How I can plot a chart from the previos matlab file? With plot (wk) it does not work

N = 100;
axes('NextPlot', 'add'); % see "hold on"
for i = 1 : N
Ec = Ecm / (1 + q);
h1 = (h-x)/3;
h2 = 2.5*(h-d);
h3 = h/2;
H = [h1 h2 h3];
Aceff = b*min(H);
rhoeff = As1/Aceff;
Srmax1 = 3.4 * c + 0.17* qs1 / rhoeff;
Srmax2 = 1.3 * (h - x);
Srmax = min(Srmax1 , Srmax2);
epsilon1 = 0.6*sigmas/200000;
epsilon2 = (sigmas / 200000)-(0.4*fctm*(1+alpha*rhoeff)/(rhoeff*200000));
epsilon = max(epsilon1,epsilon2);
wk = Srmax*epsilon;
plot(i, wk, '+');
end
Or:
y = zeros(1, N);
for i = 1:N
...
wk = Srmax*epsilon;
y(i) = wk;
end
plot(1:N, y);
Is this "a chart"? If not, please explain in detail, what you need.
