[Solved]-Highcharts: Shared tooltip formatter this.points[i]-Highcharts

When you want to display the individual data points for stacked graphs with a shared tooltip, you have to loop through the individual points and build up the tooltip markup.

    tooltip: {
        shared: true,
        formatter: function () {
            var points = this.points;
            var pointsLength = points.length;
            var tooltipMarkup = pointsLength ? '<span style="font-size: 10px">' + points[0].key + '</span><br/>' : '';
            var index;
            var y_value_kwh;

            for(index = 0; index < pointsLength; index += 1) {
              y_value_kwh = (points[index].y/1000).toFixed(2);

              tooltipMarkup += '<span style="color:' + points[index].series.color + '">\u25CF</span> ' + points[index].series.name + ': <b>' + y_value_kwh  + ' kWh</b><br/>';
            }

            return tooltipMarkup;
        }
    }
