Highcharts: how to select column (crosshairs) on mouseover xAxis labels - highcharts

Question

How I can select column (crosshairs) on mouseover xAxis labels?
I can mouseover label, but don't know how to select column.
$(document).on('mouseover', '.highcharts-axis:eq(' + (axisCount - 1) + ') text, .highcharts-axis-labels:eq(' + (axisCount - 1) + ') text', function () {
console.log('mouseover');
// hover current column - crosshairs
});

You can wrap crosshairs function and modify height of plotted element.
(function (HC) {
HC.wrap(HC.Axis.prototype, 'drawCrosshair', function (proceed, e, point) {
var path,
options = this.crosshair,
animation = options.animation,
pos,
attribs,
categorized;
if (
// Disabled in options
!this.crosshair ||
// Snap
((defined(point) || !HC.pick(this.crosshair.snap, true)) === false)) {
this.hideCrosshair();
} else {
// Get the path
if (!HC.pick(options.snap, true)) {
pos = (this.horiz ? e.chartX - this.pos : this.len - e.chartY + this.pos);
} else if (defined(point)) {
pos = this.isXAxis ? point.plotX : this.len - point.plotY; // #3834
}
if (this.isRadial) {
path = this.getPlotLinePath(this.isXAxis ? point.x : pick(point.stackY, point.y)) || null; // #3189
} else {
path = this.getPlotLinePath(null, null, null, null, pos) || null; // #3189
}
if (path === null) {
this.hideCrosshair();
return;
}
// Draw the cross
if (this.cross) {
//overwrite a height
path[5] = point.series.chart.containerHeight;
this.cross.attr({
visibility: VISIBLE
})[animation ? 'animate' : 'attr']({
d: path
}, animation);
} else {
categorized = this.categories && !this.isRadial;
attribs = {
'stroke-width': options.width || (categorized ? this.transA : 1),
stroke: options.color || (categorized ? 'rgba(155,200,255,0.2)' : '#C0C0C0'),
zIndex: options.zIndex || 2
};
if (options.dashStyle) {
attribs.dashstyle = options.dashStyle;
}
this.cross = this.chart.renderer.path(path).attr(attribs).add();
}
}
});
})(Highcharts);
