I want to controll the number of Needle increasing and decreasing through a Toggle Button, but I can not stop it !Who can help me? Thank you!
function togglebutton1_Callback(hObject, eventdata, handles)
% hObject handle to togglebutton1 (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 togglebutton1
persistent value
value=get(hObject,'value');
if value==get(hObject,'Max')
% value_increase
for value=1:109
pause(0.2)
handles.activex1.NeedleValue=value
pause(0.2)
end
else if value==get(hObject,'Min')
value=handles.activex1.NeedleValue
% value_decrease
for value=value:-1:1
pause(0.2)
handles.activex1.NeedleValue=value
pause(0.2)
if value==1
break
end
end
end
end

Think about adding another
value=get(hObject,'value');
if value==get(hObject,'Max')
inside the loop

You need to add
guidata(hObject, handles)
to update the version of handles that is seen by other routines.
