How to plot multiple graphs in one figure ?

 I have two codes. Each code has four graphs. I want to plot two graphs in one figure. For example: Dead nodes vs Round graph of two should be in one figure. In the same way other graphs also. I tried hold on function but still not getting. How to merge the two codes in order to get the graphs ?

Code 1:

close all;
xm=100;
ym=100;
x=0;
y=0;
sink.x=0.5*xm;  %location of sink on x-axis

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

    S(i).G=0; %node is elegible to become cluster head

    S(i).E=Eo*(1+talha);
    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));

    hold on;

> I want to plot two graphs in one figure

Options are

• subplot
• tiledlayout with nexttile - preferred, starting in R2019b

subplot(m,n,i) creates an axes in the i^th position of an m-by-n grid.

tiledlayout(m,n) creates an m-by-n grid upon which axes can be added using nexttile.

See documentation links for details.

Benefits to using tiledlayout

The following features are great improvements available in tiledlayout.

1. Flexible grid sizes (TileArrangment property)
2. Control spacing (TileSpacing and Padding properties, Community Highlight)
3. Row-wise or column-wise order of axes (TileIndexing property, Community Highlight)
4. Global labels such as a title, subtitle, xlabel and ylabel (labels properties)
5. Global legends, starting in R2020b (legend layout property, documentation example, more demos)
6. Global colorbars, starting in R2020b (colorbar layout property, documentation example, demo)
7. Specify the span of an axes within the grid using nexttile(span)

Demo

 

 

tcl = tiledlayout(2,3,'TileSpacing','compact');

nexttile
plot(magic(5))
axis tight
