Change Y axis values in a 2D chart

Hello! Could someone tell me how I can adjust my graph number 3 to be the same as number 4? I want to get the values of the Y axis in logarithmic scale but I don't know how to do it. Thank you

Graph 3

Graph 4

%Permitividad Parte Imaginaria

Wp = 1; %Valor Correcto

gamma = 1e-3; %Valor Correcto

w1 = 0.1; %Valor Correcto

w2 = 0.1; %Valor Correcto

w3 = 10; %Valor Correcto

index = 0;

K = w1:w2:w3;

for w = 1:length(K)

index = index + 1 ;

e(index) = (gamma*Wp^2/K(w)^3+K(w)*gamma^2);

f(index) = K(w);

x(index) = f(index) ;

y(index) = real(e(index));

end

semilogx(x,y)

xlim([0 10])

ylim([-1.5 1.5])

grid

xticklabels({'0.1','1','10'})

Use loglog instead of semilogx. (And make appropriate changes to ylim.)
