Can't hide marker on line chart for pptx (0.7.0) #211
Description
Hi,
I'm trying to hide the marker from a line chart, however, setting:
$lineMarker->setSymbol(\PhpOffice\PhpPresentation\Shape\Chart\Marker::SYMBOL_NONE);
seems not enough.
I've solved this issue by adding the following else clause in the writeSeriesMarker function of PptCharts.php file:
else {
$objWriter->startElement('c:marker');
$objWriter->startElement('c:symbol');
$objWriter->writeAttribute('val', $oMarker->getSymbol());
$objWriter->endElement();
$objWriter->endElement();
}
