Visualize Cp plot between upper and lower surface of airfoil
 

Hi all,
I am fairly new to Paraview and have been learning stuffs as of now. Currently I want to visualize the Cp plot of the oscillating airfoil I'm simulating with OpenFOAM. As you can see from the image, the Points_X goes from Leading to Trailing edge for the upper surface and again goes from Leading to Trailing in the lower surface. To ensure connectivity Paraview extends a line in between as you can see from the plot. I can't seem to remove that line and also I want to visualize the upper and lower Cp curves in different color. Kindly someone guide me for it.

Thanks
