Additional or standalone xAxis in anycharts

Question

I need to display a second xAxis on my chart but with different labels. I managed to display a second xAxis by using chart.xAxis(1) but did not managed to change the labels of the second axis. The second xAxis has the labels of the first. A standalone xAxis may be a solution but there is no documentation on that now (https://docs.anychart.com/Dashboards/Standalones#axes).

How do I change the labels of the second xAxis?

Edit: I have an array (["2019-02-18", "2019-02-25"], for example) that I want to set as labels of xAxis.

Answer 1

The demo below can help... more information here

UPDATE: set the extra x-axis and changed the labels afterwards as per questioner's comment.

anychart.onDocumentReady(function() {
