How to plot multiple graphs on the same figure using a loop?

Hi, I have attached the code im working on below. In the when the first for loop executes, the if statement at the bottom executes and prints a graph of how many loops the code has completed against how many cells are on the screen in a new figure. What I want to have is, a larger loop that will print the graph thats plotted in the if statement on the same figure 10 times to show 10 different runs of the code. This would require restarting the code when the first for loop reaches i=100. I cant get any implementation of this to work. Any help would be appreciated.

size_of_game = 100;
mylife = round(rand(size_of_game,size_of_game));

  gen = gen + 1;
  l(i) = gen;
  generation = [l];

  newlife = mylife;
  for ii = 1:size_of_game
    si = ii-1;
    ei = ii+1;
    veci = si:ei;
    veci(veci==0)=size_of_game;
    veci(veci==size_of_game+1)=1;
    for jj = 1:size_of_game
      %%%This is overlap from each side
      sj = jj-1;
      ej = jj+1;
      vecj = sj:ej;
      vecj(vecj==0)=size_of_game;

Maybe something like this (create one figure with both the life grid and the number of live cells over time):

clear all
close all
clc

size_of_game = 100;

n_runs = 10;
n_gens = 100;
noOfLiveCells = NaN(n_runs,n_gens);

figure()
life_axes = subplot(1,2,1);
n_cells_axes = subplot(1,2,2);
hold on
grid minor
grid on

axes(life_axes);

for j = 1:n_runs
    
    %%%Random Seed
    mylife = round(rand(size_of_game,size_of_game));
    
    for i = 1:n_gens
        spy(mylife);
        %Propagate
        newlife = mylife;
        for ii = 1:size_of_game
            si = ii-1;
            ei = ii+1;
            veci = si:ei;
            veci(veci==0)=size_of_game;
            veci(veci==size_of_game+1)=1;
            for jj = 1:size_of_game
                %%%This is overlap from each side
                sj = jj-1;
                ej = jj+1;
                vecj = sj:ej;
                vecj(vecj==0)=size_of_game;
                vecj(vecj==size_of_game+1)=1;
                num_neighbors = sum(sum(mylife(veci,vecj)))-mylife(ii,jj);
                if mylife(ii,jj)
                    %Any live cell with fewer than two live neighbours dies, as if caused by under-population.
                    if num_neighbors < 2 %1 - 2, %2 - 3 , %3 - 2
                        newlife(ii,jj) = 0;
                    end
                    %Any live cell with two or three live neighbours lives on to the next generation.
                    
                    %Any live cell with more than three live neighbours dies, as if by overcrowding.
                    if num_neighbors > 3 %1 - 3, %2 - 4, %3 - 3
                        newlife(ii,jj) = 0;
                    end
                else
                    %Any dead cell with exactly three live neighbours becomes a live cell, as if by reproduction.
                    if num_neighbors == 3 %1 - 3, %2 - 3, %3 - 2

                    end
                end
            end
        end
        drawnow
        mylife = newlife;
        livecell = 1;
        %Number of live still lifes counter
        noOfLiveCells(j,i) = nnz(conv2(mylife,livecell,'valid'));
    end
    
    % plot after the "generations" loop:
    plot(n_cells_axes,1:n_gens,noOfLiveCells(j,:));
