Controlling colour when using bar3DPlot

How can I control colour on my chart, I am using bbar3DPlot and I would like to have different colour on each bar. If I use pie3DPlot then it renders with different colour and I am trying to have the same thing with bar3DPlot. I am attaching my .jrxml file. Any help would be greatyly appreciated.
Thanks in advance.

You could use a chart customizer implementation to control the color of chart bars, just like we do in the /demo/samples/charts/BarChartReport

I hope this helps.

Thanks for your suggestion but I have already tried that. The problem is I can't controll colour on each bar, with this customizer the colour is set on whole plot. I got to have differnt colour on each bar. Please help me to solve this problem.

import net.sf.jasperreports.engine.JRChartCustomizer;
import net.sf.jasperreports.engine.JRChart;
import org.jfree.chart.JFreeChart;
import org.jfree.chart.renderer.category.BarRenderer;

import java.awt.*;

public class BarChartCustomizer implements JRChartCustomizer

public void customize(JFreeChart chart, JRChart jasperChart)
BarRenderer renderer = (BarRenderer) chart.getCategoryPlot().getRenderer();

Isn't this solved creating different series? Each series is assigned a color during run time...

All the bars in a single series will be the same color. Otherwise if there is more than one series you won't be able to tell which bars go with which series.

This is Atanu. I am very new in ireport and also in java environment. In the ireport I have designed a template .like this.
please look on attach file
[img size=150]C:\Documents and Settings\Atanu\My Documents\graph.jpeg[/img]
Now I want to plot a line graph on the basis of the each data like t1 t2 ---t5 and lcl, ucl, actual value for each row.
That I have done. Now my problem is that I have to change the color of points of t1 t2 ---t5 on the basis of Lcl and Ucl . If the value of t1 ,or t2 or ----t5 are between Ucl and Lcl the color will be blue. And if it out side of Lcl and Ucl then it will be red..
I want the following figure. Where the upper bold line is Ucl and lower bold line isLcl

Actually I have got a information that for that I have to write a customizer class for chart. Also I have write it .

Now this customize class ok running successfully  with creating jar files.<br />
Now I want to create a logic to  check the value of t1 t2 t3   t5 with respect to UCL and LCL. How can I fetch data from report.<br />
Or is there any other way to do this.<br />
Is there any way to pass value from iReport to customizer class ?<br />
<br />
What should I do. Please please help me. It’s urget for me.<br />
