如何在JavaFx图表中仅从所选系列中删除符号标记？

import javafx.application.Application;
import javafx.scene.Scene;
import javafx.scene.chart.LineChart;
import javafx.scene.chart.NumberAxis;
import javafx.scene.chart.XYChart;
import javafx.stage.Stage;

public class ChartExample extends Application {

    @Override
    public void start(Stage stage) {
        // 创建图表轴
        final NumberAxis xAxis = new NumberAxis();
        final NumberAxis yAxis = new NumberAxis();
        xAxis.setLabel("X");
        yAxis.setLabel("Y");

        // 创建图表
        final LineChart<Number, Number> lineChart = new LineChart<>(xAxis, yAxis);
        lineChart.setTitle("Chart Example");

        // 创建系列
        XYChart.Series<Number, Number> series1 = new XYChart.Series<>();
        series1.setName("Series 1");
        series1.getData().add(new XYChart.Data<>(1, 2));
        series1.getData().add(new XYChart.Data<>(2, 4));
        series1.getData().add(new XYChart.Data<>(3, 6));

        XYChart.Series<Number, Number> series2 = new XYChart.Series<>();
        series2.setName("Series 2");
        series2.getData().add(new XYChart.Data<>(1, 3));
        series2.getData().add(new XYChart.Data<>(2, 5));
        series2.getData().add(new XYChart.Data<>(3, 7));

        // 将系列添加到图表中
        lineChart.getData().add(series1);
        lineChart.getData().add(series2);

        // 获取所选系列的引用
        XYChart.Series<Number, Number> selectedSeries = series1;

        // 获取系列节点
        Node seriesNode = selectedSeries.getNode();

        // 获取节点的样式类列表
        ObservableList<String> styleClass = seriesNode.getStyleClass();

        // 从样式类列表中移除符号标记的样式类
        styleClass.remove("default-color");
        styleClass.remove("chart-line-symbol");

        // 更新系列节点的样式类列表
        seriesNode.setStyleClass(styleClass);

        // 创建场景并显示图表
        Scene scene = new Scene(lineChart, 800, 600);
        stage.setScene(scene);
        stage.show();
    }

    public static void main(String[] args) {
        launch(args);
    }
}
