如何解决不工作的高级图表？

Question

我想让highcharts多次向下钻取。第一是教师，第二钻是部门，第三是主要。我从数据库中获取数据。但是当我运行我的代码时，结果并没有像我预期的那样工作。下钻图表显示不完全如下图所示：

我期望的结果如下图所示。我按照此链接http://jsfiddle.net/rhhh2sg3/1/

手动输入，制作下面的图表

但我想让图表不是手动输入的，因为我想从数据库中获取数据。

这是我放到highcharts的表格：

facultyin2011

department2011

major2011

也许，我的代码中出现了问题：

$(function () {

    // Create the chart
    $('#containers').highcharts({
        chart: {
            type: 'column'
        },
        title: {
            text: 'Basic drilldown'
        },
        xAxis: {
            categories: $ageforfacultystudent

        },

        legend: {
            enabled: false
        },

        plotOptions: {
            series: {
                borderWidth: 0,
                dataLabels: {
                    enabled: true,
                }
            }
        },

        series: [
            {
                name: 'lessthan25',
                data: $age1,

            },
            {
                name: 'btween25to29',
                data: $age2,

            }],

        drilldown: {

            series: [{
                id: 'department1',
                name: 'lessthan25',
                data: [{
                    name: 'Departemen',
                    data: $agedepartment1,
                    drilldown: 'major1'
                }
                ]
            }, 
            {
                id: 'department2',

                data: [
                {

                    drilldown: 'major2'
                }
                ]
            },
            {

                id: 'major1',
                data: $agemajor1
            },
            {

                id: 'major2',
                data: $agemajor2
            }]
        }
    })
});

我也不知道如何对部门进行分类，因为部门是教职员工。 我可以像下面的例子一样对教员进行分类，因为教师图表不是任何图表的子图。

示例是这样的：

$('#containers').highcharts({


 chart: {
        type: 'column'
    },
    title: {
        text: 'Basic drilldown'
    },
    xAxis: {
        **categories: $ageforfacultystudent**

    },

表专业也是同样的问题。如何将专业分类到图表，因为专业是分部门？

请帮我解决这个问题。提前致谢
