Graphical Analysis & Point info

[Underspec]

When printing out point information on a circle / roundness dimension (x, y, z, deviation) what is the deviation from? Is the deviation the polar distance from origin? Or deviation from the best fit circle? On the graphical analysis some arrows point out farther than others but the deviation is smaller.

Just a guess,
But I've seen similar problems.
I attribute it to the rendering of the surface on the screen.
The surface you see is sometimes not a good representation of the actual surface.
