Accepted answer

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

MATLAB might be more appropriate if you want to control the line styles. See Specifying Line Style.

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.)
