How to handle radiobutton in radiobutton group panel...

Hi, Community....

I have a question about radiobutton group.

<<< ----- This is my ButtonGroup

So i have tried with this code to handle a plot of the selected component based on radiobutton clicked in my radiobutton group panel :

function matikan_radio_button(off)
set(off, 'Value', 0)

% --- Executes on button press in kompx.
function kompx_Callback(hObject, eventdata, handles)
% hObject    handle to kompx (see GCBO)
% eventdata  reserved - to be defined in a future version of MATLAB
% handles    structure with handles and user data (see GUIDATA)

% Hint: get(hObject,'Value') returns toggle state of kompx
off = [handles.komph, handles.kompz, handles.kompf, handles.kompy];
matikan_radio_button(off)
pilih = 1; 
pilih = handles.pilih;
guidata(hObject, handles);
% --- Executes on button press in kompy.
function kompy_Callback(hObject, eventdata, handles)
% hObject    handle to kompy (see GCBO)

% Hint: get(hObject,'Value') returns toggle state of kompy
off = [handles.komph, handles.kompz, handles.kompx, handles.kompf];
matikan_radio_button(off);
pilih = 2; 
pilih = handles.pilih;
guidata(hObject, handles);

            case 2 %This should to handle kompy radio button tag name
                .....
         end
 end

I tried with that code, but my the axes didnt do plotting based on my selected radio button in radio button group..... For example, if i choose radiobutton with kompx tag name , then this should handle

switch  pilihan
             case 1....

and plot based on the data x versus time at the code. However it doesnt work.

So, everyone, would you lend me a hand to solve this problem? Iam very grateful if someone can solve my problem here....

Thank you very much everyone... /.\ /.\ /.\

Tyann - I think the assignments in each radio button callback is incorrect

pilih = 3; 
pilih = handles.pilih;
guidata(hObject, handles);

Don't you want to assign as

handles.pilih = 3;
guidata(hObject, handles);

instead? Or do you even need this? If you just want to know which radio button is enabled, then update your switch statement from

switch  pilihan
             case 1 %This should to handle kompx radio button tag name

to an if/elseif as

if get(handles.kompx, 'Value')
    % stuff
elseif get(handles.kompy, 'Value')
    % etc.
end

Since your radio buttons are within a radio button group, then only one will be enabled at any one time. And you know if it is enabled because Value is 1.

Yes, Sir... I am just so curious, whether my button in the buttongroup channel had been accessed by that code or not. If it was not accessed, so how to access it? Is it need like parent, that is uibuttongroup1 when we call it by using handles function or not.... for example :

get(handles.uibuttongroup1.kompy, 'Value') , im just so confused.... I created GUI from Guide, though... And each button in that panel is also have a weird behavior. If i put a value (from properties) other than 0 in each button, then the buttons is only appear 1 button instead of 5 buttons....

[Geoff Hayes]

@Tyann Hardyn - use the MATLAB debugger to place a breakpoint in the radio button callback. Then run your GUI and select the radio button. If the callback is called, then the debugger will break at that breakpoint.

@Geoff Hayes

Thats Great, Sir. Your code is work on me. So the solution is just using IF instead of switch and case?? But why? In my matlab manual book, the radio button should work well with switch and case... Hmmm.

Here is the result. Now I can plot according to the radiobutton i switch in my gui program. Thank you very much, Sir.

Ah, one more question, Sir... Iam just curious, how to handle plot just when i select a radio button after my pushbutton was pressed before? I mean, how to handle the guidata just by using selecting radio button on it?

[Geoff Hayes]

@Tyann Hardyn - I think your code was incorrect. Look how you were using the switch statement:

pilihan = get(handles.pilih);
switch  pilihan

and now look how you were assigning pilih

pilih = 4; 
pilih = handles.pilih;
guidata(hObject, handles);

You were never assigning a value to handles.pilih. Your code should have been

handles.pilih = 4;
guidata(hObject, handles);

As for you last question, I'm not sure I understand. Please clarify what you mean by how to handle plot just when i select a radio button after my pushbutton was pressed before?. Do you want to dynamically update the plot as the user chooses a new radio button?

[Tyann Hardyn]

@Geoff Hayes

Do you want to dynamically update the plot as the user chooses a new radio button?

Correct, SIr. Yes, that what i meant. When i press a button (Call Data Button) to get a data (lets say Magnet Data), it will plot as A versus Time because the RadioButtonA was selected before, then, if i select another RadioButton, i.e RadioButtonB, so it would plot B versus Time automatically, where A and B is a data series in Magnet Data which re get by pressing Call Data Button before

Could it possible, Sir? Thankyou very much /.\
