您可以使用setExtremes事件回调并根据它们的位置更新点。举例来说：

xAxis: {
    events: {
      setExtremes: function(e) {
        this.series.forEach(s => {
          const firstPoint = s.points.find(p => p.isInside);
          const lastModifiedPoint = s.points.find(
            p => p.originalValue || p.originalValue === 0
          );

          if (firstPoint.y !== 0) {
            firstPoint.originalValue = firstPoint.y;
            firstPoint.update({
              y: 0
            }, false);
          }

          if (lastModifiedPoint && lastModifiedPoint !== firstPoint) {
            lastModifiedPoint.update({
              y: lastModifiedPoint.originalValue
            }, false);

            delete lastModifiedPoint.originalValue;
          }
        });
      }
    }
  }
