Howto pass parameters to JRChartCustomizer?

2006-05-31 09:31

Hi,

 

I've setup my JRAbstractChartCustomizer but I would like to parameterise it. I know you get use the getParameter() methods.. but where do I set the parameter in my jasper report file?

 

Could someone give a small example.

 

Thanks,

Alan

if you extend "JRAbstractChartCustomizer" you can call this.getParameterValue("paramName");

 

Code:

public class MyChartCustomizer extends JRAbstractChartCustomizer {

	public void customize(JFreeChart chart, JRChart jasperChart) {
		
       Object param = this.getParameterValue("paramName"«»);
        
	}

}

 

Adding parameters has nothing to do with chart creation specifically - look at the documentation for adding a parameter to a report :)

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.

 

size=500]C:Documents and SettingsAtanuMy Documentsdata.jpg

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 is Lcl.

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

import org.jfree.chart.plot.CategoryPlot;

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 OSMOSYS!");

}

 

 

}

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.
