% eventdata  reserved - to be defined in a future version of MATLAB
% handles    structure with handles and user data (see GUIDATA)
data=get(handles.uitable1,'data');

y=data(:,2);
plot(x,y) 
% --- Executes on button press in save.

You need to

set(handles.uitable1, 'data', mat2cell(handles.data))

Also, when you plot,you should use

data = cell2mat(get(handles.uitable1, 'data'));

That is, uitable() take cell array for their data.

Thanks for reply.i have copied these two lines in my load callback function and when i am calling load callback function it is showing error message like index exceeds max dimension.and in handles.data it is showing 0*0 matrix.how to proceed. thanks rafi
