Charts 如何正确使用深入分析图表？

我已经通过手动键入进行了多次深入研究。这里是链接。但是，我需要制作图表，它的数据取自数据库。我已经从谷歌和stackoverflow搜索了其他问题，但我仍然没有得到答案。人们问到他们的数据手动输入到highcharts代码的深入问题，这和我的问题不同，因为我从数据库中获取数据

这是我要放在图表上的表格：

学院2011

部门2011

major2011

这是我的密码：

控制器

        $faculty = (new \yii\db\Query())
            ->select(['Faculty'])
            ->from('facultyin2011')
            ->limit(10)
            ->column();

        $age1 = (new \yii\db\Query())

            ->limit(10)
            ->column();


        $age1 = array_map('floatval', $age1);
        $age2 = array_map('floatval', $age2);

        $data['agedepartment1'] = json_encode($agedepartment1);
        $data['agedepartment2'] = json_encode($agedepartment2);




        $majorstudent = (new \yii\db\Query())
            ->select(['major'])
            ->from('major2011')
            ->limit(10)
            ->column();

        $agemajor1 = (new \yii\db\Query())

        $agemajor1 = array_map('floatval', $agemajor1);
        $agemajor2 = array_map('floatval', $agemajor2);


        $data['ageformajorstudent'] = json_encode($majorstudent);
        $data['agemajor1'] = json_encode($agemajor1);
        $data['agemajor2'] = json_encode($agemajor2);

我要做的第一级图表是教员，第二级是系，第三级是专业

以上代码的结果如下图所示：

上面图表的问题是：图表无法向下钻取，因为我仍然没有放置向下钻取代码。我不知道该怎么说，因为我获取的数据来自数据库中的表。谁能帮我解决这个问题？我可以做些什么来解决这个问题？这对我有很大帮助。提前感谢

深入研究（数据库数据）的第一级和第二级是什么？第一级是教员，第二级是系，第三级是专业@deep3015 Highcharts库有问题吗？或者这只是数据问题吗？highchrts库没有问题。我只是不知道如何编写drildown图表，从数据库@KacperMadej检索数据。你能帮我进行深入研究吗？@Deep3015这里是链接
