Is there anyway to have plan dates and actual dates shown as multi layer in Gantt Chart?

[Gopal_Kamath]

I would like to see two parallel bars of planned vs actual against the same task in my Gantt, like this picture below. How can I achieve it?

Hello Gopal,
Right now, Gantt doesn’t have a built-in way to show baselines. But you can use the Gantt API to implement that.
You can use the addTaskLayer method that allows showing any HTML elements in the timeline:

addTaskLayer method | DHTMLX Gantt Docs

Here are examples of the implementation:

Gantt : Samples

DHTMLX - Gantt. addTaskLayer. Show baselines behind tasks on the same rows (8.0)

In the future, the dev team will add a built-in way to show baselines. But I cannot give you any ETA.
