How to sort the labels on the x-axis of a combo chart?

Problem Description

In the following combined chart, the x-axis labels are not sorted by time. Can the sorting effect be achieved through sortDataByAxis?

Solution

The function of sortDataByAxis is to sort the data of the series along the axis without affecting the sorting of the axis itself. To display the content on the axis in the desired order, there are two solutions:

Configure the fields in the data to set the domain order of the data to be displayed:

Sort the data in advance according to the display order.

Code Examples

const spec = {
  type: 'common',
  seriesField: 'color',
  data: [

          sortIndex: 0
        }
