Is it any way that gantt.scrollTo have a smooth effect?

I knew that scrollTo received only x, y position but is it any way to make scroll to have smooth behaviour?
gantt.scrollTo(xPosition, yPosition)

Hello Olly,
There is no built-in way to make it work that way. You need to implement a custom solution by using Gantt API and Javascript.
Here is an example of how it can be implemented:
