Hey Alden,

I understand that you want to use button to toggle the visibility (open or close) of scope in a Simulink model.

You can use a button to open or close the scope window by following the below steps:

1. Add a ‘Push Button’ block from the Simulink Library Browser (Simulink/Dashboard).
2. Right click the “Push Button” block and click properties.
3. In the Porperties console, click on the callback tab.
4. Configure a callback for the Button Block under “OpneFcn” Callback using the following code snippet:

%Callback for Button 
if strcmp(get_param(uModel_name/Scopet, tOpeno), noni) %check if the button is on
    set_param(‘Model_name/Scope’, ‘Open’, ‘off’); 
else 
    set_param(‘Model_name/Scope’ , ‘Open’, ‘on’); 
end 

Using this you can achieve the desired functionality. Enclosed is a screenshot of the attached model, which you can use for your reference:

Hope this helps.
