I have from 2-30 plots where I want to control the visibility by checkmark selection in a GUI (Guide). But I can't get it to work. Please help.

Here my code with two simple plots:

% --- 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]
handles.handle_plot1 = plot(X1,Y1);
handles.handle_plot2 = plot(X2,Y2);
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')
   end

But I get this error:

Error using matlab.graphics.chart.primitive.Line/set
Invalid or deleted object.
Error in test>checkbox1_Callback (line 91)
       set(handle_plot1, 'visible' , 'on')

What am I doing wrong?

在 MATLAB Online 中打开

If plot works in an axes with 'NextPlot' set to 'replace' (the default), a new plot replaces the old plot completely. Try this:

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);
handles.handle_plot2 = plot(X2,Y2);
guidata(hObject, handles);
