Hi,
% code
h = animatedline('Marker','o');
A = [1 1 2 5 9 8 7 6 3];
B = [20 30 50 10 85 95 5 8 9];
for k = 1:length(A)
addpoints(h,A(k),B(k))
xlim([min(A) max(A)]);
ylim([min(B) max(B)]);
drawnow limitrate
pause(0.7)
end

The example for drawnow should be easy to adapt for your purposes. You can then insert the function pause(.5) into the for loop to wait the .5 seconds before the next point.
http://www.mathworks.com/help/matlab/ref/drawnow.html
A=[1 1 2 5 9 8 7 6 3];
B=A(1);
h = plot(B,'YDataSource','B');
for k = 1:length(A)
B=A(1:k);
refreshdata(h,'caller')
drawnow
pause(.5)
end
