button in a figure

How to add a button in a figure that changes the line style of a subplot,without using GUIDE?

Maybe I misunderstand, but isn't a button that a user pushes, by definition, a graphical user interface?

try this:

S.f = figure; S.h=plot(rand(10,1)); % creates a figure and plot something on it
% create a pushbtton ( adapt it to your needs)
S.pb = uicontrol('style','push',...
                 'units','pix',...
                 'position',[10 10 180 40],...
                 'fontsize',14,...
                 'string','Change line',...
                 'callback',{@pb_call,S});

%callback function for the pushbutton  (save it in its own *.m file if needed)           
function pb_call(varargin)
S = varargin{3};  % Get the structure.
set(S.h,'LineStyle','+')
