Select over hvplot and get dataframe

Hey all,
So I’m plotting a dataframe using hvplot.line() when x axis is a timestamp -

And, I wish to be able to select data points over that plot so I’ll be able to analyze that dataframe and show my analysis (in this case I want to show the time difference between the maximum and minimum readings on the x and y axis)
I have looked at these resources and still haven’t figured it out -

Thanks in advance.
