Hello,

I am trying to design a simple app on app designer with 3 components, a UI axes, a drop down menu, and radio buttons. The drop down menu has two options to select from as a starting place, the user would then have to choose one of two options from the drop down menu in order to display the corresponding plot (total 4 plots for each case):

Plots:

1) Periodic & pretty plot (x1,y1)

2) Periodic & not pretty plot (x4,y4)

3) Non periodic & not pretty plot (x2,y2)

4) Non periodic & pretty plot ( x3,y3)

My attempt at this is to first read the table from the excel file I have, and then use switch/case statements along with if else conditions as follows:

classdef Simple_App_Test < matlab.apps.AppBase
    % Properties that correspond to app components
    properties (Access = public)
        UIFigure             matlab.ui.Figure
        UIAxes               matlab.ui.control.UIAxes
        BeautyDropDownLabel  matlab.ui.control.Label
        BeautyDropDown       matlab.ui.control.DropDown
        DataTypeButtonGroup  matlab.ui.container.ButtonGroup
        PeriodicButton       matlab.ui.control.RadioButton
        NonperiodicButton    matlab.ui.control.RadioButton
    end
    % Callbacks that handle component events
    methods (Access = private)
        % Code that executes after component creation
        function startupFcn(app)
            dataset = readtable('App_test.xlsx');
            x1 = dataset(:,1);
            x2 = dataset(:,3);
            x3 = dataset(:,5);
            x4 = dataset(:,7);
            y1 = dataset(:,2);
            y2 = dataset(:,4);
            y3 = dataset(:,6);
            y4 = dataset(:,8);
        end
        % Selection changed function: DataTypeButtonGroup
        function DataTypeButtonGroupSelectionChanged(app, event)
            selectedButton = app.DataTypeButtonGroup.SelectedObject;
            value = app.DataTypeButtonGroup.Value;
            switch value
                case "Periodic"
                    if app.BeautyDropDown.Value == 'Pretty'
                        plot(app.UIAxes,x1,y1);
                    else
                        plot(app.UIAxes,x4,y4);
                    end
                case "Non periodic"     
                    if app.BeautyDropDown.Value == 'Not Pretty'
                        plot(app.UIAxes,x2,y2);
                    else
                        plot(app.UIAxes,x3,y3);
