javascript - Trouble getting unique tooltip based on X axis values in highcharts line graph -


i'm trying make graph in points having different x axis values have different tooltip .the 1st 2 points of series have same tooltip though x axis values different.i.e points under month of jan should have "11st comment" tooltip,points under feb should have "22nd comment" tooltip on , forth if x axis values same not y axis values..

the current computational logic tooltip depends upon y axis values.as long y axis values changing tool tip changes accordingly.this happens because of statement"this.y" in below code..

the problem logic long y axis values distinct tooltip works properly,the moment 2 consecutive points of series have same y axis values tooltip not change when x values different...

to make tooltip change acoording x axis values replacing "this.y" "this.x" desired change not happening.can please tell me how make change?

the tool tip code..

       tooltip: {        formatter: function () {         var seriei = this.series.index;       var index = datavalues.indexof(this.y);      var index1= datavalues2.indexof(this.y);       debugger;         var comment = "";         if (seriei == 0) {             comment = $("#ppform.textarea:eq(" + (index) + ")").val();         } else {            //comment = "second serie matched!";             comment = $("#ppform.textarea:eq(" + (index1) + ")").val();         }         /*return ''+ this.x +             '</b> <b>' + this.y + '</b> -->' + comment;*/         return '-->'+comment;     } }

the js fiddle is... http://jsfiddle.net/rbenu/25/

instead of using index datavalues use index categories, way: http://jsfiddle.net/rbenu/39/

tooltip: {         formatter: function () {             var seriei = this.series.index;             var index = categories.indexof(this.x);             var comment = $("input:eq(" + (index) + ")").val();             return '-->'+comment;         }     },
