So just as the title says I want to know what the data means. By this I mean the table that appears when you go to Filters \> Integrate Variables.  
Could someone explain to me what these mean and the units.  
The “Drag” variable in the photo is the “Calculator” filter and “Normals\_Y” as the scalar value.

Sorry, but I don’t know what a pipeline browser is. So could you tell me what that is, and how to know mine.

Here is the final result for me. I wasn’t able to properly follow step 8 because there was no option for “Vector” in Scale Mode, or an option called “Vectors”.

Ok, what is your question then ?

Share what you are doing and what is not working more clearly.

To get that point what I did is put my model (stl) into paraview. Then I Extracted Surface from the Filters menu, also generated surface normals, and then added calculator for “Normals\_Y”. After that I went to filters and chose Integrate Variables to show a table.

My question is  
What do the different variables on the table mean?  
So for example, the Column labeled “Normals”, I want to know what that means and what units its in.

PointID: ID of the point, unique for each point  
Drag: You computed it in the Calculator filter  
Normals: A unit vector orthogonal to the surface of the cells surrounding the point ([Normal (geometry) - Wikipedia](https://en.wikipedia.org/wiki/Normal_(geometry)))  
Points: 3D coordinates of the points

In ParaView, nothing has units, it’s always relative to your data or without intrinsic unit.

Thank you very much. That helped out a lot.
