How to plot data inside a for loop?

I would like to know how to plot a graph in a GUI like a scope or moving graph as the data point is simulated inside a for loop. and also how to move x-axis which is time in my problem along with the graph. For example how to plot a moving sin wave with respect to time.

A simple way:

n = 0:199;

for nn = 1:length(n)
  plot(cos(pi/4*(n(1:nn))));
  axis([1 100 -1 1]);
  pause(0.2);
  hold on;
end

First: i dont want to use plot every time. I'm thinking of more like updating.

Second: The graphs is not moving to left after the data points crossed 100

Wayne's example contains all commands, which are necessary to solve your demands. Did you try to modify it?
