JavaFX折线图我想在线条下面创建曲线和线性颜色

public class LineChartExample extends Application {

    @Override

        // 创建X轴和Y轴
        NumberAxis xAxis = new NumberAxis();
        NumberAxis yAxis = new NumberAxis();

        // 创建折线图
        LineChart<Number, Number> lineChart = new LineChart<>(xAxis, yAxis);

        // 创建曲线路径
        Path curve = new Path();
        curve.getElements().add(new MoveTo(0, 0));
        curve.getElements().add(new CubicCurveTo(50, 100, 150, 50, 200, 100));
        curve.setStroke(Color.BLUE);
        
        // 创建线性颜色
        LinearGradient linearGradient = new LinearGradient(0, 0, 1, 0, true, null);
        linearGradient.getStops().add(new Stop(0, Color.RED));
        linearGradient.getStops().add(new Stop(1, Color.YELLOW));
        curve.setFill(linearGradient);

        // 将曲线添加到折线图上
        lineChart.getData().add(new XYChart.Series<>(null, null, curve));

        // 创建场景并显示
        Scene scene = new Scene(lineChart, 400, 300);
        stage.setScene(scene);
        stage.show();
    }

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