Chart in Java

This example code creates chart with the hlep of jFree chart Library to work with this example you will need jFree chart Library that is available on

import java.awt.Color;

import org.jfree.chart.ChartFactory;

import org.jfree.chart.ChartPanel;

import org.jfree.chart.JFreeChart;

import org.jfree.chart.axis.NumberAxis;

import org.jfree.chart.renderer.xy.XYLineAndShapeRenderer;




import org.jfree.ui.ApplicationFrame;

import org.jfree.ui.RefineryUtilities;

public class Main extends ApplicationFrame {

    public Main(final String title) {


        final XYDataset dataset = createDataset();

        final JFreeChart chart = createChart(dataset);

        final ChartPanel chartPanel = new ChartPanel(chart);

        chartPanel.setPreferredSize(new java.awt.Dimension(700, 470));



    private XYDataset createDataset() {

       //series no. 1 data elements

        final XYSeries series1 = new XYSeries("First");       

        series1.add(1.0, 1.0);

        series1.add(2.0, 4.0);

        series1.add(7.0, 7.0);

        final XYSeriesCollection dataset = new XYSeriesCollection();

        dataset.addSeries(series1);// add series to dataset




        return dataset;       


   // createChart() returns chart 

    private JFreeChart createChart(final XYDataset dataset) {

        final JFreeChart chart = ChartFactory.createXYLineChart(

            "Line Chart",     










        final XYPlot plot = chart.getXYPlot();




        final XYLineAndShapeRenderer renderer = new XYLineAndShapeRenderer();

        renderer.setSeriesLinesVisible(0, false);

        renderer.setSeriesShapesVisible(1, false);


        final NumberAxis rangeAxis = (NumberAxis) plot.getRangeAxis();


        return chart;

  1. if u get any problem then u can post ur comments here.
