This module shows examples of the different kinds of graphs that can be created with the graph twoway command. This is illustrated by showing the command and the resulting graph. For more information, see the Stata Graphics Manual available over the web and from within Stata by typing help graph, and in particular the section on Two Way Scatterplots.
