I need to plot (OMEGA1 vs Ex_nz) and (OMEGA1 vs Ex_ny) for different values of amplitude a1= 0.1, a2=0.2, a3=0.3, a4=0.4 and a5=0.5. How can I plot these on the same figure just like the image attached? Please help

hold on
plot (OMEGA1,Ex_nz,'o-r')
plot (OMEGA1,Ey_nz,'s-k')

Amplitude = rand(5, 1);
hold on
for k = 1 : numel(Amplitude) % this is an example of having different amplitudes, follow this for your example
x = linspace(0, 2*pi, 1e2);
plot(x, Amplitude(k) * sin(x));
end
