Answer 1

Tell PHPExcel that you want to include charts when reading and writing
Assuming that the chart is defined in your template
require_once '../Classes/PHPExcel.php';
$fileType = 'Excel2007';
$fileName = 'Result.xlsx';
// Read the file (including chart template)
$objReader = PHPExcel_IOFactory::createReader($fileType);
$objReader->setIncludeCharts(TRUE);
$objPHPExcel = $objReader->load($fileName);
// Change the file
$objSheet = $objPHPExcel->setActiveSheetIndex(0);
$objSheet->getCell('A2')->setValue($SumY );
$objSheet->getCell('B2')->setValue($SumR );
$objSheet->getCell('C2')->setValue($SumB );
$objSheet->getCell('D2')->setValue($SumG );
// Write the file (including chart)
$objWriter = PHPExcel_IOFactory::createWriter($objPHPExcel, $fileType);
$objWriter->setIncludeCharts(TRUE);
$objWriter->save('Result.xlsx');
If the chart isn't defined in your template, then you need to create it in your code
