Add title to one row of a subplot

I am using subplot and there 6*2. I want to add title for every two plots that are in the same row.

Any suggestion?

Hi Zeynab,

I understand that you want to add a single title to each row of a subplot grid that has 6 rows and 2 columns in MATLAB. Each title should span the two subplots in the same row.

I assume you are using the subplot function to create your grid

You can use the "sgtitle" function to add a title that spans the entire figure. For individual row titles, you can use the "text" function to place a title above each pair of subplots.

Here is the sample code for the same:

% Example: Create a 6x2 subplot grid
for i = 1:12
    subplot(6, 2, i);
    plot(rand(1, 10)); % Example plot
end

% Add a main title for the whole figure
sgtitle('Main Title for the Subplot Grid');

% Add titles for each row
for i = 1:6
    % Calculate position for the text
    text(0.5, 0.5, sprintf('Row %d Title', i), 'Units', 'normalized', ...
         'HorizontalAlignment', 'center', 'FontSize', 10, ...
         'Position', [0.5, 1.1, 0], 'Parent', subplot(6, 2, (i-1)*2+1));
end

Output:

Hope this helps!

Instead of using subplot, I recommend using tiledlayout which supports nested layouts and global titles.

Follow these instructions to create a centered title for each row in a tiled layout or in when using subplot.
