Good Day everyone Ma'am and sir. i'm really sorry for your time. i just practiced the code that have shared in this group but application in 6 storey building. im really worried because it dont appread the plot on on the axis.

function THAsel_Callback(hObject, eventdata, handles)
THAsel=get(handles.THAsel,'Value');
clc
switch THAsel
    case 1  %First floor
        modesel=1; 
    case 2  %Second floor
        modesel=2; 
    case 3  %Third floor
        modesel=3;
    case 4  %Forth floor
        modesel=4;
    case 5  %Fifth floor
        modesel=5;
    case 6  % Sixth floor
        modesel=6;
    case 7 %whole building displacements
        modesel=7;
    case 8 %whole building velocity
        modesel=8;
    case 9  %whole building acceleration
        modesel=9;
end
