I found a bug in the PRO version of the library.
In 'Template_chart.php' (examples/easy/) when I try to generate the docx, there is a chart inside.
But when I change the variable $PIECHART$ with $PIECHART2$ in 'TemplateChart.docx' and I change the code:
$docx->addTemplateChart ('PIECHART2', $paramsChart); the graph is not created.
After that, there is no more chart with any variables... and I have to upload the first 'Template_chart.php' wich is contained in the librairy's ZIP file.
Have you any idea ?
