How to plot a curve at different time
 

Hi, I am simulating a 3D airfoil and want to plot a pressure curve with time period. I have chosen a time periodic part from Cl curve. and calculated time for T/4,T/2. But now I do not know how to select this time in fluent or in tecplot to plot pressure? As I have T/4 at = 86.25 . Now I want to plot pressure vs this time. How could I DO THIS? Anyone please let me know. Thanking in anticipation.
