            color: 'green',

推荐答案

您可以使用chart.xAxis[0].scrollbar.group.translateX和chart.xAxis[0].scrollbar.group.translateY获取滚动条的位置，例如:

You can get position of the scrollbar using chart.xAxis[0].scrollbar.group.translateX and chart.xAxis[0].scrollbar.group.translateY, for example: https://codepen.io/anon/pen/KeBxNj?editors=1010

摘要:

var chart = Highcharts.chart('container', {
  chart: {
    type: 'bar',
    marginLeft: 150,
    events: {
      load: function () {
        var scrollbar = this.xAxis[0].scrollbar,
            bbox;
        // Render:
        this.customLabel = this.renderer.text('<span style="font-weight:600;"> 1-21 </span>', 0, 0).attr({
          zIndex: 5
        }).add();
        // Get bbox
        bbox = this.customLabel.getBBox();

        // Position label
        this.customLabel.attr({
          x: scrollbar.group.translateX - bbox.width,
          y: scrollbar.group.translateY + bbox.height
        });
      }
    }
  },
  ...
});
