Take a look at the birt project, it owns a charting lib.

hi Mr.Dundar,
I have to work with Pie Chrts using JfreeCharts(for SWT).
But in the RCP Application the Eclipse is not able to create the view.
i have the following jars :
1. jcommon-1.0.16.jar
2. jfreechart-1.0.13-experimental.jar
3. jfreechart-1.0.13-swt.jar
4. jfreechart-1.0.13.jar
5. jfreechart-1.0.4-demo.jar
6. org.eclipse.swt.win32.win32.x86_3.3.0.v3346.jar
7. swtgraphics2d.jar

it is giving error like could not instantiate view in the view.
and giving error in console like
"java.lang.NoClassDefFoundError: org/jfree/data/general/PieDataset"

i Think you only can help because you had experience with same requirement.

Thanks in advance Mr.Dundar.

The following is my view in RCP Project

package rcpchart;

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;

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 void createPartControl(Composite parent) {

JFreeChart chart = createChart(createDataset());
new ChartComposite(parent, SWT.NONE,
chart, true);
}

public void setFocus() {
}

/**
* Creates the Dataset for the Pie chart
*/
private 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;
}

/**
* Creates the Chart based on a dataset
*/
private JFreeChart createChart(PieDataset dataset) {

JFreeChart chart = ChartFactory.createPieChart("Pie Chart Demo 1", // chart
// title
dataset, // data
true, // include legend
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;

}
}

Most likely you modified the JavaBuild-Path in your Project-Settings
instead of doing it with the MANIFEST.MF.
