How do I name each line in polar plot differently
This doesnt work
angle = 0:0.1745:2*pi;
Spl49 = [81.97499084 81.65412903 81.59463501 81.40548706 81.53025818 81.44108582 81.33396149 81.41963959 81.23446655 81.60978699 81.15054321 81.46079254 81.90848541 81.74275208 82.02006531 82.06681824 82.30259705 82.13386536 82.34589386 82.50636292 82.38869476 82.81261444 82.83797455 82.99743652 82.84294891 82.85511017 82.91734314 82.53729248 82.9249649 82.59764862 82.8104248 82.43968201 82.31278229 82.16514587 82.13431549 82.08069611 81.97499084];

polarplot(angle,Spl49)
legend("49Hz");

hold on
polarplot(angle,Spl62)
legend("62.5Hz");
% theta = 0:0.01:2*pi;
% rho = sin(2*theta).*cos(2*theta);
% polarplot(theta,rho)
I just get this

Call legend once after both lines are added and include a name for each line.
legend(["49Hz","62.5Hz"]);
Alternatively, assign a DisplayName to each object when the object is created and then call legend without the object names,
polarplot(__,'DisplayName', '49Hz')
hold on
polarplot(__,'DisplayName', '62.5Hz')
legend()
