}
