Hi, I have created the code to plot a data in polar coordinates as such:
theta=deg2rad(0:30:330);
r=[2.14 2.29 2.14 2.00 2.14 2.29 2.14 2.00 2.00 2.57 2.14 2.00];
polarplot(theta([1:end 1]),r([1:end 1]))
ax=gca
ax.ThetaZeroLocation='right'
ax.ThetaDir='counterclockwise'
title('RSR Value of Maximum Water Depth')
Now i want to mark all 3 minimum value of r (2.00) with a red circle, and also the maximum value with a green star. How can i do it? Thanks

theta=deg2rad(0:30:330);
r=[2.14 2.29 2.14 2.00 2.14 2.29 2.14 2.00 2.00 2.57 2.14 2.00];
polarplot(theta([1:end 1]),r([1:end 1])) ;
[val0,idx0] = min(r) ;
[val1,idx1] = max(r) ;
hold on
polarplot(theta(idx0),val0,'*r') ;
polarplot(theta(idx1),val1,'*k') ;
ax=gca ;
ax.ThetaZeroLocation='right' ;
ax.ThetaDir='counterclockwise' ;
