在highcharts工具提示中设置其他信息

我正在做一个columnrange highchart，我的json示例数据如下：

{
    "name": "PW (md.h24mi)",
        "data": [
        [320, 320.06],
        [319.05, 319.1],
        [319.05, 319.1],
        [319.05, 319.1],
        [319.05, 319.1],
        [319.05, 319.1],
        [319.05, 319.1],
        [319.05, 319.1],
        [319.05, 319.1],
        [319.05, 319.1],
        [319.05, 319.1],
        [320, 320.04]
    ],
        "PW": [
        ["PW0000025090"],
        ["PW0000025158"],
        ["PW0000025160"],
        ["PW0000025171"],
        ["PW0000025172"],
        ["PW0000025161"],
        ["PW0000025173"],
        ["PW0000025159"],
        ["PW0000025164"],
        ["PW0000025170"],
        ["PW0000024827"],
        ["PW0000024461"]
    ],
        "GROUP": [
        ["IT"],
        ["Sierra"],
        ["Sierra"],
        ["RF Engineers"],
        ["RF Engineers"],
        ["Sierra"],
        ["RF Engineers"],
        ["Sierra"],
        ["RF Engineers"],
        ["RF Engineers"],
        ["Sierra"],
        ["IP"]
    ],
        "worksum": [
        ["Call Back Assist (CBA) Modification"],
        ["TMA Installation"],
        ["TMA Installation"],
        ["TMA Installation"],
        ["TMA Installation"],
        ["TMA Installation"],
        ["TMA Installation"],
        ["TMA Installation"],
        ["TMA Installation"],
        ["TMA Installation"],
        ["TMA Installation"],
        ["Upgrade Consumer Wimax Firewall Modules to R77.10"]
    ]
}

如何在工具提示中显示“PW”和“worksum”？我试过下面的代码，但是没有

    tooltip: {
           formatter: function() {
    var point = this.points[0];
    return '<b>'+ point.x +'<br />'
        +point.PW + '<br />'
        +point.worksum + '<br />'
        +'</b><br />Duration:'+ point.series.data[0].low +' - '+ point.series.data[0].high;
},
shared: true

           }

工具提示：{
格式化程序：函数（）{
var point=此点[0]；
返回“+point.x+”

+point.PW+“
”
+point.worksum+“
”
+'
持续时间：'+point.series.data[0]。低+'-'+point.series.data[0]。高；
},
分享：真的
}

您已将PW和worksum设置为串联，因此您可以通过

point.series.options.PW/worksum

访问工具提示。然后需要提取相应的值（使用

this.x

）。仅此而已：

工具提示：{
格式化程序：函数（）{
var point=此.points[0]，
系列=点系列，
PW=series.options.PW[point.x]，
worksum=series.options.worksum[point.x]；
返回'+point.x+'
'+PW+'
'+worksum+'
'+'
持续时间：'+point.series.data[0]。低+'-'+point.series.data[0]。高；
},
分享：真的
},

   tooltip: {
       formatter: function () {
           var point = this.points[0],
               series = point.series,
               PW = series.options.PW[point.x],
               worksum = series.options.worksum[point.x];
           return '<b>' + point.x + '<br />' + PW + '<br />' + worksum + '<br />' + '</b><br />Duration:' + point.series.data[0].low + ' - ' + point.series.data[0].high;
       },
       shared: true

   },
