$objPHPExcel=$objPHPExcel_new = new PHPExcel();
$objReader = PHPExcel_IOFactory::createReader('Excel2007');
$objPHPExcel = $objReader->load("../Graph_sample.xlsx");



$objWrITer = PHPExcel_IOFactory::createWriter($objPHPExcel,'Excel2007');
$objWriter->save('result.xlsx');

由于大多数用户不希望默认加载图表(加载/保存图表是速度和内存开销),因此您必须使用setIncludeCharts()明确告诉PHPExcel您要加载它们：

$objPHPExcel=$objPHPExcel_new = new PHPExcel();
$objReader = PHPExcel_IOFactory::createReader('Excel2007');
$objReader->setIncludeCharts(TRUE);
$objPHPExcel = $objReader->load("../Graph_sample.xlsx");

写作的时候

$objWriter = PHPExcel_IOFactory::createWriter($objPHPExcel,'Excel2007');
$objWriter->setIncludeCharts(TRUE);
$objWriter->save('result.xlsx');
