polarhistogram and Shear flow distribution

Hi, I would like to use polarhistogram to represent the cutting flow of a cross section fuselage.

I do not understand how polarhistogram exactly works.

I would like to divide the circumference into N segments and give each one a precise value. Can you help me?

No one?

For example:

N=32; 
theta=linspace(0,2*pi,N+1);
x=zeros(1,N);
y=zeros(1,N);
for i=1:N
    x(i)=R_medio*cosd(rad2deg(theta(i))) ; %vettore ascisse dei boom
    y(i)=R_medio*sind(rad2deg(theta(i))) ; %vettore ordinate dei boom
end
q=linspace(0,N,N);

% polarhistogram  x-> theta   and    y-> q
