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

classdef app1 < matlab.apps.AppBase

% Properties that correspond to app components

else

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
