Plotting a graph in app designer using simulink

I have problem to plot a easiest graph in app designer. In simulink i made simple model of sinWave as input, and 'to workspace' named 'Sin' as output, in design view i have 2 Edit Fields, UIAxes and Button. I found on the solution on internet, but doesn't work when i try it. Here is my sintax in app designer: Assignin('base','U',app.EditField.Value); simout = sim('exmpl','StopTime', num2str(app.durationEditField.Value)); Plot(app.UIAxes,simout.Sin.Time,simout.Sin.Data); What can be a problem? I realy don't understand why it doesn't work.

Use 'output' instead of 'to workspace'.

function startupFcn(app)
            h = load_system('test');
            %test
        end

    % Button pushed function: runButton
    function runButtonPushed(app, event)
        simout = sim('test');
        assignin("base","simout",simout);
        plot(app.UIAxes,simout.tout,simout.yout{1}.Values.Data);
    end
end

Here is the result:

Thank you very much on your help. Now when i tried this, yout is empty, and i can't plot a graph, tout is there, and i can access it. Do you know ehat can be a problem? And why is yout empty?

In different versions of MATLAB, the name yout may be different. Send simout to work space using assignin and then check the exact name of your data.

Thank you again on your answer, it was very helpful tu me. Atribute actualy is named yout and was empty matric, and now i figured out why, but it steel doesn't work. I will probably find out what is problem, after your help all the time.
