JFree Bar Chart

[zain.nabi]

I have created a bar chart using Jasper Studio. The bars currently are thin and and all have a different colour. How do I set each bar to a width of 1cm and all the same colour. Please view current image of the graph. Also herewith is my customizer class in which I created in Eclipse:

package Customizer

import org.jfree.chart.JFreeChart;

import net.sf.jasperreports.engine.JRChart;

import net.sf.jasperreports.engine.JRChartCustomizer;

public class CustomLegendList implements JRChartCustomizer

{

public void customize(JFreeChart chart, JRChart jrChart)

{

CategoryPlot cplot = (CategoryPlot)chart.getPlot(); cplot.setBackgroundPaint(SystemColor.inactiveCaption);//change background color //set bar chart color ((BarRenderer)cplot.getRenderer()).setBarPainter(new StandardBarPainter());

BarRenderer r = (BarRenderer)chart.getCategoryPlot().getRenderer();

r.setSeriesPaint(0, Color.blue);

}

}
