I have found a solution for your problem! Sebastian Bochan gave me some ideas. You need to separate xAxis and set a different type to each one. So, here you have to add your categories as Highcharts's way.

xAxis: [{
         id: 0,
         type: 'datetime'
         id: 1,
         type: 'categories',
         categories: data.categories

Then you have to add this code in your serie to link it with your new Axis.

drilldown: {
      series: [{
        name: "test",
        id: "test",
        xAxis: 1, // <--- your desired X axis ID
        data: [
          [your data]

Probably you'll see a small difference on bottom chart, but all works for me.

I hope this help to you ;)


You need to add this to your xAxis:

labels: {
        formatter: function() {
              return Highcharts.dateFormat('%a %d %b', this.value);
