Data Label Positions not working for Doughnut Chart

[alaglil]

When I added $series->setLabelPosition(Series::LABEL OUTSIDE END); it doesn't change anything

`
// Generate sample data for second chart
echo date('H:i:s') . ' Generate sample data for chart' . EOL;
$seriesData = ['Monday' => 18, 'Tuesday' => 23, 'Wednesday' => 14, 'Thursday' => 12, 'Friday' => 20, 'Saturday' => 8, 'Sunday' => 10];

// Create a doughnut chart (that should be inserted in a shape)
echo date('H:i:s') . ' Create a non-3D Doughnut chart (that should be inserted in a chart shape)' . EOL;
$doughnutChart = new Doughnut();
$doughnutChart->setHoleSize(43);
$series = new Series('Downloads', $seriesData);
$series->getDataPointFill(0)->setFillType(Fill::FILL_SOLID)->setStartColor(new Color('FF7CB5EC'));
$series->getDataPointFill(1)->setFillType(Fill::FILL_SOLID)->setStartColor(new Color('FF434348'));
$series->getDataPointFill(2)->setFillType(Fill::FILL_SOLID)->setStartColor(new Color('FF90ED7D'));
$series->getDataPointFill(3)->setFillType(Fill::FILL_SOLID)->setStartColor(new Color('FFF7A35C'));
$series->getDataPointFill(4)->setFillType(Fill::FILL_SOLID)->setStartColor(new Color('FF8085E9'));
$series->getDataPointFill(5)->setFillType(Fill::FILL_SOLID)->setStartColor(new Color('FFF15C80'));
$series->getDataPointFill(6)->setFillType(Fill::FILL_SOLID)->setStartColor(new Color('FFE4D354'));

$series->setLabelPosition(Series::LABEL_OUTSIDEEND);

$series->setShowPercentage(true);
$series->setShowValue(false);
$series->setShowSeriesName(false);
$series->setShowCategoryName(true);
$series->setDlblNumFormat('%d');
$series->setSeparator(' > ');
$series->getFont()->getColor()->setRGB('FFFF00');
$series->getFont()->setBold(true);
$doughnutChart->addSeries($series);

// Create a shape (chart)
echo date('H:i:s') . ' Create a shape (chart)' . EOL;
$shape = $currentSlide->createChartShape();
$shape->setName('PHPPresentation Daily Downloads')
    ->setResizeProportional(false)
    ->setHeight(550)
    ->setWidth(700)
    ->setOffsetX(120)
    ->setOffsetY(80);
$shape->setShadow($oShadow);
$shape->setFill($oFill);
$shape->getBorder()->setLineStyle(Border::LINE_SINGLE);
$shape->getTitle()->setText('PHPPresentation Daily Downloads');
$shape->getTitle()->getFont()->setItalic(true);
$shape->getPlotArea()->setType($doughnutChart);
$shape->getLegend()->getBorder()->setLineStyle(Border::LINE_SINGLE);
$shape->getLegend()->getFont()->setItalic(true);
$shape->getLegend()->setPosition(Legend::POSITION_LEFT);
