I have set of centroid values (horizontal and vertical) for an image. I want to plot these points on a 2D graph. I am not looking for a line or curve plot. Can someone help me in this?

Does work? I am assuming your data is a collection of (x,y) pairs, and you want to plot these as points in a 2D plot. has a complete listing of discrete data plots available.

You can use scatter() or plot(). You don't have to have lines in plot() - you can just use the markers if you want. But you might have to set ydir to 'reverse' if you want the orientation to be the same as your image (basically upside down since images have row 1 at the top and gets larger as it goes down the screen).
