Hello! Can someone help me to make my graph 2 look like number 1 please? I want the Y axis to be the same
1)
2)
Code
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
legend('toggle');
This statement is incomplete.

You cannot see separate lines because when you expand the y axis to cover the same range as the other plot, then the data available for this plot has too little variation in y range to show separate lines.

Your example plot has legend items such as 10^21 but I do not see which variable values that is intended to correspond to?

Here is the corrected code:
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); Wp1 = 1.0856e11;
gamma1 = 2.3518e9 ;
Wp2 = 3.4330e11;
gamma2 = 5.6747e9 ;
Wp3 = 1.0856e12;
gamma3 = 8.8952e9 ;
Wp4 = 3.4330e12;
gamma4 = 3.2292e10;
loglog(x,y1, 'b-.','linewidth',2, 'displayName', '\Gamma = 2.35*10^9')
hold on
y2 = real(e2);
loglog(x,y2, 'g-', 'linewidth',2.5,'displayName', '\Gamma = 5.6747*10^9'), grid on
y3 = real(e3);
loglog(x,y3, 'r--', 'linewidth',2,'displayName', '\Gamma = 8.8952*10^9'), grid on
y4 = real(e4);
loglog(x,y4, 'k:', 'linewidth',2,'displayName', '\Gamma = 3.2292*10^{10}'), grid on
hold off
ylim([11.55 11.705])
legend('toggle'); xlabel('$\omega$', 'interpreter', 'latex'); ylabel('$Re(\epsilon)$', 'interpreter', 'latex')

No, they expect a graph in which the y4 values start about -300
