Hi all,

First post for me on here.


I have some Excel charts, with least squares fit lines through the
data. On each chart I have a single extra data point (it's own series)
and I want to know the perpendicular distance from the line to this
point.

This is a physical distance in the real world, as my axes are both in
milimeters but to different scales.

Thanks for any help.
