Hi.,

please see my code :

// Write the Excel Value
$objReader = PHPExcel_IOFactory::createReader('Excel2007');
$objReader->setIncludeCharts(TRUE);
$objPHPExcel = $objReader->load('Chart_Report.xls');
$objPHPExcel ->setActiveSheetIndex(0);
.
.
.
$objPHPExcel ->getActiveSheet()->setTitle("Project");
PHPExcel_Settings::setZipClass(PHPExcel_Settings::PCLZIP);
$objWriter = PHPExcel_IOFactory::createWriter($objPHPExcel , 'Excel2007');
$objWriter->setIncludeCharts(TRUE);
$objWriter->save($xl_file);
exit;

but the error show on :

Fatal error: Call to undefined method PHPExcel_Reader_Excel2007::setIncludeCharts() in D:\xampp\htdocs\weekly\index.php on line 12
