JFreeChart is a free 100% Java chart library created by David Gilbert. JFreeChart makes it easy for developers to display professional quality charts in their applications. This article assumes that you have knowledge in Eclipse RCP .

If you want to use use JFreeChart in Swing have a look at the JFreeChart Tutorial .

Download the JFreeChart distribution (jars) from the website JFreeChart Homepage .

For the required Eclipse download please see Eclipse RCP

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.
