Hi,
I have small example that may helps you.
You should design a GUI as shown in picture below
And then save your file.
Unfortunatelly, GUIDE does not automatically create SelectionChangeFcn callback for you.
You can create it by right-click uibuttongroup1 and select SelectionChangeFcn from the View Callbacks context menu item.
Then, write this code below in uipanel1_SelectionChangeFcn
switch get(eventdata.NewValue,'tag')
case 'radiobutton1'
set(handles.uipanel2,'visible','off');
case 'radiobutton2'
set(handles.uipanel2,'visible','on');
case 'radiobutton3'
set(handles.uipanel2,'visible','off');
end
Don't forget to set the uibuttongroup2 unvisible at openingfcn.
set(handles.uipanel2,'visible','off');
Now, run the code.
Try to select radiobutton2, and uibuttongroup2 will appears.
