Plotting points only at integer coordinates

[Dustinsfl]

I am trying to plot a graph with the domain and range as integers. So instead of a continuous function, I will have points only plotted on the integers.

Does anyone know how to do this?

Graphs
The plot command may be used to plot simple graphs,
plot( x^3, x=-3..3); ......

Those will yield all continuous graphs. The domain and range of the function I am using are integers not real numbers so I need a calling method that will only plot at the integers.
