Plot pressure distribution on a section of 3d blade

My wind turbine blade has spanwise direction in z ,chordwise in x ,thicknees of airfoil in y. After simulation, I use XY plot -> pressure -> static pressure, choose monitor at z= 30% span (which i has created already with Iso-surface) to show pressure distribution over airfoil at this section.The xy plot show as the attached picture below which is very confuse for me. What should I do? Any one can help me?

So, I really need your valuable guidelines!

Sincerely yours

Perhaps you can instead create a clip surface, where you clip the foil surface from, say, 29.9 % to 30.1%. (Or maybe even 30% to 30% although I'm not sure this will work.) Good luck!
