I had previously asked a question here, how to get the real coordinates of the points in the following figure by Mathematica:
Two answers were provided, which by using them, I could get almost all points, with a few exceptions. Now, I need to get the real coordinates of the remaining ones. I'd like to know how can this be done manually for one arbitrary point in the above figure? In other words, if by using "Get Coordinates", I get the coordinates of a point, how can I convert this to real coordinates?
P.S. $2$, $8$, and $16$, on the $x$-axis above, are just labels (see also the answer in the above link).
