    t=[ %to print text
    text(2,3.5,'')
    text(2,3,'')
    text(2,2.5,'') 
    text(2,2,'')
    text(2,1.5,'')  
    ];
    
    for i = 200:10:2700  
    % Forward kinematics
    th1 = simOut.ScopeData.signals.values(i,1);
    th2 = simOut.ScopeData.signals.values(i,2);
    th3 = simOut.ScopeData.signals.values(i,3);
    
    x1 = L1*cos(th1);
    y1 = L1*sin(th1);
    x2 = L2*cos(th1 + th2) + x1;
    y2 = L2*sin(th1 + th2) + y1;
    x3 = L3*cos(th1 + th2 + th3) + x2;
    y3 = L3*sin(th1 + th2 + th3) + y2;
    
    set(t(1),'String',sprintf('X : %.2f',x3));
    set(t(2),'String',sprintf('Y : %.2f',y3));
    set(t(3),'String',sprintf('joint 1 angle : %.2f',th1*180/pi));
    set(t(4),'String',sprintf('joint 2 angle : %.2f',th2*180/pi));
    set(t(5),'String',sprintf('joint 3 angle : %.2f',th3*180/pi)); % I want to plot without removing the text.
    hold on
    plot(x1, y1, 'ok', 'Linewidth', 2)   % joint 1
    plot(x2, y2, 'ok', 'Linewidth', 2)   % joint 2
    plot(x3, y3, 'ok', 'Linewidth', 2)   % joint 3
    plot([ox, x1],[oy, y1], 'r', 'Linewidth', 2)  % link 1
    plot([x1, x2],[y1, y2], 'b', 'Linewidth', 2)  % link 2
    plot([x2, x3],[y2, y3], 'g', 'Linewidth', 2)  % link 3
    hold off
    max_L = L1+L2+1;
    axis([-max_L max_L -max_L max_L])
    grid on
