One thing you can do is add new data to an already existing plot.
figure;
plot(1:10,1:10);
ah = gca;
for loopIX = 11:100
%New Data becomes available
newXValue = loopIX;
newYValue = rand;
%Add the new data to the plot
ah.Children.XData(end+1) = newXValue;
ah.Children.YData(end+1) = newYValue;
end
Note that you may get warnings about the data arrays being sized wrong between the Xdata update and the Ydata update.

alcides silva:
At each time that you have a new point available, call addpoints() on the animatedLine() object, and then call drawnow().
Depending on your needs, you might want to set the 'MaximumNumPoints' option when you create the animatedLine
