Chart Customizer class

2005-09-15 12:44

I'm trying to turn off the labels for a pie chart and I'm using the JRChartCustomizer interface. It compiles fine and I've got my "customizer" class defined in JRXML and it is in the class path but I get a run time error:

Error filling print... net.sf.jasperreports.engine.JRRuntimeException: com.foobar.utils.ReportChartCustomizer at net.sf.jasperreports.engine.fill.JRFillChart.<init>(JRFillChart.java:253) at net.sf.jasperreports.engine.fill.JRFillObjectFactory.getChart(JRFillObjectFactory.java:464) at net.sf.jasperreports.engine.base.JRBaseChart.getCopy(JRBaseChart.java:430) at net.sf.jasperreports.engine.fill.JRFillElementGroup.<init>(JRFillElementGroup.java:87) at net.sf.jasperreports.engine.fill.JRFillBand.<init>(JRFillBand.java:113) at net.sf.jasperreports.engine.fill.JRFillObjectFactory.getBand(JRFillObjectFactory.java:287) at net.sf.jasperreports.engine.fill.JRBaseFiller.<init>(JRBaseFiller.java:580) at net.sf.jasperreports.engine.fill.JRVerticalFiller.<init>(JRVerticalFiller.java:92) at net.sf.jasperreports.engine.fill.JRVerticalFiller.<init>(JRVerticalFiller.java:74) at net.sf.jasperreports.engine.fill.JRFiller.createFiller(JRFiller.java:113) at net.sf.jasperreports.engine.fill.JRFiller.fillReport(JRFiller.java:57) at net.sf.jasperreports.engine.JasperFillManager.fillReport(JasperFillManager.java:247) at net.sf.jasperreports.engine.JasperFillManager.fillReport(JasperFillManager.java:163) at it.businesslogic.ireport.IReportCompiler.run(IReportCompiler.java:625) at java.lang.Thread.run(Unknown Source)

Has anyone has success using the customizer class with charts?

TIA

Hi,

Make sure your chart customizer class is available in the

classpath at runtime and that it has an empty constructor because we are instantiating it using Reflection.

I hope this helps.

Hi,

After further investigating this we found out

there is a small bug in our latest release

and iReport and the other tools that use

JasperReports are not able to instantiate the

chart customizer class.

This has been fixed in the CVS and will be part

of the next release.

Thank you,

Teodor

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=150]C:Documents and SettingsAtanuMy Documentsgraph.jpeg

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

size=150]C:Documents and SettingsAtanuMy Documentsdata.jpeg

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

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.
