@gaurav-sharma6,

Zooming seems to be working fine without any error. Can you kindly create JSFiddle reproducing the issue and share it with us so that we can look into the code / chart-options being used, run it at our end to understand the issue better and help you out?

From what we have observed, sometimes things get delayed mostly when we are not able to reproduce the issue or not able to understand the exact requirements or the solution that we provide may not work properly due to the variation in chart-options being used by you and us.

Having a JSFiddle helps us in figuring out the scenario better and help you out accordingly.
