Just like in my chart example. You're need to create a customizer to do this.

I beleive Hozawa is referring to this type of customization.

Implementation and Usage of Chart Customizer Classes for Customizing JFreeCharts in JasperReports

 

[panlj2004]

Hi djohnson53,

I read the doc that you attached link, but it still not clear for me.

1.Implementation of a Chart Customizer Class

Should I create the following class?

import net.sf.jasperreports.engine.JRChart;

import net.sf.jasperreports.engine.JRChartCustomizer; 

......... rangeAxis.setTickMarkOutsideLength(2.5f); }

}

 

2. How to create a class?

3. There are some guide in Jaspersoft-Studio-User-Guide.pdf

where should I write this passage net.sf.jasperreports.engine.JRChartCustomizer

Currently, JasperReports Server takes advantage of only a small portion of the capabilities of the JFreeChart

library. To customize a graph, you must write a class that implements the following interface:

net.sf.jasperreports.engine.JRChartCustomizer

The only method available from this interface is the following:

public void customize(JFreeChart chart, JRChart jasperChart);

It takes a JFreeChart object and a JRChart object as its arguments. The first object is used to actually produce

the image, while the second contains all the features you specify during the design phase that are relevant to the

customize method.

 

waiting for your reply, thank you
