Thread: Can't get JFreeChart to work

Hi all,
I've wasted the whole day trying to get JFreeChart to work in NetBeans, in both Windows and Linux and have completely failed. Does anyone have any experience with this? I don't care what OS gets it up and running, I just need to use it for my GUI. I followed the help pdf and read the README and followed the instructions to the letter, but the classpaths don't seem to recognised.

Any help would be massively appreciated

Ps. I'm not tied to NetBeans, any method would work

Used the jar file from JKLJar File Download and it worked fine, maybe the newest one has some bugs?
Anyway, 13 works fine for me

Hi Igniteflow,

Download Jfreechar from here Download JFreeChart from SourceForge.net

once downloaded extract the file onto your desktop!,once extracted,open up netbeans -> right click on the libraries(place on left side of your netbeans project)->select add jar/folder->dialog box pops up,navigate to the lib folder of your downloaded jfreechart-1.0.13,and add them all.now all the required libraries are placed.

Once you are done with that,try this code out!

public class PieChart extends JFrame {
 
 
	public PieChart(String applicationTitle, String chartTitle) {
        super(applicationTitle);
        // This will create the dataset
        PieDataset dataset = createDataset();
        // based on the dataset we create the chart
        JFreeChart chart = createChart(dataset, chartTitle);
        // we put the chart into a panel
        ChartPanel chartPanel = new ChartPanel(chart);
        // default size
        chartPanel.setPreferredSize(new java.awt.Dimension(500, 270));
        // add it to our application

            dataset,                // data
            true,                   // include legend
            true,
            false
        );
 
        PiePlot3D plot = (PiePlot3D) chart.getPlot();
        plot.setStartAngle(290);
        plot.setDirection(Rotation.CLOCKWISE);
        plot.setForegroundAlpha(0.5f);
        return chart;
 
    }
 
 
 
 
}

	        demo.pack();
	        demo.setVisible(true);
