Cp plot from fluent to excel
 

I am trying to plot cp against x/c for a 3d airfoil, and when i extract the data from fluent to plot in excel, there are over 300k points for the graph.

How do I adjust it so that I can plot just the average values instead of each mesh point value? I just want one point on the cp plot for each point on the airfoil.
