Problems with my 2D graph
显示 更早的评论
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');

The code you posted (which you should format as code, by the way) creates graph 2.
If you really meant that you want your graph to look like graph 1, then explain what, specifically, you like about graph 1 and want to replicate in your graph. Is it the line styles (dashed vs. solid)? The legend with no box? The blue axes? The two x axes? The actual shape of the lines, of course, will not match because of the data that you are plotting.
BTW - to format your code, edit the question, select all of the code, and press the left hand button in the CODE section of the toolbar above.

The "incomplete" is due to the ":" (colon) at the end of the last line that needs to be ";" (semi-colon) instead.
With minor changes:
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
L = legend('toggle');
L.Box = 'off';
L.Location = 'southeast';

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
