Dimensionless wall distance and velocity in paraview

I have a 3D mesh (channel) and want to calculate the dimensionless velocity profile to compare it to the theory (wall law). Right now I create a "plot over line" and save the data to a file. Then I postprocess this data to get the dimensionless profile.
As "plot over line" creates new points and interpolates OpenFOAM data at these points, one cannot see the position of each cell in the layer. I want to check, how many cell I got in each layer and where they are, but I do not know how to extract cell values along a line including coordinates.
Is there any way to do this in paraview? Or is there another tool, e.g. provided by OpenFOAM to do the task? Can I create y+ and u+ profiles directly in paraview? I guess tau_wall is unknown and need to be provided; afterwards I would use the calculator?
