This is a workaround for the issue reported here https://github.com/highslide-software/highcharts.com/issues/1551

gistfile1.js

var _this = this;
chart_options = {
 chart:{},
 plotOptions:{},
 series:{
  cursor: 'pointer',
  point: {
   events: {
    click: function() {
     // do your awesome magic here
    },
    mouseOver: function(){
     if('ontouchstart' in document.documentElement){
      _this.touch_count += 1
      if(_this.touch_count % 2 == 0){ // the mouseover decides to send a double event, so you use the first
       _this.touch_count = 0
       // do your awesome magic here
      }
     }
    }
   }
  }
 }
}
