how to put some data option key url on Highchart?

我试着在我的图表栏上添加一些 url 所以当它点击时它会转到另一个页面 但我不知道我应该把选项键放在哪里。请给些建议,这是我的代码

    plotOptions: {

    series: {
        cursor: 'pointer',
        point: {
            events: {
                click: function () {
                    location.href = 'https://xxxxxxxx.com/ratnik2/chart_month.php?m=' +
                        this.options.key;
                }
            }
        }
    },
    column: {
        stacking: 'normal',
        pointPadding: 0.2,
        borderWidth: 0,
        dataLabels:
        {
        enabled:true
        }
    }
},
series: [ {
    name: 'Surat Terbit',
    data: [";
    $query->execute("select month(tanggal), count(*) as jumlah
    from surat where year(tanggal)=year(now())
    and tgl_ttd is not null
    group by month(tanggal)
    order by month(tanggal) asc
    ");

    while ($row = $query->fetch()){
    $isi .= $row["jumlah"].",";
    }

  $isi .="]
  name: '',
  key: ''
  }]

});

看看这个演示:http://jsfiddle.net/gh/get/jquery/1.7.2/highslide-software/highcharts.com/tree/master/samples/highcharts/plotoptions/series-point-events-click-url/

plotOptions: {
    series: {
        cursor: 'pointer',
        point: {
            events: {
                click: function () {
                    location.href = 'https://en.wikipedia.org/wiki/' +
                        this.options.key;
                }
            }
        }
    }
},
