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:

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.
