Domanda

When printing the sub reports in Main Report.

I am using Jasper API for creating main report and adding the compiled sub report in the main report. Main report is compiling fine. But graphs are repeated the number of data in the data source.

If Data source (My data source is JRBeanCollectionDataSource) has 6 then it prints 2 set of 2 overlapping graph and 2 graphs below it

I am calling Sub reports from Group section of report Class to design Main report

public class JasperDesignForTemplate {
    public JasperDesign design() throws Exception {

        // set basic design for main report
        JasperDesign jasperDesign = new JasperDesign();
        jasperDesign.setName("simpleReport");
        jasperDesign.setPageWidth(595);
        jasperDesign.setPageHeight(842);
        jasperDesign.setColumnWidth(270);
        jasperDesign.setColumnSpacing(15);
        jasperDesign.setLeftMargin(20);
        jasperDesign.setRightMargin(20);
        jasperDesign.setTopMargin(30);
        jasperDesign.setBottomMargin(30);    

        //Parameters

        // field
        JRDesignField bar = new JRDesignField();
        bar.setName("bar");
        bar.setValueClass(java.util.List.class);
        jasperDesign.addField(bar);

        JRDesignField time = new JRDesignField();
        time.setName("time");
        time.setValueClass(java.util.List.class);
        jasperDesign.addField(time);

        JRDesignBand band = new JRDesignBand();

        //Group

Soluzione

Remove group expression $F{count} from 

<groupExpression><![CDATA[$F{count}]]></groupExpression>

If this does not work then remove the whole group expression line from both main and subreport.
