Hi,

Use a chart customizer.

Hope this helps,
sanda

Code:

public void customize(JFreeChart chart, JRChart jasperChart){  CategoryPlot categoryPlot = (CategoryPlot)chart.getPlot();  categoryPlot.getDomainAxis().setCategoryMargin(0);}

Thanks Sanda for you help..............

But i am facing a little problem.........

this is the chart customizer i am using

import net.sf.jasperreports.engine.JRChart;
import net.sf.jasperreports.engine.JRChartCustomizer;

import org.jfree.chart.JFreeChart;
import org.jfree.chart.plot.CategoryPlot;

public class BarChartCustomizer implements JRChartCustomizer
{

 public void customize(JFreeChart chart, JRChart jasperChart)
     {
   CategoryPlot categoryPlot = (CategoryPlot)chart.getPlot();
   categoryPlot.getDomainAxis().setCategoryMargin(0);
     }

}

But the problem here is the space between two different category axis values is set to zero......... not... the distance between two series..............
PLEASE CHECK OUT THE IMAGE ATTACHED......

Hi,

The other possibility is to remove space between series in a category (you could change BarRenderer with BarRenderer3D if necessary):

BarRenderer renderer = (BarRenderer)categoryPlot.getRenderer();
renderer.setItemMargin(0d);

If this doesn't work, I've no more clues. But you could find by yourself a better solution in JFreeChart library, like I suggested in another post.


Best regards,

Thanks Sanda....... Thank you so so so much.......... it Works:):):)

 

 

One more doubt.......... i am using printwhenExpression tag in my reports..... its working fine in ireports but raising an exception when m compiling it manually using java class.......

 

this is the expression:

 

<printWhenExpression><![CDATA[(($F{participantName}!=null)?$V{CommitteeGroup_COUNT}:0)!=0]]></printWhenExpression>

 

 

where particpant name is a field

 

 

<field name="participantName" class="java.lang.String">

 

<fieldDescription><![CDATA[participantName]]></fieldDescription>

 

</field>

 

 

this is the exception........

 

 

 

 

1. Incompatible conditional operand types Integer and int

 

value = (java.lang.Boolean)(((((java.lang.String)field_participantName.getValue())!=null)?((java.lang.Integer)variable_CommitteeGroup_COUNT.getValue()):0)!=0); //$JR_EXPR_ID=13$

2. Incompatible conditional operand types Integer and int

3. Incompatible conditional operand types Integer and int

 

value = (java.lang.Boolean)(((((java.lang.String)field_participantName.getValue())!=null)?((java.lang.Integer)variable_CommitteeGroup_COUNT.getValue()):0)==0); //$JR_EXPR_ID=25$

Probably you are compiling the report using jdk 1.4 or earlier. To see which java version is used, type java -version in a command line.

In jdk 1.4 or earlier, Integer and int are incompatible types, so you have to call the intValue() method on all your Integer fields, parameters and/or variables.

Hope this helps,

M Using JDK 1.5.0.......... But still facing the same problem:(:(:

[szaharia]

Hi,

This kind of errors still remain related to an older java compiler existing in the classpath.
There are multiple ways to manually compile a report. Did you compiled it in Eclipse? Did you compiled it from scratch in a command line? Or did you use an ant build file?
If you used compiling tools (ant or Eclipse), make sure that the compiler compliance level is set to 1.5.
Also check if the JAVA_HOME env variable, if exists, is pointing to jdk 1.5.

Hope this helps,
sanda
