% SIGNAL MATLAB code for Signal.fig

%
% H = SIGNAL returns the handle to a new SIGNAL or the handle to
% the existing singleton*.
%
% SIGNAL('CALLBACK',hObject,eventData,handles,...) calls the local
% function named CALLBACK in SIGNAL.M with the given input arguments.
%
% SIGNAL('Property','Value',...) creates a new SIGNAL or raises the
% existing singleton*. Starting from the left, property value pairs are
% applied to the GUI before Signal_OpeningFcn gets called. An
% unrecognized property name or invalid value makes property application
% stop. All inputs are passed to Signal_OpeningFcn via varargin.

How can i fit that code to display an ECG signal and Move with a slider along x-axis ?
