Add margin to pdf files using exportgrahics function

Hi team

I am using exportgrahics function within my loop to append figures as pdf files and merge them in one pdf file as a final outcome. All good except there are absolutely no margin at all. I want to add atleast half an inch margin on all sides (top bottom left right). I have tried different things but can't add margin to my final pdf file. Can someone please help me? I have pasted part of my codes here. You can just generate dummy plots in loop and please use exportgraphics to merge them in pne file as pdf.

If exportgraphics is not suitable function then please let me know alternative codes. I have also attached my output pdf file. Thank you.

 % FIG 1
        figure;
        plot(Date, Close, 'b-', 'LineWidth', 1, 'DisplayName', company);
        grid on;
        xlabel('Year');
        ylabel(company);
        xlim([min(Date), max(Date) + 200])
        ylim([min(Close), max(Close) * 1.1])
        ytickformat('%,.0f');
        hold on
        scatter(Px, Py, 50, 'green', 'filled', 'DisplayName', 'Positions');
        hold off
        lgd = legend;
        lgd.NumColumns = 3;
        yyaxis right;  % Secondary axis
        plot(Date_N, Close_N, 'k', 'LineWidth', 0.25, 'DisplayName', 'NIFTY-50');
        ylabel('NIFTY-50');
        xlim([min(Date_N), max(Date_N) + 200])
        ylim([min(Close_N), max(Close_N) * 1.1])
        set(lgd, 'Location', 'northwest');
        title(company, newline);
        ax = gca;
        ax.YAxis(2).Exponent = 0;
        ax.YAxis(1).Color = 'k';
        ax.YAxis(2).Color = 'k';
        ytickformat('%,.0f');
        set(gcf, 'PaperOrientation', 'landscape', 'Visible', 'off', ...
            'Position', [100, 100, 1100, 550]);
        exportgraphics(gcf, output_pdf, 'Append', true);

Hi @Amit Patel,

There are two ways to add padding to figures saved by exportgraphics:

1. Use Padding parameter. Please note that this parameter is supported in MATLAB Online only (since R2024a)

exportgraphics(gcf, 'fileName.pdf', 'Padding', 100) % Padding can be 'tight', 'figure' or a positive number

Refer to documentation: https://www.mathworks.com/help/matlab/ref/exportgraphics.html#mw_c1367a50-523c-47e6-a207-fcb49c39db87

2. You can force exportgraphics to add padding by drawing a white rectangle around it using the function annotation.

bar(1:5)
title("My Bar Chart")
annotation('rectangle',[0 0 1 1],'Color','w');
exportgraphics(gcf, 'fileName.pdf')

Documentation for annotation: https://www.mathworks.com/help/matlab/ref/annotation.html
