Matplotlib animate over an image

I'm trying to animate a bunch of constantly updating points over an image (imagine making a plotted dot move diagonally across some image). I've looked at the animate examples here: http://matplotlib.org/examples/animation/dynamic_image.html, but I'm not sure how to keep the same image while clearing out all previous dots, then redrawing them. Any ideas?

You do not need to clear the figure between every frame

#initial data 
ln, = ax.plot(x,y)
#...some loop code
    ln.set_xdata(new_x)
    ln.set_ydata(new_y)

Can you show some code of what you have tried, it will make it easier to give a more concrete answer.
