You need to explicitly tell PHPExcel to read and to write charts

$objReader->setIncludeCharts(TRUE);

and

$objWriter->setIncludeCharts(TRUE);

as shown in the examples

EDIT

Explicit spoonfeeding type example

//  Create a reader for an Excel2007 file
$objReader = PHPExcel_IOFactory::createReader('Excel2007');
//  Tell the reader to include charts when it loads a file
$objReader->setIncludeCharts(TRUE);
//  Load the file
$objPHPExcel = $objReader->load("33chartcreate-bar.xlsx");


//  Do some stuff to the file


//  Create a writer for an Excel2007 file
$objWriter = PHPExcel_IOFactory::createWriter($objPHPExcel, 'Excel2007');
//  Tell the writer to include any charts when it saves a file
$objWriter->setIncludeCharts(TRUE);
//  Save the file
$objWriter->save(str_replace('.php', '.xlsx', __FILE__));
