How to remove box around label in piechart?

Does anyone know how to remove the box/border around label in jasperreport piechart? What do I need to include in the .jrxml file so that the label displayed with no border.

Solution

  • Add a JRChartCustomizer, setting labelOutlinePaint and labelShadowPaint to null in plot

    Example

    Java customizer

    public class NoLabelCustomizer implements JRChartCustomizer{
    @Override
    public void customize(JFreeChart chart, JRChart jrchart) {
        PiePlot plot = (PiePlot) chart.getPlot();
         plot.setLabelOutlinePaint(null);
         plot.setLabelShadowPaint(null);    
    }
}

    jrxml

    <pie3DChart>
    <chart isShowLegend="false" customizerClass="NoLabelCustomizer">
            <reportElement mode="Opaque" x="225" y="0" width="320" height="140" backcolor="#FFFFFF" uuid="23bd26a6-04a4-406f-8a1a-5e1b260cb75d"/>
            <chartTitle/>
            <chartSubtitle/>
            <chartLegend/>
            <anchorNameExpression><![CDATA["Graph"]]></anchorNameExpression>
            <hyperlinkTooltipExpression><![CDATA["Graph"]]></hyperlinkTooltipExpression>
    </chart>
    <pieDataset>
            <keyExpression><![CDATA[$F{User}]]></keyExpression>
            <valueExpression><![CDATA[$F{Rep}]]></valueExpression>
    </pieDataset>
    <pie3DPlot isShowLabels="true">
            <plot/>
            <itemLabel/>
    </pie3DPlot>
</pie3DChart>

    Note the customizerClass="NoLabelCustomizer" on the chart tag
