Radiobutton control

I have six radio buttons and a pushbutton in my gui .I want depending on which radiobuttons are pressed by the user the gui to be able to plot different histograms.And if no radiobutton is pressed a message to appear and warn the user tha he should push a radio button .My code is this :

 % --- Executes on button press in radiobutton12.
  function radiobutton12_Callback(hObject, eventdata, handles)
  % hObject    handle to radiobutton12 (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 radiobutton12

handles.radiobutton12=get(hObject,'Value');

    guidata(hObject,handles)      
...
and other 5 radiobuttons Callbacks ....and then the pushbutton :

% --- Executes on button press in pushbutton19.
function pushbutton19_Callback(hObject, eventdata, handles)
% hObject    handle to pushbutton19 (see GCBO)
% eventdata  reserved - to be defined in a future version of MATLAB
% handles    structure with handles and user data (see GUIDATA)

if (get(handles.radiobutton12 ,'Value') == get(handles.radiobutton12 ,'Min'))&& (get(handles.radiobutton13 ,'Value') == get(handles.radiobutton13 ,'Min'))&& (get(handles.radiobutton14 ,'Value') == get(handles.radiobutton14 ,'Min'))&& (get(handles.radiobutton15 ,'Value') == get(handles.radiobutton15 ,'Min'))&& (get(handles.radiobutton16 ,'Value') == get(handles.radiobutton16 ,'Min'))&& (get(handles.radiobutton17 ,'Value') == get(handles.radiobutton17 ,'Min'))

      msgbox('You should select at least one radiobutton in order to evaluate the condition of the patient and see the  histograms','Patient Progress','warn')
      return

else

      figure('Name','b value histograms ','NumberTitle','off'); 
      kan=max(max(handles.hist),max(handles.hist1));
      xlim([0 255])
      plot(handles.hist/kan,'b');
      h = legend('Before Treatment','Location','NorthEast');
      set(h,'Interpreter','none')
      xlabel('b-value Signal_Density');
      ylabel('Volume Fraction of Tumor');
      hold on 

      if  handles.radiobutton12==1;
      plot(handles.hist1/kan,'r');
      h= legend(h,'After Treatment','Location','NorthEast');
      set(h,'Interpreter','none')
      end
...and it continues for each radiobutton press.

when i press the push button without any pressed radiobutton the warning message appears but when i push a radioutton matalb gives me this error ??? Error using ==> get There is no 'Value' property in the 'figure' class.

Error in ==> DWI_Liver_Analyzer>pushbutton19_Callback at 2388 if (get(handles.radiobutton12 ,'Value') == get(handles.radiobutton12 ,'Min'))&& (get(handles.radiobutton13 ,'Value') == get(handles.radiobutton13 ,'Min'))&& (get(handles.radiobutton14 ,'Value') == ge

What should i change can anybody help me ?

Thanks in advance .

Run:

dbstop if error

And then run your program as you were. Reproduce the error and the debugger will stop on line 2388. On this line inspect each variable and each call to |get()}. It should be apparent at this point that one of the handles is actually to a figure trying to get its 'Value' property which it doesn't have.

Sean de Wolski , thank for your time but i dont think that that s the problem ,the beggining of the code in the i do this for all the radiobuttons,12,13 ,14,15,16,17 :

   % --- Executes on button press in radiobutton12.
    function radiobutton12_Callback(hObject, eventdata, handles)
    % hObject    handle to radiobutton12 (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 radiobutton12

handles.radiobutton12=get(hObject,'Value');

      guidata(hObject,handles)

how can a handle is going to a figure ?perhaps isnt this the right way to write the code .

the thing i want is if no radiobutton is pressed to show a message ,i know its quite simple but .....i am stuck!

Thanks again .....if you have other ideas please help !!!!!

Because this callback must be getting called by the figure.

Look at the figure's callbacks in ther GUIDE inspector.
