Hi all,

First post for me on here, I have also posted this on the excel

charting group.

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.
