Could someone help me to access to the value of the radius automatically plotted in any rose diagram? I have to say that I use Matlab 14b. Say, having the following code, how can I get the value 40?
load sunspot.dat
theta = sunspot(:,2);
figure (222)
rose(theta,12)

Ask rose for two outputs. You can then plot it with polar.
The Code —
load sunspot.dat
theta = sunspot(:,2);
[t_out, r_out] = rose(theta,12);
[r_max, idx] = max(r_out) % Maximum Radius & Index
t_max = t_out(idx)*180/pi % Corresponding Angle
figure (222)
polar(t_out, r_out)
r_max =
38
idx =
30
t_max =
210

My pleasure.
The get function will work regardless of the version you are using. I thought R2014b (that introduced the new ‘Handle Graphics 2’) also introduced the structure syntax. My apologies.
