Delete that first line, the clc and so on. Put the rest within a callback of a uicontrol. See GUIDE to create a simple GUI

howlong = str2double(get(handles.edit1, 'String'));
while toc < howlong

thanks for your helps :) but i want to ask one more thing.
how can i change plot color with listbox ?
i tried this in callback but did not work.
ciz_renk=get(handles.listbox1,'value');
switch ciz_renk
case 1
set(hline,'color','b');
case 2
set(hline,'color','r');
case 3
set(hline,'color','g');
end

That should work as long as hline is the line handle and you make the change after you draw the line.
