laravel使用highcharts传值，前端不显示

后端使用laravel将参数传递给前端，但是前端无法正常显示数据，请问到底是哪里出了问题？

laravel 代码：

 $res = HistoryData::where('product_id','1')->get();
            
            //将获取的数据重新排版
            if(count($res) > 0){
                foreach( $res as $value){
                    $timestamp = strtotime(str_replace('/','-',$value['time']));
                    $data[] = [ $timestamp , $value['cumulativeNet']];
                }
            }
            
            //highchart设置内容
            
            //x坐标轴
            $highchart['xAxis'] = [ 'title' => [ 'text' => '时间' ] ];
            
            //y坐标轴
            $highchart['yAxis'] = [ 'title' => [ 'text' => '净值' ] ];
            
            //数据
            $highchart['series'] = [ 'name'=>'净值' , 'data' => $data ];
            
            $highchart['rangeSelector'] = array( 'selected' => '1' );

前端不现实，无非就是前端展现有问题，或者你提供的数据格式并不是它希望得到的格式。
