hi,
as i mentioned in my previous message that i am using the following code to plot two different types of data on two axes. One of them is 'xls' and the other one is 'ascii'.
now the next task is the implementation of a slider at the horizontal position for the both axes so when i zoom in into the axes and the graph expand then with help of this slider i should move from left to right or right to left along the graph.
i am not very familier to matlab and this is the part of a project which i have to finish in 1 week so i,ll be very thankful if any body can help me in detail for this part of my project.
here are the codes from my m.file

function varargout = ekg_vis(varargin)
gui_Singleton = 1;
gui_State = struct('gui_Name', mfilename, ...
'gui_Singleton', gui_Singleton, ...
'gui_OpeningFcn', @ekg_vis_OpeningFcn, ...
'gui_OutputFcn', @ekg_vis_OutputFcn, ...
'gui_LayoutFcn', [] , ...
'gui_Callback', []);
if nargin && ischar(varargin{1})
gui_State.gui_Callback = str2func(varargin{1});
end

if nargout
[varargout{1:nargout}] = gui_mainfcn(gui_State, varargin{:});
else
gui_mainfcn(gui_State, varargin{:});
end
% End initialization code - DO NOT EDIT

file = '';


% --- Executes just before ekg_vis is made visible.
function ekg_vis_OpeningFcn(hObject, eventdata, handles, varargin)

% hObject handle to figure

% Choose default command line output for ekg_vis
handles.output = hObject;

% Update handles structure
guidata(hObject, handles);
set(hObject, 'toolbar','figure');


% This sets up the initial plot - only do when we are invisible
% so window can get raised using ekg_vis.
%if strcmp(get(hObject,'Visible'),'off')
% plot(rand(5));
%end
