Customize xAxis labels in Gantt chart

[leonaedelinski]

Hello,

Is it possible to customise (set) xAxis labels to be same interval and width, for example, the label string to be incremented by 2.5 min each. Here is design example for it. How is it possible to achieve this?

Hi, welcome to our forum!

You need to set xAxis.units property in combination with xAxis.tickInterval to set such an interval. And to set this formatting for labels you need to use xAxis.labels.formatter() callback function.

Demo: https://jsfiddle.net/BlackLabel/jh6bm7yz/
API: https://api.highcharts.com/highcharts/xAxis.units

Best regards!
