Wouldn't it be possible to assign buttons to category objects? And try using forEach to refer to them using the first parameter instead of the index, I think it would be clearer and it would take less code. What catches my eye is the _ in forEach((_, ind)


//Creating space for buttons
chart.yAxis[0].update({
max: chart.yAxis[0].dataMax * 1.75
});

//Calculating sums for each category in xAxis
let sumTable = Array.from({ length: chart.yAxis[0].series.length }, () => 0);
chart.yAxis[0].series.forEach(serie => {
serie.yData.forEach((value, index) => sumTable[index] += value);
});

//Adding dataLabels based on sumTable
chart.xAxis[0].series[0].data.forEach((serie, index) => serie.update({
dataLabels: [{
inside: 'false',
align: 'right',
x: 50,
format: `${Math.floor(sumTable[index] / 1000)} K`
}]
