How to plot multiple graphs in one figure ?

Code 1:

clc
clear all;
close all;
xm=100;
ym=100;
x=0;
y=0;
sink.x=0.5*xm;  %location of sink on x-axis
sink.y=0.9*ym;  %location of sink on y-axis
n=100  %nodes
P=0.1 ;  %probability of cluster heads
Eo=0.5; %initial energy
ETX=50*0.000000001;  %tx energy
ERX=50*0.000000001;  %rx energy
Efs=10*0.000000000001;  %free space loss

%Data Aggregation Energy
EDA=5*0.000000001;  %compression energy
a=1;   %fraction of energy enhancment of advance nodes
rmax=3000  %maximum number of rounds
do=sqrt(Efs/Emp);  %distance do is measured
Et=0;  %variable just use below

for i=1:1:n
    S(i).xd=rand(1,1)*xm;  %generates a random no. use to randomly distibutes nodes on x axis
    XR(i)=S(i).xd;

    E(i)= S(i).E;
    A=A+talha;  
    Et=Et+E(i);  %estimating total energy of the network
    %initially there are no cluster heads only nodes
    S(i).type='N';
    figure(10)
    plot(S(i).xd,S(i).yd,'bo');
    text(S(i).xd+1,S(i).yd-0.5,num2str(i));
    title 'Node Deployment';
    xlabel 'X-Coordinate(m)';

    hold on;
