Changing X Axis Type From Category To Datetime On Drilldown

Is it possible to change a graph's x axis type from category to datetime on drilldown? I have stacked column style graph where each column is a different category. When I click on

Solution 1:

For someone still looking for answer. The solution is:

Define X-axis in an array:

xAxis: [{
          id: 0,
          type: 'category'
        }, {
          id: 1,
          type: 'datetime'
        }]

For each series in drilldown

drilldown: {
          series: [{
            name:"test",
            id:"test",
            xAxis:1, //<---yourdesiredXaxisIDdata: [
              [yourdata]
            ]
          }]
        }

Solution 2:

Unforunately this option is not avaialble, you need to destroy and create new chart.
