Customizer class

2006-05-30 07:34

Can someone please help me figure out how to use the Customizer class? I have the BarChartReport sample and can not get it to work. I get an error stating that it could not create the chart customizer instance.

Do I simply need to have the Customizer.java file located in the same directory as the report? I assume so since that is how the sample is set up. Do I need to put it in the classpath as well? I tried that with no success. I fear I am missing something simple, but I don't know where to look next.

I am executing with an empty datasource. Here is the error I get:

Error filling print...

Print not filled. Try to use an EmptyDataSource...!

Hi

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

size=150C:Documents and SettingsAtanuMy Documentsgraph.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 .

public class LineChartCustomizer extends JRAbstractChartCustomizer {

	public void customize(JFreeChart chart, JRChart jasperChart) {
		 
		LineAndShapeRenderer renderer = (LineAndShapeRenderer) chart.getCategoryPlot().getRenderer(); 
		
 
        renderer.setSeriesPaint(1, Color.green); 
        renderer.setSeriesPaint(4, Color.orange);        
       
		 chart.setTitle("Setting the title "«»); 
	}        
	 

}

Now this customize class ok running successfully with creating jar files.

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.

Or is there any other way to do this.

Is there any way to pass value from iReport to customizer class ?

What should I do. Please please help me. It’s urget for me.

Any help would be greatly appreciated.

Thanks in advance.
