I did step function from data that generated from Simulink. the graph is the one that I need and there's possible number for overshoot value. however the step info didnt show.

%graph
figure()
subplot(2,1,1)
plot(out.tout,out.res(:,2),'-k')
hold on
plot(out.tout,out.res(:,1),'--k')
hold on
plot(out.tout,out.res1(:,1),'--b')
hold on
plot(out.tout,out.res2(:,1),'--g')
%Step infor
stepinfo(out.tout,out.res(:,1))
stepinfo(out.tout,out.res1(:,1))
stepinfo(out.tout,out.res2(:,1))

Hi @Aidi Farhan Mohamed Sadik,
As per the code you have provided, I am assuming that "out.res" has the output data and "out.tout" has the corresponding time vector. You could try exchanging the arguments for "stepinfo" for more meaningful information.
stepinfo(out.res(:, 1), out.tout);
You can also refer to the following example for more information on the usage:

Hope this helps!
