Can PHPword show Pie Chart in percenage with two decimals? - php

Question

I use PHPword class to create Word file in PHP.
Can you create Pie chart to show value in percentage with two decimals?
$c3 = array('Expensive kW', 'Cheap kW');
$s3 = array($expensive, $cheap);
$tablePie2Charts = $section->addTable('Chart');
$tablePie2Charts->addRow();
$stylePie2Chart = array(
'width' => Converter::inchToEmu(5),
'height' => Converter::inchToEmu(3),
'valueAxisTitle' => 'Last month consumed in kW',
'showLegend' => true,
'dataLabelOptions' => array(
'showCatName' => false,
'showVal' => false,
'showPercent' => true
)
);
$c1 = $tablePie2Charts->addCell()->addChart('pie', $c3, $s3, $stylePie2Chart);

I also encountered the same problem.But i can't find an api to support it.
And here my solution:
edit the file /PhpOffice/Phpword/Writer/Word2007/Part/Chart.php
near the line 250. Insert the code
$xmlWriter->writeElementBlock("c:numFmt",['formatCode'=>'0.00%','sourceLinked'=>'0']);
between
$xmlWriter->startElement('c:dLbls');
and
foreach ($style->getDataLabelOptions() as $option => $val) {
It finally look like that:
$xmlWriter->startElement('c:dLbls');
$xmlWriter->writeElementBlock("c:numFmt",['formatCode'=>'0.00%','sourceLinked'=>'0']);
foreach ($style->getDataLabelOptions() as $option => $val)
if you just want it in pie chart and you should:
if ('pie' === $this->element->getType()){
$xmlWriter->writeElementBlock("c:numFmt",['formatCode'=>'0.00%','sourceLinked'=>'0']);
}
You can change the formatCode like 0.0% 0.00% 0.000% whatever you want.
If someone find the better way,plz tell me,thanks.
