Q = .07; %(kg/s)
H = 225; %(m)
x = 0.2:10^-3:100;
Bx = 0.2:10^-3:100;%(km)
y = 0 ;%(km)
z = 0; %(km)
U = 3.1 ;%(m/s)
a = 68;
b = .894;
if x < 1 %(km)
c = 33.2;
d = .725;
f = -1.7;
else c = 44.5;
d = .516;
f = -13;
sigmay = a*x.^b;
sigmaz = c*x.^d + f;
Ba = 156;
Bb = .894;
if x < 1 %(km)
Bc = 106.6;
Bd = 1.149;
Bf = 3.3;
else Bc = 108.2;
Bd = 1.098;
Bf = 2.0;
Bsigmay = a*Bx.^b;
Bsigmaz = c*Bx.^d + f;
loglog(Bx,Bsigmay,'b')
hold on
loglog(Bx,Bsigmaz,'r')
hold on
loglog(x,sigmay)
hold on
loglog(x,sigmaz)
end
end
I am trying to plot for lines on one graph but only two lines are showing up. I have used the "hold on" command but it still only plots two lines instead of four.

Take a look at the variables you are plotting, they are duplicated. I mean Bsigmay is equal to sigmay, Bsigmaz is equal to sigmaz and Bx is equal to x. Then, your lines are overlapped and you can see just two lines.

I realized that mistake right before you answered. Thank you!!!
