I have got a gridlayout with 4 panels and I would like to export specific panels to either a png, ppt or pdf. These panels have a tiledlayout and have several plots in them. Hence, I would just like to "screenshot" a specific panel and export it elsewhere.

Hi Suhas,

I understand that you want to save the plots of panels in tiledlayout seperately.

So for this you do not need to screenshot each plot, instead you can use the below feature from MATLAB to save or export plot images seperately.

Hope it helps!

exportgraphics is the function to do it.

Thanks for the reference Mario!

I managed to create a code:

function ExportButtonPushed(app, event)
             % Create a folder to store the exported images
             exportFolder = 'ExportedPanels';
             mkdir(exportFolder);
             for i = 1:4
                 try
                     % Create a temporary figure
                     tempFig = figure('Visible', 'off');
                     % Get the handle to the current panel (app.Panel_1, app.Panel_2, etc.)
                     panelHandle = app.(['Panel_' num2str(i)]);
                     % Copy the UI panel's content to the temporary figure
                     copyobj(panelHandle.Children, tempFig);
                     % Create a filename for the exported image
                     imageFileName = fullfile(exportFolder, ['Panel_' num2str(i) '.png']);
                     % Capture and export the content of the temporary figure
                     exportgraphics(tempFig, imageFileName, 'Resolution', 800, 'BackgroundColor','none', 'ContentType','vector');
                     % Close the temporary figure
                     close(tempFig);
                     % Provide feedback to the user
                     disp(['Panel ' num2str(i) ' screenshot saved as: ' imageFileName]);
                 catch exception
                     % Display an error message
                     disp(['Error capturing Panel ' num2str(i) ': ' exception.message]);
                     
                     continue; % Move on to the next panel
                 end
             end
