[Solved]-Is there a way to change the display value in series using highcharts-Highcharts

I was able to find a solution to my problem. Had to add:

tooltip:
                                {
                                        formatter: function ()
                                        {
                                            var text = this.x + ': ' + secondsTimeSpanToHMS(this.y/1000);
                                            return text;
                                        }
                                },

and it gave this result:
