Problems with the Y axis of my graph

Hello, please, I would like the Y axis of my graph 1 to be the same as that of graph 2

G1)

G2)

e_inf = 11.7 ;

Wp1 = 1.0856e11;

gamma1 = 2.3518e9 ;

Wp2 = 3.4330e11;

gamma2 = 5.6747e9 ;

Wp3 = 1.0856e12;

gamma3 = 8.8952e9 ;

Wp4 = 3.4330e12;

gamma4 = 3.2292e10;

w1 = 1e13;

w2 = 1e10;

w3 = 1e15;

index = 0;

K = w1:w2:w3;

% Loop is not necessary!

e1 = e_inf - ((Wp1^2)./K.^2+1i*K*gamma1);

e2 = e_inf - ((Wp2^2)./K.^2+1i*K*gamma2);

e3 = e_inf - ((Wp3^2)./K.^2+1i*K*gamma3);

e4 = e_inf - ((Wp4^2)./K.^2+1i*K*gamma4);

f=K;

x=f;

figure

y1 = real(e1);

semilogx(x,y1, 'b-','linewidth',2, 'displayName', 'e_1')

hold on

y2 = real(e2);

semilogx(x,y2, 'g-', 'linewidth',2,'displayName', 'e_2'), grid on

y3 = real(e3);

semilogx(x,y3, 'r-', 'linewidth',2,'displayName', 'e_3'), grid on

y4 = real(e4);

semilogx(x,y4, 'black-', 'linewidth',2,'displayName', 'e_4'), grid on

hold off

How does this differ from https://www.mathworks.com/matlabcentral/answers/1886627-problems-with-my-2d-graph?s_tid=srchtitle ?
