我正在尝试创建简单的XYSplineRenderer,但是只有在我编写XYDotRenderer a = new XYDotRenderer()时才能使用代码.或XYLineAndShapeRenderer a = new XYLineAndShapeRenderer(); 同一个人可以告诉我做错了吗？我只是编程的初学者.

这是我的代码:

package kubas;

import org.jfree.chart.*;
import org.jfree.chart.axis.*;
import org.jfree.chart.plot.*;
import org.jfree.chart.renderer.xy.XYSplineRenderer;
import org.jfree.data.xy.*;
import org.jfree.ui.ApplicationFrame;

public class spausdink {

    public static void main(String[] args) {

XYSeries series = new XYSeries("XY grafikas");
        series.add(1, 2);
        series.add(2, 4);
        series.add(3, 8);
        series.add(4, 16);
        series.add(5, 32);
        series.add(6, 64);
        series.add(7, 128);
        series.add(8, 256);
        series.add(9, 512);
        series.add(10, 1024);

XYSeriesCollection dataset = new XYSeriesCollection();
        dataset.addSeries(series);



ApplicationFrame frame = new ApplicationFrame("Mano grafikas");


        NumberAxis xax = new NumberAxis("x");
        NumberAxis yax …
