Plotting subplots in one figure, with shared axes and labels

This segment of code is supposed to plot some plots in (9 subplots for each figure) arrangment. However, I am trying to make a shared y-axis for each row and a shared x-axis for each column and keep only one axis label on each axis. This code works perfectly fine for the first figure that is plotted, however, for the next figures it does not apply the same formatting on them.If anyone can help in resolving this.

the figure "i1" shows what I am getting for the first figure and what I want, and the figure "i2" shows what I am getting for the other figures. we want to keep the formatting of all figers as figure one.

attached is a sample of the data being plotted.

This is the segment of code used:

% ii represents the number of plots that we have to plot. In this case ii=86
numFigures = ceil(ii / 9);
             

   % Check if a new figure is needed
                if mod(ii - 1, 9) == 0
                    % Create a new figure
                    hFig = figure('Name', ['Combined Plots Figure ', num2str(numFigures)], 'NumberTitle', 'off');
                    numFigures = numFigures + 1;
                end

                % Plot each set of 9 plots together
                subplot(3, 3, mod(ii - 1, 9) + 1, 'Parent', hFig);
                hold on;

                % Plot data
                plot(xss, updatedy, '-x', 'color', "#000000", 'LineWidth', 1)

                % Adjust axes and labels for all figures
                if mod(ii - 1, 3) == 0
                    ylabel('Height (km)');
                else
                    set(gca, 'YTickLabel', []);
                end

                if ii > 6
                    xlabel('Ne (el/m^3)');
                else
                    set(gca, 'XTickLabel', []);
                end

                ylim([100 800])
                grid on
                hold off

We can not run your code nor infer anything from it as it is missing data and context.

Nor is it clear what the expected output is.

Please share the data, context and what the expected output is (an example should suffice).

Additionally -

Are you running a for loop to plot the figures? And why not add the labels after plotting everything?

@Salma fathi, I see that you have updated the question, however you have not answered my questions.

Are you running a for loop?

What is ii? If it is 86, then is the output supposed to be 9 figures with 9 subplots and 1 figure with 5 subplots?

[Salma fathi]

Thank you for your comment.

Yes I am using a for loop to plot the output, each iteration will result in a subplot. ii is the number of iterations that we have, i.e. the number of subplots that we have. And you are correct the output would be 9 figures with 9 subplots and 1 figure with 5 subplots.

I am trying to have a shared y-axis for each row of subplots in a figure, and a shared x-axis for each column of subplots.

A better option would be to use tiledlayout here as you can make shared axis labels and titles -

This is a general idea, you can make changes to it as you like.

load('data.mat')

ii=86;

for k=1:floor(ii/9)
    
    hFig = figure(k);
    
    t = tiledlayout(3, 3, 'Parent', hFig);
    for n=1:9
        nexttile
        plot(xss, updatedy, '-x', 'color', "#000000", 'LineWidth', 1)
        if  ~ismember(n, [1 4 7])
            yticks([]);
        end
        if ~ismember(n, [7 8 9])
            xticks([])
        end
    end
    title(t, sprintf('Figure %d', k))
    ylabel(t, 'Height (km)');
    xlabel(t, 'Ne (el/m^3)');
end
