[Solved]-Show value of last point as label or tooltip on Highcharts Stock Chart-Highcharts

You just need to add a simple data formatter to have the datalables to be displayed only on the last datapoint.

plotOptions: {
        series: {
            dataLabels: {
                enabled: true,
                formatter: function(){
                    var isLast = false;
                    if(this.point.x === this.series.data[this.series.data.length -1].x && this.point.y === this.series.data[this.series.data.length -1].y) isLast = true;

                  return isLast ? this.y : '';
                }
            }
        }
    },
