where to put Customizer class for the Chart ?

2006-02-09 06:51

Hi,

I want to use the Customizer class for the Charts to set the Colors & for the Orientation of the Labels on the Axis.

but Where should I place this Customizer Class ? I have put in class path, same directory as JRXML file, in the Lib folder along with other Jars ? nothing works . I am always getting the ClassNotFound EXCEPTION !!

One thing remaining is putting the Customizerclass.java into the JAR file itself ?

Pls Advice on what to do here ?

Thanks,

Sunil

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 .

import net.sf.jasperreports.engine.*;

import org.jfree.chart.renderer.category.LineRenderer3D;
import java.awt.*;
import net.sf.jasperreports.engine.JRChart;
import net.sf.jasperreports.engine.JRChartCustomizer;
import org.jfree.chart.JFreeChart;

import java.awt.Color;
import net.sf.jasperreports.engine.JRChart;

import org.jfree.chart.JFreeChart;

import org.jfree.chart.axis.CategoryLabelPositions;
import org.jfree.chart.plot.CategoryPlot;
import org.jfree.chart.renderer.category.BarRenderer3D;
import java.lang.Object;
 


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.

Hi

If you are using iReport then whatever chart you are using ,in that chart's property you will find a field to put the name of the customizer class.And you have to save your customizer.class in the place where you have saved your jrxml/xml file.

You can also create a jar for your class and you can add this jar to classpath of iReport.

I think this may help you (as per my little knowledge).

this is the syntax to convert a class to jar file.

jar cf customizer.jar customizer.class
