I don't think it's possible to dynamically link the intercept value to a cell - this is just based on the fact that the UI for selecting the intercept value requires an explicit value, rather than allowing you to select a cell.
This is approximately what you need (no time here to test and get the details exact).
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
