Highcharts mouse over point information

Question

I need the information form mouse over on the point in Highcharts line chart, I tried to use tooltip but there is an error as: function statement requires a name. I have put the formatter in a plotOptions as the onclick function. I don't know if I can use these two options together. I need also to get the line names.

   plotOptions:{
                series:{
                    allowPointSelect: true,
                    point: {
                        events:{
                            click: function(e) {/*$("#displayText").html(e.currentTarget.y)*/ 
                             
                              tooltip: {
	                         formatter: function () {
                             alert(this.x);
                                   }
                                   },
							  }
                        }                        
                    },
					
                }
            },

Answer 1

Ok, I was totally wrong. Here is the answer to retrieve line chart data.

    plotOptions:{
                series:{
                    allowPointSelect: true,
                    point: {
                        events:{
                            click: function() {
                            alert('Category: ' + this.category + ', value: ' + this.series.name ); //this.x+1 is the msgID
                            }
                        }                        
                    },
					
                }
            },
