Graphs using JFreeChart

Hi Friend,

Try the following code:

import java.awt.*;
import java.text.*;
import javax.swing.*;

import org.jfree.chart.*;
import org.jfree.chart.axis.DateAxis;
import org.jfree.chart.plot.XYPlot;
import org.jfree.chart.renderer.xy.*;
import org.jfree.data.time.*;
import org.jfree.data.xy.XYDataset;
import org.jfree.ui.*;


public class LineChart extends ApplicationFrame {

public LineChart(String title) {
super(title);
TimeSeries s1 = new TimeSeries("Power", Day.class);
s1.add(new Day(15,12, 2009), 150);
s1.add(new Day(16,12, 2009), 200);
TimeSeriesCollection dataset = new TimeSeriesCollection();
dataset.addSeries(s1);
dataset.setDomainIsPointsInTime(true);

JFreeChart chart = ChartFactory.createTimeSeriesChart(
"Power consumed by a consumer in specific date",
"Date",
"Power",
dataset,
true,
true,
false
);
ChartPanel chartPanel = new ChartPanel(chart, false);
chartPanel.setPreferredSize(new java.awt.Dimension(500, 270));
chartPanel.setMouseZoomable(true, false);
setContentPane(chartPanel);
XYPlot plot = (XYPlot) chart.getPlot();
XYItemRenderer r = plot.getRenderer();
if (r instanceof XYLineAndShapeRenderer) {
XYLineAndShapeRenderer renderer = (XYLineAndShapeRenderer) r;
}

DateAxis axis = (DateAxis) plot.getDomainAxis();
axis.setDateFormatOverride(new SimpleDateFormat("dd-MM-yyyy"));
}
public static void main(String[]args){
LineChart chart = new LineChart("Chart");
chart.pack();
chart.setVisible(true);

}

}
