A function plotting issue with fplot

I want to plot the function vs . I can get the result using fplot, however the x-range () is not

correct. My code is:

v1 = -2.63; v2 = -2.38; gamma=1;
T=[0:0.01:5];
k=pi/2;
l=-k;
w=-2*cos(k);
w1=-2*cos(l);
delta2 = @(T) v2-w+(gamma.*abs(T).^2);
delta1 = @(T) v1-w+gamma*abs(T).^2.*abs(delta2(T)-exp(1i.*k)).^2;
delta21 = @(T) v1-w1+(gamma.*abs(T).^2);
delta11 = @(T) v2-w1+gamma*abs(T).^2.*abs(delta21(T)-exp(1i.*l)).^2;
 fplot(@(T) abs((exp(i*k)-exp(-i*k))/(1+(delta2(T)-exp(i*k)).*(exp(i*k)-delta1(T))))^2,[0,5],'g')
 hold on
 fplot(@(T) abs((exp(i*l)-exp(-i*l))/(1+(delta21(T)-exp(i*l)).*(exp(i*l)-delta11(T))))^2,[0,5],'r')
 hold off

The output is alright but the x-axis range seems not correct. The correct figure (ignoring the middle dotted black curve) should look like

What I get is the following

I tried various ways but failed to fix the x-axis issue, what is the problem here?. Any help is highly appreciated. Thanks.

John - is the output correct? If it is, what is the x-axis issue? Why do you think it should look like the first figure?

Fixed it. It was an error in writing. Thanks.
