JFreeChart SplineRenderer code problem

Question

I tried to write simple JFreeChart SplineRenderer code, but it don't work. Can sameone tell whats wrong with it? Netbeans say that error is in XYPlot plot = new XYPlot(dataset, xax, yax, spline); line. I'm newbie in java programming...
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");
XYSplineRenderer spline = new XYSplineRenderer();
NumberAxis xax = new NumberAxis("x");
NumberAxis yax = new NumberAxis("y");
XYPlot plot = new XYPlot(dataset, xax, yax, spline);
JFreeChart chart = new JFreeChart(plot);
ChartPanel chartPanel = new ChartPanel(chart);
frame.setContentPane(chartPanel);
frame.pack();
frame.setVisible(true);

I have another problem. I want to make graphs without points, but only higher graph is without points, what I should change in code to hide points in both graphs?

XYSeries series1 = new XYSeries("XY graph first");
series1.add (0, 0);

XYSeriesCollection dataset = new XYSeriesCollection();
dataset.addSeries(series1);
dataset.addSeries(series2);
ApplicationFrame frame = new ApplicationFrame("Graph");
NumberAxis xax = new NumberAxis("X axis");
NumberAxis yax = new NumberAxis("Y axis");
XYSplineRenderer spline = new XYSplineRenderer();
spline.setPrecision(10);
XYPlot xyplot = new XYPlot(dataset, xax, yax, spline);
//Design
spline.setSeriesShapesVisible(0, false);
xyplot.setBackgroundPaint( Color.pink );
xyplot.setDomainGridlinePaint( Color.WHITE );
xyplot.setRangeGridlinePaint( Color.WHITE );
JFreeChart chart = new JFreeChart(xyplot);
ChartPanel chartPanel = new ChartPanel(chart);
frame.setContentPane(chartPanel);
frame.pack();
frame.setVisible(true);
