Visibility of several plot in the same axes by checkmark in GUI

I'm preparing a gui with 2-30 plots where the visibility is controlled by individual checkmark selections. The code is working perfectly when I show two plots in different axes (see gui below)
![](https://www.mathworks.com/matlabcentral/answers/uploaded_files/167576/image.jpeg)
But if I want to show the two plots in the same axes (axes1) I get this error:
Error using matlab.graphics.chart.primitive.Line/set
Invalid or deleted object.
Error in test>checkbox1_Callback (line 93)
set(handle_plot1, 'visible' , 'on')
What am I doing wrong?
Here is my code:
% --- Executes on button press in pushbutton1.
function pushbutton1_Callback(hObject, eventdata, handles)
X1=[1 2 3 4];
Y1=[-1 -2 -3 -4];
X2=[1 2 3 4];
Y2=[1 2 3 4];
set(gca, 'NextPlot', 'add'); % Equivalent to: hold('on')
handles.handle_plot1 = plot(X1,Y1,'visible','off','LineWidth',2,'color', [0 0 0],'linestyle', '--','parent',handles.axes1);
handles.handle_plot2 = plot(X2,Y2,'visible','off','LineWidth',2,'color', [1 0 0],'linestyle', '--','parent',handles.axes1);
guidata(hObject, handles);
% --- Executes on button press in checkbox1.
function checkbox1_Callback(hObject, eventdata, handles)
handle_plot1 = handles.handle_plot1
if (get(hObject,'Value')) == 1
set(handle_plot1, 'visible' , 'on')
else
set(handle_plot1, 'visible' , 'off')
end
% --- Executes on button press in checkbox2.
function checkbox2_Callback(hObject, eventdata, handles)
handle_plot2 = handles.handle_plot2
if (get(hObject,'Value')) == 1
set(handle_plot2, 'visible' , 'on')
else
set(handle_plot2, 'visible' , 'off')

Now try:
set(handles.axes1, 'NextPlot', 'add'); % Not "gca" as in my last suggestion
handles.handle_plot1 = plot(X1,Y1,'visible','off','LineWidth',2, ...
'color', [0 0 0],'linestyle', '--', 'parent', handles.axes1);
handles.handle_plot2 = plot(X2,Y2,'visible','off','LineWidth',2, ...
'color', [1 0 0],'linestyle', '--', 'parent', handles.axes1);
guidata(hObject, handles);
By the way: I use a specific function to create the 'on', 'off' dynamically:
function S = OnOffStr(D)
OffOn = {'off', 'on'};
L = (D ~= 0) + 1; % 0/FALSE => 1, anything else => 2
if length(L) == 1
S = OffOn{L}; % Reply a string
else
S = OffOn(L); % Reply a cell string
end
Then the callback looks like:
function checkbox1_Callback(hObject, eventdata, handles)
set(handles.handle_plot1, 'Visible', OnOffStr(get(hObject,'Value')));
