Creating Bar Charts with JFreeChart

Create a new Plugin project "de.vogella.rcp.jfreechart.barchart" using "RCP application with a view" as a template. Add "de.vogella.rcp.jfreechart.libs" as a dependency to project "de.vogella.jfreechart.barchart" and change the coding of the view to the following:

   
package de.vogella.rcp.jfreechart.barchart;

import java.awt.Color;

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.CategoryPlot;
import org.jfree.chart.plot.PlotOrientation;
import org.jfree.data.category.CategoryDataset;
import org.jfree.data.category.DefaultCategoryDataset;
import org.jfree.experimental.chart.swt.ChartComposite;

public class View extends ViewPart {

 private CategoryDataset createDataset() {
  DefaultCategoryDataset dataset = new DefaultCategoryDataset();

  // row keys...
  String series1 = "First";
  String series2 = "Second";

  // column keys...
  String category1 = "Label 1";
  String category2 = "Label 2";
  String category3 = "Label  3";

  dataset.addValue(1.0, series1, category1);
  dataset.addValue(4.0, series1, category2);
  dataset.addValue(3.0, series1, category3);

  dataset.addValue(5.0, series2, category1);
  dataset.addValue(7.0, series2, category2);
  dataset.addValue(6.0, series2, category3);

  return dataset;
 }

 /**
  * Creates a chart.
  *
  * @param dataset
  *            dataset.
  *
  * @return A chart.
  */
 private JFreeChart createChart(CategoryDataset dataset) {

  JFreeChart chart = ChartFactory.createBarChart("Bar Chart", // chart
    // title
    "Labels", // domain axis label
    "Values", // range axis label
    dataset, // data
    PlotOrientation.VERTICAL, // orientation
    true, // include legend
    true, // tooltips?
    false // URLs?
    );

  CategoryPlot plot = (CategoryPlot) chart.getPlot();
  plot.setBackgroundPaint(Color.lightGray);
  plot.setDomainGridlinePaint(Color.white);
  plot.setDomainGridlinesVisible(true);
  plot.setRangeGridlinePaint(Color.white);
  return chart;

 }

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

 public void setFocus() {
 }
}
  
  

Run it and see that it is working.
