[Solved]-Set column width depending on max datalabel value-Highcharts

You need to use breaks. For example:

xAxis: {
  categories: [''],
  breaks: [{
    from: 0.5,
    to: 0.9,
    breakSize: 0
  }, {
    from: 1,
    to: 1.5,
    breakSize: 0
  }, {
    from: 1.5,
    to: 2,
    breakSize: 0
  }]
}
