thanks in advance!

you can use stacklabels formatter , check last tick on xaxis compared current x of stacklabel. if same, bold that.

formatter: function () {                 var ticks = this.axis.chart.xaxis[0].tickpositions,                     len = ticks.length,                     last = ticks[len - 1];                  if(this.x === last)                      return '<span style="font-weight:bold">' + highcharts.numberformat(this.total, 1) + '</span>';                 else                     return highcharts.numberformat(this.total, 1);             },
