Partitioning and putting titles in a subplot

clc; close all; clear all;

x=[0 1 2 3 6 4 5 8 5];y=[9 8 5 6 3 2 1 5 2];

subplot(4,4,1); plot(x,y);subplot(4,4,2); plot(x,y);subplot(4,4,3); plot(x,y);
subplot(4,4,4); plot(x,y);subplot(4,4,5); plot(x,y);subplot(4,4,6); plot(x,y);
subplot(4,4,7); plot(x,y);subplot(4,4,8); plot(x,y);subplot(4,4,9); plot(x,y);
subplot(4,4,10); plot(x,y);subplot(4,4,11); plot(x,y);subplot(4,4,12); plot(x,y);
subplot(4,4,13); plot(x,y);subplot(4,4,14); plot(x,y);subplot(4,4,15); plot(x,y);subplot(4,4,16); plot(x,y);

How to put partitioning as shown in the image and write title for each category ?

Hi Reji,

Please try like this:

clc; close all; clear all;

x = [0 1 2 3 6 4 5 8 5];
y = [9 8 5 6 3 2 1 5 2];

figure; % Create a new figure

for i = 1:16
    subplot(4, 4, i); % Create each subplot
    plot(x, y);
    
    % Add title to each subplot
    title(sprintf('Subplot %d', i));
    
    % Adjust subplot spacing
    if mod(i, 4) ~= 1
        ax = gca;
        ax.YAxis.Visible = 'off';
    end
    
    if i <= 12
        ax.XAxis.Visible = 'off';
    end
end

In this modified code, I've added a loop to create each subplot using subplot(4, 4, i), where i corresponds to the index of the subplot. Then, I plot the data in each subplot using plot(x, y).

To add titles to each subplot, I've used the title function with a formatted string sprintf('Subplot %d', i), where i represents the index of the subplot.

I've also adjusted the subplot spacing by hiding the y-axis labels for subplots that are not on the leftmost column (if mod(i, 4) ~= 1) and hiding the x-axis labels for subplots below the last row (if i <= 12).

Thank you. But I need partitioning lines to be visible. (Please see the red dashed line in my drawing)

If you want partioning using subplot titles then below is one method

clc; close all; clear all;

x = [0 1 2 3 6 4 5 8 5];
y = [9 8 5 6 3 2 1 5 2];

figure; % Create a new figure
k = 1;
for I = 1:16
    subplot(4, 4, I); % Create each subplot
    plot(x, y);
    
    if I <= (4) 
        % Add title to each subplot
        title(sprintf('Cat %d', k));
        k = k+1;
    elseif I > 4 & I <=8
        title('')
    elseif I > 8 & I <=12
        title(sprintf('Cat %d', k));
        k = k+1;
    else
        title('')
    end
    
end

otherwise, you can also add space between the subplots using Position property of subplot

Hi Reji,

Please do it like the following:

I know the partition lines are encroaching over the subplots : ), but I thought you yourself would be better able to adjust them according to your requirements.

clc; close all; clear all;

x = [0 1 2 3 6 4 5 8 5];
y = [9 8 5 6 3 2 1 5 2];

figure; % Create a new figure

for i = 1:16
    subplot(4, 4, i); % Create each subplot
    plot(x, y);
    
    % Add title to each subplot
    title(sprintf('Cat %d', i)); % Change "Subplot" to "Cat"
    
    % Adjust subplot spacing
    if mod(i, 4) ~= 1
        ax = gca;
        ax.YAxis.Visible = 'off';
    end
    
    if i <= 12
        ax.XAxis.Visible = 'off';
    end
    
    % Add partition lines
    if i > 4
        ax = gca;
        hold on;
        line([min(x)-0.5, min(x)-0.5], ylim, 'Color', 'r', 'LineStyle', '--', 'LineWidth', 1.5);
        hold off;
    end
    
    if i <= 12 && mod(i, 4) ~= 0
        ax = gca;
        hold on;
        line(xlim, [min(y)-2, min(y)-2], 'Color', 'r', 'LineStyle', '--', 'LineWidth', 1.5);
        hold off;
    end
end

Thank yoy for your time. I tried with the help of existing responses. But I couldn't adjust as like my hand sketch. That's why I posted it here. My requirement is well drawn in the sketch.

I need partition lines without break. Your red line is breaking at the end of a subplot.
