This page presents examples of graphics programs written by ATS stat consultants. You can obtain these programs by typing,

searchcommand_name, into the Stata command line and following the instructions (see How can I use the search command to search for programs and get additional help? for more information about usingsearch).This page contains only the commands and the plots themselves, there is no further explanation. We envision that users will look through the plots and when they find one that appears to do what they want, they will download the program and carefully read the help files.

Most of these examples use the

hsb2dataset which can be downloaded from within Stata using the following command:

use https://stats.idre.ucla.edu/stat/stata/notes3/hsb2, clear

Note: Most of the graphs were produced using the scheme

lean1. Whenever a different scheme is used, it is given in the command.
