How can I plot a graph on a circumference?

Hi everybody, I would like to ask you how to draw a graph on a circumference. I have the displacement on the y axes and the angle on the x axes. I would transform that plot into the circumferential plot that I draw myself and I attache it to the file in the message. Thank you all! Riccardo

Assuming the circle is centered on [0,0]:

 angle = 0:0.1:360;
 displacement = sind(6.*angle + 4);

 radius = 1;

 circx = radius*cosd(angle);
 circy = radius*sind(angle);
 plot(circx,circy); hold on;

 dispx = circx .* (radius + displacement)/radius;
 dispy = circy .* (radius + displacement)/radius;

 plot(dispx,dispy)

 axis equal
