Hello everyone, I want to develop a GUI with which I can change the title, X-Axis and Y-Axis labelling of the figure named 'trial_for_graphic'. I want to change the title, xlabel and the ylabel of the same figure. However, when I run the code (given below),it generates a different window figure for every option. So, I cannot change the title, xlabel and ylabel in the same figure window. Can anyone please tell me as to how I can change the three parameters in the same figure window ?

val = get(handles.popupmenu_select_parameter,'Value');

string = get(handles.popupmenu_select_parameter,'string');

string2 = get(handles.edit1,'string');

open('trial_for_graphic.fig')

switch val

      case 2 
        title(string2)
     case 3
       xlabel(string2)
    case 4
        ylabel(string2)

end

before entering the switch case you open the figure window like this;

figure; switch val

      case 2
        hold on 
        title(string2)
     case 3
        hold on
       xlabel(string2)
    case 4
        hold on
        ylabel(string2)
end

Well, what I want to do is that I want to change the parameters of the graph, one by one. So, when I change the title by choosing 'title' from the GUI popupmenu, the title of the trail_for_gui.fig is changed, in the figure1 window. When I now select the xlabel option from GUI popupmenu, it should change the xlabel of trial_for_figure.fig in the same windoe (i.e figure1). However, when I run my code, it opens another window (figure2) and then changes the xlabel. So, I have two windows of same graph, one with its title changed and the other with its xlabel changed.

i have created some example gui check this.

% --- Executes on button press in pushbutton1. function pushbutton1_Callback(hObject, eventdata, handles) % hObject handle to pushbutton1 (see GCBO) % eventdata reserved - to be defined in a future version of MATLAB % handles structure with handles and user data (see GUIDATA) hold on h=title('hhhh');

% --- Executes on button press in pushbutton2. function pushbutton2_Callback(hObject, eventdata, handles) % hObject handle to pushbutton2 (see GCBO) % eventdata reserved - to be defined in a future version of MATLAB % handles structure with handles and user data (see GUIDATA) hold on xlabel('hhhhhhhghgf');

% --- Executes on button press in pushbutton3. function pushbutton3_Callback(hObject, eventdata, handles) % hObject handle to pushbutton3 (see GCBO) % eventdata reserved - to be defined in a future version of MATLAB % handles structure with handles and user data (see GUIDATA) hold on ylabel('hhhhhhhghgfgjjg');
