Chart Customizer pdf export

2006-03-10 05:27

Hi,

I need to create a chart report with multiple axis. I have created a Chart customizer class which adds the second axis and it shows up in the HTML report OK. When I export the report to pdf only some of the values the Customizer class has changed are valid. For example the colors of the bars has changed but the second axis doesn't show up in the pdf.

 

Any help would be higlhy appreciated since I'm eager to solve this

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 .

 

Code:

import net.sf.jasperreports.engine.*;

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.
