Get axis data on selection and provide drilldown of selected data

I’m plotting a time-series data. I need to provide drilldown of the selected data which is already available. My problem is I don’t want to load the entire data as it might put extra load on the front end. So I’m trying to figure out a way to perform the zoom-in functionality through an API call. To do that I first need to know the selected axis data. Is there a way to get the selected axis data(not coordinates) once the user performs selection on the graph? Thanks in advance
