Are there any events on the chart which fires on zoom starts and zoom ends which i can use to calculate the time taken for the zoom operation.

This is going to be very difficult to measure.

You can get notification when a zoom starts and ends by using one of these techniques:

However, this simply gives you a notification that a zoom occurred. You won’t get a notification when a zoom ends and the chart has redrawn, unless you also subscribe to Axis.VisibleRangeChanged or/or SciChartSurface.Rendered. But then it’s difficult to know if the Rendered event was fired because of your zoom, or because of something else.

In short, I don’t think you will be able to do this easily, but, hopefully there are some ideas above to test out.
