How to add GUI for existing code

Hi everyone,

I have a written code of vibration shape mode. Since there are too many curves in my plot, I'm thinking about using popup menu to organize them. However, I don't know how to make it work after I created my GUI. I've tried to put my entire code into the callback of popupmenu function but it didn't work. Here's how I'm plotting it right now. I want to make the corresponding plot everytime I pick a k value from the popup menu. Can someone help me with it?

%Assign each interior displacement to its location
figure(1)
for k=1:s_e%looping over frequencies
    for i=1:n%looping over elements
    %Plot 14.4c elemental displacement
    plot(l(i,:),vd{k}(i,:),'-x')
    
    hold on
    grid on
    plot(l_b,vd_b,'-ko')%Original beam plot
    
    end
title('Vibration mode shape with 4 elements')

%Show max displacement point for each graph
MaxVd{k}=max(max(vd{k}));
indexofMax=find(vd{k}==MaxVd{k},1,'first');
maxY=vd{k}(indexofMax);
maxX=l(indexofMax);
plot(maxX,maxY,'-k^');
text(maxX,maxY,['(' num2str(maxX) ',' num2str(maxY) ')'],'HorizontalAlignment','right','FontSize',7);
end
hold off

figure;
axes('NextPlot', 'add');  % same as "hold on"
grid on                   % Once only!
plot(l_b,vd_b,'-ko')      % Once only! Original beam plot

HandleList = cell(1, s_e);
for k=1:s_e   % looping over frequencies
    H = gobjects(1, n + 2);
    for i=1:n % looping over elements
    %Plot 14.4c elemental displacement
      H(i) = plot(l(i,:),vd{k}(i,:),'-x')
    end
    title('Vibration mode shape with 4 elements')
    %Show max displacement point for each graph
    MaxVd{k}=max(max(vd{k}));
    indexofMax=find(vd{k}==MaxVd{k},1,'first');
    maxY=vd{k}(indexofMax);
    maxX=l(indexofMax);
    H(n+1) = plot(maxX,maxY,'-k^');
    H(n+2) = text(maxX,maxY,['(' num2str(maxX) ',' num2str(maxY) ')'], ...
        'HorizontalAlignment','right','FontSize',7);
    HandleList{k} = H;
end
allHandle = cat(2, HandleList{:});
set(allHandle, 'Visible', 'off')

Then provide HandleList as input of the callback of the popup menu:

uicontrol('Style', 'popup', 'String', sprintfc('%d', 1:s_e), ...
    'Callback', {@myPopupCB, HandleList}, ...
    'Position', [5, 5, 80, 22]);

And the callback:

function myPopupCB(PopupH, EventData, HandleList)
value = get(PopupH, 'Value');
for k = 1:numel(HandleList)
    if ismember(k, value)
        set(HandleList{k}, 'Visible', 'on');
    else
        set(HandleList{k}, 'Visible', 'off');
    end
end
drawnow;
end

Thank you.I will try it on later tomorrow morning.
