Exporting UIFigure using Matlab 2020a

Hello all,

I have created an app which displays some data upon clicking some buttons. I want to save the UIFigure (with all the data) as a pdf or a jpg file. I know that for Matlab 2020b and onwards, there is the 'exportapp'. However, I am using Matlab 2020a and was wondering what alternatives exist to save the app UI as a pdf or an image. I tried using the following command: exportgraphics('app.UIFigure','screenshot.jpg') but this gives a blank jpg image.

Thank you for your time.

Kind Regards,

Abhishek

Hi Abhishek,

I faced a similar issue in MATLAB R2020a but I observed that it was working fine with MATLAB R2020b onwards. So, a possible fix could be to try upgrading MATLAB to a newer version. There is also a workaround which I found, instead of passing 'app.UIFigure', I tried passing a component inside it which in my case was the axes object 'app.UIAxes' and it was working fine with it.

        % Button pushed function: Button
        function ButtonPushed(app, event)
            % Plot some data
            plot(app.UIAxes, rand(1,10));
            app.Label.Text = 'Data Plotted!';
        end

        % Button pushed function: SaveImageButton
        function SaveImageButtonPushed(app, event)
            
            figure(app.UIFigure);
            exportgraphics(app.UIAxes,'screenshot.jpg') %Works Fine
        end

Hope it helps!
