Here's my code, how do I plot them on the same graph? I have tried it before but it seems that it does not work.

How do I plot the original signal and it's two quantized versions in the same graph?

Read this once again:
Use hold on after the first plot() call and indeed remove subplot()

Sorry, here's my code
clc;
close all;
clear all;
echo on;
a=1;
b=3; %resolution of 3
f=1; %frequency of analog signal
fs=10; %sampling frequency
t=0:1/fs:10; %time axis
x=a*sin(t) + (a/2)*cos(2*t); %sin and cosine wave
%subplot(3,1,1);plot(t,x);grid
Nsamples=length(x); %sample number
q_out8=zeros(1,Nsamples);
q_out16=zeros(1,Nsamples);%making an array of size=number of samples
%midrise
del=2*a/(2^b); %determining the step size
Ll=-a+del/2;
Lh=a-del/2;
for i=Ll:del:Lh
for j=1:Nsamples %taking the whole sampled vector
if(((i-del/2)<x(j))&&(x(j)<(i+del/2)))
q_out8(j)=i;
q_out16(j)=i;
end
end
end
subplot(3,1,2);plot(t,x,'r',t,q_out8,'k',t,q_out16,'m');grid %plotting wave forms.
