在钻取highchart上添加URL

Question

在向下钻取中添加URL无效，我不确定我的代码是否无效。

                    drilldown: {
                        series: [
                        {"name": "Dec 2018", "id": "Dec 2018", "data": [["Ontime", 2, "ownURL":"show_all_gages.php?sel_company=ALL&mon1=&yr1=&mon2=&yr2=&sel_turnday=7&sel_type=inhousefieldservice&sel_vendor=&sel_month_year=1&sel_passfail=PASS"], ["Delayed", 1, "ownURL":"show_all_gages.php?sel_company=ALL&mon1=&yr1=&mon2=&yr2=&sel_turnday=7&sel_type=inhousefieldservice&sel_vendor=&sel_month_year=1&sel_passfail=FAIL"]]},{"name": "Jan 2019", "id": "Jan 2019", "data": [["Ontime", 6, "ownURL":"show_all_gages.php?sel_company=ALL&mon1=&yr1=&mon2=&yr2=&sel_turnday=7&sel_type=inhousefieldservice&sel_vendor=&sel_month_year=Dec 2018&sel_passfail=PASS"], ["Delayed", 2, "ownURL":"show_all_gages.php?sel_company=ALL&mon1=&yr1=&mon2=&yr2=&sel_turnday=7&sel_type=inhousefieldservice&sel_vendor=&sel_month_year=Dec 2018&sel_passfail=FAIL"]]}
