Graphing cut line of a solution divided by a point probe value

Good morning,

Thank you in advance for any help you can provide.

I have an EM simulation in which my region of interest is a cut line. I wish to plot to plot normE of the solution divided by the value of the normE at the origin (which I have from a probe). What is the easiest way to do this? I will describe what I have already tried down below.

Thanks!

Already tried: * I defined a point probe at the origin, then changed the expression to be es.normE. Directly trying es.normE/comp1.V works, es.normE/comp1.normE gives an error. * Next, I tried to use "Join"->"Explicit" to join the cut line and probe data points. Unfortunately, I keep getting the following error: "Operation cannot be performed on data set cpt1 (Cut point 3D); - Plot: previewplot1 (Line)"
