extracting data in tecplot

peter

I calculated unsteady problem about pressure surge with fluent 6.3. And now i'm trying to see the pressure changes in a certain point for time goes by.

i used sliding mesh with time step of 0.5sec, and the total time is 25sec. i loaded whole data files and can play the animation of pressure changes in tecplot 360, but don't know how to get information of pressure property in the animation. I'd like to ask some advice how to extract the pressure data in a certain point for whole data files at once.

can anyone help me step by step?

thank you very much.
