How to hide empty (value 0%) chartBarClustered ?

[alaglil]

With $serieOb->setDlblNumFormat('#%') I have the % which is only displayed when the value is 0.
Is there a way to hide it if the value is 0?

    $serieOb = new Series($serieName, $serieData);
        $serieOb->setShowSeriesName(false);
        $serieOb->getFill()->setFillType(Fill::FILL_SOLID)->setStartColor(new Color($colorFill));
        $serieOb->getFont()->getColor()->setRGB($colorFont);
        $serieOb->setShowValue(true);
        $serieOb->setShowPercentage(false);
        //$serieOb->setLabelPosition(Series::LABEL_INSIDEEND);
        // Set Data Label Format For Chart To Display Percent
        $serieOb->setDlblNumFormat('0%');
