i had created a app through app designer ,which import and read data from excel and shos it in uitable now i have put two dropdown meny one for x and one for y and the user selects the column name to plot accordingly ,now i have to modify the code so that i can select multiplecolumn names from dropdown menu so that multiple graph would come according to user selection .

below is my code which i have written ,plzz help me modify it

classdef app1 < matlab.apps.AppBase

% Properties that correspond to app components

properties (Access = public)

UIFigure matlab.ui.Figure

readexcelButton matlab.ui.control.Button

yDropDownLabel matlab.ui.control.Label

yDropDown matlab.ui.control.DropDown

UIAxes matlab.ui.control.UIAxes

end

[file, path] = uigetfile('*.xlsx');

if isequal(file,0)

msgbox('Please input an Excel file')

else

t = readtable(fullfile(path, file));

app.UITable.Data = t;

% Set column names as a pull down menu

app.xDropDown.Items = t.Properties.VariableNames;

app.yDropDown.Items = t.Properties.VariableNames;

plot(app.UIAxes, app.UITable.Data.(app.xDropDown.Value), app.UITable.Data.(app.yDropDown.Value));

end

end

% Value changed function: xDropDown

function xDropDownValueChanged(app, event)

value = app.xDropDown.Value;

plot(app.UIAxes, app.UITable.Data.(app.xDropDown.Value), app.UITable.Data.(app.yDropDown.Value));

end

% Value changed function: yDropDown

function yDropDownValueChanged(app, event)
