Highcharts Gantt change first day of the week

Question

I use Highcharts Gantt charts and I need to change the first day of the week displayed on the X-Axis. By default, the week starts on Monday but I need the week to start on Wednesday (until next Tuesday). How can I achieve that ? On the following example https://jsfiddle.net/vegaelce/xqp6whyj/ I tried to change the startOfWeek: 3 but with no incidence. Thanks in advance

Answer 1

You need to set startOfWeek, but for the second x-axis. For example:

  xAxis: [{
    currentDateIndicator: true,
    min: today - 3 * day,
    max: today + 18 * day
  }, {
    startOfWeek: 3
  }]
