I am Trying to Plot 3 plots onto the same graph

I am trying to combine 3 figures into the same plot. My code is as follows:

figure(1);

Vm=5.07; % Calculated on Paper

t = linspace(1,48); % Time over 48 hours

V = Vm*sin((2*pi*t)/(Ttide)); % Velocity Equation

plot(t,V)

figure(2);

E=53; %degrees

t = linspace(1,48); % Time over 48 hours

hb=Ab1*cos(((2*pi*t)/Ttide)-E); %Ocean Tide

plot(t,hb)

figure(3);

t = linspace(1,48);% Time over 48 hours

hb1=a0*cos((2*pi*t)/Ttide)%N0

plot(t,hb1)

I have tried using the "hold on" and 'hold off' functions however was not able to get it to work.

You can do this with hold on, just drop the calls to figure.

figure(1);
Vm=5.07; % Calculated on Paper 
Ttide = 1; % you didn't give us this...

t = linspace(1,48); % Time over 48 hours 
V = Vm*sin((2*pi*t)/(Ttide)); % Velocity Equation 
plot(t,V)
hold on

E=53; %degrees
t = linspace(1,48); % Time over 48 hours

Ab1 = 1.2; % you didn't give us this 

hb=Ab1*cos(((2*pi*t)/Ttide)-E); %Ocean Tide 
plot(t,hb)
 a0 = 3; % you didn't give us this
 
t = linspace(1,48);% Time over 48 hours
hb1=a0*cos((2*pi*t)/Ttide)%N0

hb1 = 1×100

3.0000 -2.9623 2.8502 -2.6665 2.4158 -2.1044 1.7402 -1.3322 0.8908 -0.4269 -0.0476 0.5209 -0.9812 1.4168 -1.8168 2.1712 -2.4710 2.7088 -2.8785 2.9759 -2.9985 2.9458 -2.8191 2.6215 -2.3582 2.0355 -1.6618 1.2462 -0.7994 0.3325

plot(t,hb1)
