Highcharts - 一連のデータの 1 つであるツールチップを削除する方法

!

線で矢印を描く

しかし、2 番目のポイントのツールチップを削除したいです。

正確には、1 つの矢印線に 1 つのツールチップのみを表示したい

何か方法はありますか??

コード：

$(function() {

  (function(H) {

    var arrowCheck = false,
        pathTag;

    H.wrap(H.Series.prototype, 'drawGraph', function(proceed) {

      // Now apply the original function with the original arguments, 
      // which are sliced off this function's arguments
      proceed.apply(this, Array.prototype.slice.call(arguments, 1));

      var arrowLength = 15,
        arrowWidth = 9,
        series = this,
        data = series.data,
        len = data.length,
        segments = data,
        lastSeg = segments[segments.length - 1],
        path = [],
        lastPoint = null,
        nextLastPoint = null;

      if (lastSeg.y == 0) {
        lastPoint = segments[segments.length - 2];
        nextLastPoint = segments[segments.length - 1];
      } else {
        lastPoint = segments[segments.length - 1];
        nextLastPoint = segments[segments.length - 2];
      }

      var angle = Math.atan((lastPoint.plotX - nextLastPoint.plotX) /
        (lastPoint.plotY - nextLastPoint.plotY));

      if (angle < 0) angle = Math.PI + angle;

      path.push('M', lastPoint.plotX, lastPoint.plotY);

      if (lastPoint.plotX > nextLastPoint.plotX) {

        if (arrowCheck === true) {

          pathTag = document.getElementById("arrow");
          if (pathTag != null) {
            pathTag.remove(pathTag);
          }
        }

        path.push(
          'L',
          lastPoint.plotX + arrowWidth * Math.cos(angle),
          lastPoint.plotY - arrowWidth * Math.sin(angle)
        );
        path.push(
          lastPoint.plotX + arrowLength * Math.sin(angle),
          lastPoint.plotY + arrowLength * Math.cos(angle)
        );
        path.push(
          lastPoint.plotX - arrowWidth * Math.cos(angle),
          lastPoint.plotY + arrowWidth * Math.sin(angle),
          'Z'
        );
      } else {


        if (arrowCheck === true) {

          pathTag = document.getElementById("arrow");
          if (pathTag != null) {
            pathTag.remove(pathTag);
          }
        }

        path.push(
          'L',
          lastPoint.plotX - arrowWidth * Math.cos(angle),

          lastPoint.plotY - arrowWidth * Math.sin(angle),
          'Z'
        );
      }

      series.chart.renderer.path(path)
        .attr({
          fill: series.color,
          id: 'arrow'
        })
        .add(series.group);

       arrowCheck = true;

    });
  }(Highcharts));



  var chart = new Highcharts.Chart({
    chart: {
      renderTo: 'container',
      defaultSeriesType: 'scatter'
