How to create a subplot of multiple plots within a for loop?

I am generating a table using a for loop, and using that table to create three plots. How do I convert them into a layout such that first two figures are on top, and the third is at the bottom? Thanks. Here's my MWE

% Generating my table first
for j = 1:4
    Table = [];
    for i = 1:7
        M = array2table(randi([55 100],6,1), 'VariableNames', strcat('X_', string(i)), 'RowNames',{'A', 'B', 'C', 'D', 'E', 'F'});
        
        % Combining each column table
        Table = [Table, M];
    end
    disp(Table)
    % --- MY FIGURES SHOULD BE PLACED HERE WITH TWO SIDE-BY-SIDE ON TOP AND ONE AT THE
    % BOTTOM.

% Figure 1
% --------------------------------------------------------------------------------
    figure1 = figure;
    x = 1:7;                           % Set x axis values
    y = [Table{{'A'},:};
        Table{{'C'},:}];                                        % Set y axis values
    
    a1 = bar(x,y);                                                       % Generate figure
    
    xlabel('Years');                                                     % Add x label
    ylabel('(in billion $)');                                            % Add y label
    title('Profit as a share of revenue across years');                  % Add plot title
    
    set(a1, {'DisplayName'}, {'Profits','Revenue'}');                     % Add display names to legends
    legend('Location','northwest' );                                      % Change location of legends
    legend boxoff                                                       % Remove the box around legends
    
    box off                                                             % Remove the top and right splines from the plot
    % Figure 2

    figure2 = figure;
    y = [Table{{'B'},:};    
     Table{{'D'},:}];                                           % Set y axis values

b1 = bar(x,y, 'stacked');
hold on
b2 = bar(x,Table{{'A'},:},0.55,'FaceColor',[0 0.7 0.7]);
hold on 
b3 = bar(x,-1*Table{{'F'},:},0.1,'FaceColor',[0.4 0.1 0.7]);
hold off
hold off                                                            

xlabel('Years')                                                     % Add x label
ylabel('(in billion $)')
title('Present Value of Profits and Discount Factor')                           % Add plot title

set(b1, {'DisplayName'}, {'Profits', 'Revenue'}')                     % Add display names to legends
set(b2, {'DisplayName'}, {'Profits (in PV terms)'}')

@Alston D'Souza,

This code generates 2 plots above and one plot below:

>> x=1:10;
>> figure;
>> subplot(2,2,1); plot(x,x,'rx-');
>> subplot(2,2,2); plot(x,x,'go-');
>> subplot(2,1,2); plot(x,x,'bs-');

A screenshot is below.

Thanks, I tried running this today. Although it works perfectly when executed separately, the subplots dont work when generated within the loop.

Can you please incorprate your code within the MWE code I provided?

Thank you so much

Use nexttile(span) along with tiledlayout

fig = figure(); 
tlo = tiledlayout(2,2); 
nexttile()
plot(rand(5,5)); 
nexttile()
plot(rand(5,5))
nexttile([1,2]) % <-- spans a 1x2 section of the 2x2 layout
plot(rand(5,5))

@Alston D'Souza, William's answer is a minimal working example. By asking him to rework the example into your code, you're really asking him to do the work for you. It's no longer an example in that case.

It would be better to show us how you implemented his example into your work, describe the (new) problem, and let us help you fix it. That way you learn and you do the work.

[Alston D'Souza]

Thanks Adam. I tried tinkering a little bit, and it works. Here is my final code.

        % Combining each column table
        Table = [Table, M];
    end
    disp(Table)

Nicely done.

Thank you @Adam Danz.

@Alston D'Souza, The atattahced code makes one figure on each pass through the main loop of your code: four passes, four figures. Each figure has two plots on top and one on the bottom, as you requested. You may want to adjust the legend positions or the axes, so that the legends do not get in the way of the axes. Screenshot of figure 1 is below; the other 3 figs are similar.
