you can catch mouseover / mouseout evenets , use loop find point in other series same x value. use setstate() function allows set i.e hover.

events: {                     mouseover: function () {                          console.log(this);                          var indexs = this.series.index,                             indexp = this.x,                             series = this.series.chart.series;                          switch (indexs) {                             case 0:                                 series[1].data[indexp].setstate('hover');                                 break;                             case 1:                                 series[0].data[indexp].setstate('hover');                                 break;                             case 2:                                 series[3].data[indexp].setstate('hover');                                 break;                             case 3:                                 series[2].data[indexp].setstate('hover');                                 break;                         }                     },                     mouseout: function () {                         var indexs = this.series.index,                             indexp = this.x,                             series = this.series.chart.series;                                  series[1].data[indexp].setstate('');                                 series[0].data[indexp].setstate('');                                 series[3].data[indexp].setstate('');                                 series[2].data[indexp].setstate('');                      }                 }
