Answer 1

I have searched lot off and finally got idea, That Chart is XML code and loaded in Excel. So phpspreadsheet is already doing same for chart, phpspreadsheet itself generates xml code.

$objWriter->startElement('c:dLblPos');
$showVal = (empty($chartLayout)) ? 0 : $chartLayout->getShowVal();
$objWriter->writeAttribute('val', 't');
$objWriter->endElement();

We just need to add this lines in Phpspreadsheet/Writer/Xlsx/Chart.php on Line No : 361

Here You can set position of label for values.

"t" : Top

"b" : Below

Thanks
