Hello everyone,
On the figure , i would like all the experiment to be done between x=[-10 ;10] and y= [-10 ; 10] . The figure always centers the lines on the screen when they are plotted. I was expecting to have some lines on the left , right depending on the coordinates. The lines are been called from an excel file.
function varargout = Hapticfinal(varargin)
% HAPTICFINAL MATLAB code for Hapticfinal.fig
% HAPTICFINAL, by itself, creates a new HAPTICFINAL or raises the existing
% singleton*.
%
% H = HAPTICFINAL returns the handle to a new HAPTICFINAL or the handle to
% the existing singleton*.
%
% HAPTICFINAL('CALLBACK',hObject,eventData,handles,...) calls the local
% function named CALLBACK in HAPTICFINAL.M with the given input arguments.
%
% HAPTICFINAL('Property','Value',...) creates a new HAPTICFINAL or raises the
% existing singleton*. Starting from the left, property value pairs are
% handleslied to the GUI before Hapticfinal_OpeningFcn gets called. An
% unrecognized property name or invalid value makes property handleslication
% stop. All inputs are passed to Hapticfinal_OpeningFcn via varargin.
%
% *See GUI Options on GUIDE's Tools menu. Choose "GUI allows only one
% instance to run (singleton)".

The limits are no property of the figure, but of the axes. Simply set fixed limits, e.g. here:
set(handles.axes1,'XGrid','on','YGrid','on', ...
... % Added:
'XLim', [-8, 12], 'YLim', [-5, 27]);
