How can I draw this graph in Swing?

How can I draw such a graph using Swing? I have used a JFreeChart library, but I don't know how can I draw such a line graph using that library?

graph

import org.jfree.chart.*;
import org.jfree.chart.plot.PlotOrientation;
import org.jfree.data.xy.*;

public class DrawGraph{

public void drawGraph(int[][] drawPoints) {
  XYSeries series = new XYSeries("Average Weight");
  for(int i=0;i<drawPoints.length;i++){
    for(int j=0;j<=1;j+=2){
        if(drawPoints[i][j]!=0){
            series.add(bla...bla...bla...);
        }
    }
  }

  XYDataset xyDataset = new XYSeriesCollection(series);
  JFreeChart chart = ChartFactory.createXYLineChart
  ("XYLine Chart using JFreeChart", "Age", "Weight",
 xyDataset, PlotOrientation.VERTICAL, true, true, false);
  ChartFrame frame1=new ChartFrame("XYLine Chart",chart);
  frame1.setVisible(true);
  frame1.setSize(300,300);
  }

}

I have drawn graph using this but isn't working...

It looks like you're having trouble constructing a dataset. You can use a method like that shown below with either ChartFactory.createXYAreaChart() or ChartFactory.createXYLineChart().

private static XYDataset createDataset() {
    XYSeriesCollection result = new XYSeriesCollection();
    XYSeries series = new XYSeries("Test");
    series.add(0, 2);
    // more points here
    series.add(10, 10);
    result.addSeries(series);
    return result;
}

See also these examples.

As an aside, it's not clear what's important in you picture, and I can't make sense of the unordered axis at the top. In my opinion, the better question is not How do I make this graph? but rather How can I best display this data?

Use JUNG instead. Its easy and written in java.
