Greetings all. I have a vtu file whose output is like this.

I am interested in finding out the height (y) at a given x,z location (horizontal plane) and it’s variation over time, for which I have multiple such vtu files at different times. I was wondering if this is possible to extract in paraview.  
Thanks.
