How can I make this graph with the "for" command?

Hi everyone. Can someone help ? How can I make this graph with the "for" command in the picture? (This question will be delete)

So, what have you done and where did you get stuck? What's the specific MATLAB Q?

I think the for command is: For a=[0, 0.2, 0.4,0.5,1,1.5 ]

But connecting it with graphs I can't get exactly 1 result in the end. And I can't plot the "undamped" , "critical" and "over" parts at all. Also I have 24 hours to do it.

Good gravy it's been forever since I did any of this. Here's a start.

ze = [0 0.2 0.4 0.5 1 1.5];
for k = 1:numel(ze)
    % 1/(s^2 + 2*ze*S + 1)
    sys = tf(1,[1 2*ze(k) 1]);
    
    stepplot(sys,25)
    hold on
end

Needs legend, etc.
