[Paraview] Transient point data analysis

[ramaya]

Dear All,
I have a transient simulation results written to individual files. I 
would like to see the evolution of T(temperature) with respect to t 
(time) at a point attached to the body. The body moves with respect to 
time. I tried Plot over line, plot over selection etc gives the plot at 
a fixed coordinates but my points have moved from the initial file. I am 
looking for something like evolution of T on the material coordinates.
At step 0 : My point is at (x, y)
At step 1: My point is at (x,y+deltay1)
At step 3 My point is at (x,y+deltay2)

Please provide me some guidance.

Thanks
