well, I'll try to re-explain
the data was firstly an x/y cartesian coordinates, which I transform to
polar coordinates ( theta, radius). here is it in the file.
moyen_cylindre.txt
<http://octave.1599824.n4.nabble.com/file/t373159/moyen_cylindre.txt>
for the polar representation of the data, here is the code:
load('moyen_cylindre.txt')
theta = moyen_cylindre(:,1);
radius = moyen_cylindre(:,2);
polar(theta,radius,'+')
for the other figure in which I want to represent the deviation, here is the
code:
radius1 = abs(radius);
deviation = radius-10; % 10 is the nominal radius
plot(theta,deviation,'+')
the problem is, I can't see how to do a fitting for the curve (as it is in a
total mess and it looks like two superposed curves)
what I want is to have a continuous plot for the deviation
I hope that is clear
