Answer 1

This can be done by using the load event like this:
chart: {
type: 'area',
inverted: false,
events: {
load: function() {
let pointLabelPositions = []
let labelSeries = this.series[0]
let otherSeries = this.series[1]
for (var i = 0; i < labelSeries.data.length; i++) {
pointLabelPositions.push({
dataLabels: {
y: (otherSeries.data[i].plotY - labelSeries.data[i].plotY) / 2
}
})
}
labelSeries.update({
data: pointLabelPositions
})
}
}
},
$(function() {
$('#container').highcharts({
chart: {
type: 'area',
inverted: false,
events: {
load: function() {
let pointLabelPositions = []
let labelSeries = this.series[0]
let otherSeries = this.series[1]
for (var i = 0; i < labelSeries.data.length; i++) {
pointLabelPositions.push({
dataLabels: {
y: (otherSeries.data[i].plotY - labelSeries.data[i].plotY) / 2
}
})
}
labelSeries.update({
data: pointLabelPositions
})
}
}
},
