Plotting Displacement Slope Error Along a Cut Edge

I am having a hard time plotting the slope error along a 3D-cut edge data set and coming up with a subsequent standard deviation of this error. I would like to plot the slope error of the net vertical displacement along this line which runs along the y-axis from -200mm to 200mm. I think that I can plot the slope by using the expression:
abs((z-Zg)/(Yg))
However, I can't come up with a way to create a plot of slope error. In excel, I get a value of slope error for each data point with the expression (z_(n+1) - z_n)/(Y_(n+1)-Y_n)... where z is the vertical displacement. Being able to plot slope error in Comsol would be a huge help to me but I'm not sure how to go about it. I do know that once I have this plot I can use a line integration to evaluate the standard deviation.
Any help or a point in the right direction would be greatly appreciated. Thank you!
