I would certainly recommend installing my Graphs app sooner, rather than later, as the next time I add a new question the price will have to be increased. It can be installed now from Google Play, Amazon Appstore and Chrome Web Store, depending on your preferred platform.
“Graphs: How Do You Do This in SAS?” looks at generating graphs using classic SAS/GRAPH and the new ODS Graphics. I’ve added a question that looks at how an information box (graph inset) can be added to line graphs in ODS Graphics, as compared to using Annotate in SAS/GRAPH.
The latest versions of all the apps can be found here.
