How to plot according to DropDown menu value?

I want to plot in a UIAxes the selected option in the dropdown menu. Please help!

%There are 2 options in the DropDown menu (Square and Cube)
%This is what I've got so far..
        function DropDownValueChanged(app, event)
             value = app.DropDown.Value;
             if value == Square
                x = 1:5
                y = (x.^2)
                plot(app.UIAxes5, x,y)  
             end
             if value == Cube
                x = 1:5
                y = (x.^3)
                plot(app.UIAxes5, x,y)  
             end
             
        end

if value == Square

Well, this is certainly not going to work (unless you've created a Square variable)

I suspect that

if value == "Square"

may work better, but that really depends on what you've put in the Items and ItemsData property of your dropdown (which you haven't told us).
