This is a plot of a step response of second order system, you can use step command in a for loop, varying the damping coefficient sigma from 0 to 1
hold on;
sigma=.5;
for k=1:5
w0=1;
sigma=sigma+.1;
N=[w0];
D=[1 2*sigma*w0 w0^2]
step(N,D)
end
grid

you can get the same figure in simulink, by simulating 5 ore more second order transfer function with differents damping coefficient sigma, and use one scope and one multiplexer

What do you mean by they are in negative region, and show correctly the image you want to make.

It appears that is a frequency response, what your graph is supposed to represent?

You can't just draw this plot, you must provide the frequency response

You put it together yourself, calculating where all the lines should go.
There is no built-in plot of that style that I know of in MATLAB (but it is possible it exists in a toolbox somewhere or in Simulink somewhere and I just have not run across it yet.)

Pat: Are you asking us to identify the function that has been plotted? That might be difficult to do.
