Highcharts series定义

Posted 2020-10-20

定义series中的数据发现是json格式，

  name: 'cdn',

  data: [<?php echo $type['cdn']?> ]

那么我们可以在后端生成一个数组在js里打印

  [ {"name":"cdn","data":[0]},{"name":"domain","data":[0]},{"name":"ssl","data":[0]} ]

从数据库中循环查询并生成name data键的数组

    $types = $this->model->selectQcloudtype();

            foreach ($types as $key => $type){

                $montharr[$key]['name'] = $type['oProductCode'];

                for ($month= 1;$month<=$maxmonth; $month++){

                    if($month<10){

                        $month=sprintf("%02d",$month);

                    }  //位数不足前补零

                   $result= $this->model->selectQcloudCostcount($syear,$type['oProductCode'],$month);

                    $num = $result['0']['oTotalAmount'] ? $result['0']['oTotalAmount'] : 0;

                    $num = intval ($num)/100; //转换格式、单位

                    $montharr[$key]['data'][$month]=$num;

                }

注意data中要去掉键

                $montharr[$key]['data']=array_values($montharr[$key]['data']);  

注意data里的值为int型 

        $num = intval ($num)
