how can I plot 800 samples in a percentage cicle from 0 to 100% on x axis?

[VBBV]

 % if true
    % code
 % end
S = 0:800;
Sp = S./800; % x data
Y = [...];% y data 
plot(Sp*100,Y);

Can you elaborate the question please?

I have plot a column vector of 770 values and I want to express x axis in a cicle from 0 to 100,like this .

[VBBV]

%if true
  % code
% end
S = 0:770; % change it acc to length of y data 
Sp = S/770; % x data
Y = [...];% y data 
plot(Sp*100,Y);

The x axis in the image you shared is far from circular (see polaraxes). The x axis is linear from 0 to 100.

I'm lost.

If you wanted to normalize the X values (Sp) so that they span from 0 to 100,

SpNorm = (Sp-min(Sp))./range(Sp)*100; 
plot(SpNorm, Y)
