Highcharts warning #15 for Bar Chart on update

[anikolaev]

Expected behaviour

There is a simple Bar chart. After update of category name (and values) it is expect that chart is updated and that order of values is not important.

Actual behaviour

Highcharts warning #15 (Highcharts expects data to be sorted) shows up in console. 9.1.0 had bug that showed error "Highchart is not defined" but it was fixed in 9.1.1 or 9.1.2. But this warning is also unexpected. It seems everything is correct in the config:

var data1 = [
  {name: 'a', y: 1},
  {name: 'b', y: 2},
  {name: 'c', y: 3},
];

var data2 = [
  {name: 'a', y: 1},
  {name: 'b2', y: 2},
  {name: 'c', y: 3},
];


let chart = Highcharts.chart('container', {
  chart: {
    type: 'bar'
  },
  xAxis: {
    type: 'category',
  },

  series: [{
    data: data1
  }],
});

document.getElementById('update').addEventListener('click', () => {
  chart.update({
    series: [{
      data: data2
    }],
  });
});

Hi @anikolaev

Thank you for reporting the problem.

Internal note:
It looks like the error fired when the new data is not matching the old categories, but later the categories are based on the new data and everything works correctly.
