We have Dynamic chart to report generation, using source data export needs to work with several types of exports like pdf,excel,csv..

below is my chart code:

            $graphClassName::create(array(
                "title"=>$report_name,
                "dataSource"=>$result,
                "columns"=>$columns1,
                "colorScheme"=>$colors,
                "options"=>array(
                "isStacked"=>true,
                )
            ));

I don't want to create table just using chart source data array i want to export data
