Bar Chart Problem

[Rajnesh]

Hi all
I want to create a bar chart using XYPLot but wht happen the different bars overlapped each other .Iwant to display every bar separately as in the Category plot .Is any soln for this problem
here is the code
package chart;



import java.awt.Color;
import java.text.NumberFormat;

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.labels.StandardXYToolTipGenerator;
import org.jfree.chart.plot.PlotOrientation;
import org.jfree.chart.plot.XYPlot;

public class BarChartDemo extends ApplicationFrame {

public BarChartDemo(final String title) {

super(title);

final IntervalXYDataset dataset = createDataset();
final JFreeChart chart = createChart(dataset);
final ChartPanel chartPanel = new ChartPanel(chart);
chartPanel.setPreferredSize(new java.awt.Dimension(500, 270));
setContentPane(chartPanel);

}

private IntervalXYDataset createDataset() {

final XYSeries series1 = new XYSeries("First");
series1.add(1.0, 1.0);

}

// create the chart...

// NOW DO SOME OPTIONAL CUSTOMISATION OF THE CHART...
chart.setBackgroundPaint(Color.white);


// get a reference to the plot for further customisation...

plot.setDataset(1,createDataset2());

renderer.setToolTipGenerator(new StandardXYToolTipGenerator());
plot.setRenderer(renderer);

// OPTIONAL CUSTOMISATION COMPLETED.
ValueAxis valAxis=(ValueAxis)plot.getDomainAxis();
valAxis.setRange(1.0,15.0);///////////Here we set the range of X Axis
valAxis=(ValueAxis)plot.getRangeAxis();

// NumberAxis numAxis=(NumberAxis)plot.getRangeAxis();

}


public static void main(final String[] args) {

final BarChartDemo demo = new BarChartDemo("Bar Chart");
demo.pack();
RefineryUtilities.centerFrameOnScreen(demo);
demo.setVisible(true);

}

}
Awaiting for ur reply
Thanx

You can use the ClusteredXYBarRenderer for this.
