H insafba,
You should learn how to describe problems accurately which is a crucial
ability to do engeneering/scientific work.

I have some data related to points of the perimeter of a circle (which is
not perfect and have some deviations) that I collected from a 3D scan of a
part.
"some data": x/y coordinates in a cartesian system? r(phi)? Equally
spaced in time?
When I represent the data by polar commend, I have (as mentioned
before) a circle. BUT, when I want to plot the deviation (the nominal radius
- the actual data), I have a total mess representation as shown in the next
figure

Without showing the code which led to both plots it's very hard to guess
what you are doing. One shows a polar plot, the other a cartesian plot
I can just guess that you are looking for something like "unwrap"
I hope that all is clear.
No, it isn't
