double plot not properly working with checkboxes in appdesigner Matlab (R2020a)

i have designed a interface for single or double plot which i control through Check Boxes. inshort the problem is when i run the code first time its double plot perfectly but when uncheck one checkbox and recheck then double plot not shown.

it is working 90% fine

when i click first checkbox it plot... i uncheck it disappears.. same for second choice.

when i click both checkboxes it double plot and when it uncheck "S" only "L" plot shows.

but problem start when at this stage i again click "S" checkbox while "L" checkbox is already selected then it only plotting "S", it should again double plot. this may be little bit confusing to explain thats why i attached GIF for demonstration... also code file attached... kindly suggest some solution.

function plotwidth(app)

M % Property Used

a = 0:0.1:2*pi;

b = sin(a);

c = cos(a);

if app.LCheckBox.Value && ~app.SCheckBox.Value

app.UIAxes.cla;

app.M = plot(app.UIAxes,a,b);

elseif app.SCheckBox.Value && ~app.LCheckBox.Value

app.UIAxes.cla;

app.M = plot(app.UIAxes,a,c);

elseif app.LCheckBox.Value && app.SCheckBox.Value

app.N = plot(app.UIAxes,a,b);

hold(app.UIAxes);

app.M = plot(app.UIAxes,a,c);

else

app.M.Visible = 'off';

end

end

maybe this will work for you:

fig=figure();
button1=uicontrol(fig,'Style','checkbox','Position',[100 1 50 22],'String','S');
button2=uicontrol(fig,'Style','checkbox','Position',[10 1 50 22],'String','L');

hold on
plot1 = plot(1:10);
plot2 = plot(10:-1:1);
while 0<1
    if button1.Value==0
        set(plot1(1),'Visible','off');
    elseif button1.Value==1
        set(plot1(1),'Visible','on');
    end
    if button2.Value==0
        set(plot2(1),'Visible','off');
    elseif button2.Value==1
        set(plot2(1),'Visible','on');
    end
    pause(0.1)
end
