RCP 中调用JFreeChart

RCP 中调用JFreeChart：
1. 

package jfreecharttest; 
import java.awt.Font; 
import org.eclipse.swt.SWT; 
import org.eclipse.swt.widgets.Composite; 
import org.eclipse.ui.part.ViewPart; 
import org.jfree.chart.ChartFactory; 
import org.jfree.chart.JFreeChart; 
import org.jfree.chart.plot.PiePlot; 
import org.jfree.data.general.DefaultPieDataset; 
import org.jfree.data.general.PieDataset; 
import org.jfree.experimental.chart.swt.ChartComposite; 
public class View extends ViewPart 
{
  public static final String ID = "JFreeChartTest.view"; 
  private static PieDataset createDataset()
  {
     DefaultPieDataset dataset = new DefaultPieDataset(); 
     dataset.setValue("One", new Double(43.2)); 
     dataset.setValue("Two", new Double(10.0)); 
     dataset.setValue("Three", new Double(27.5)); 
     dataset.setValue("Four", new Double(17.5)); 
     dataset.setValue("Five", new Double(11.0)); 
     dataset.setValue("Six", new Double(19.4)); 
     return dataset; 
  }
  private static JFreeChart createChart(PieDataset dataset) 
  {
     JFreeChart chart = ChartFactory.createPieChart("Pie Chart Demo 1",
     dataset, true,true, false);
     PiePlot plot = (PiePlot) chart.getPlot(); 
     plot.setSectionOutlinesVisible(false); 
     plot.setLabelFont(new Font("SansSerif", Font.PLAIN, 12)); 
     plot.setNoDataMessage("No data available"); 
     plot.setCircular(false); 
     plot.setLabelGap(0.02); 
     return chart; 
  }

  public void createPartControl(Composite parent)
  {
     JFreeChart chart = createChart(createDataset()); 
     final ChartComposite frame = new ChartComposite(parent, SWT.NONE,58 chart, true); 
  }
  public void setFocus() {}
}

2. 在Swing中调用JFreeChart, JFreeChart的API中也有相关的JFrame和JPanel.
