Advanced ODS Graphics: A deeper dive into documents, dynamics, and data objects

You can modify all of the components of the graphs that analytical procedures produce: the data object, graph template, and the dynamic variables. This blog takes a closer look at dynamic variables (which you can see by using PROC DOCUMENT) and data objects and explores graphs that are constructed from more than one data object.

Advanced ODS Graphics: Examining and processing templates

This blog shows a variety of techniques including how to use PROC TEMPLATE and the SOURCE statement, PROC SGPLOT with multiple Y-axis tables, create comparable axes in two side-by-side graphs, create a broken axis, write and use a table template that wraps text, and find and display examples of certain statements in graph templates and fonts in style templates.

The BEST D formats that you have ever seen!

The Dw.p format displays numeric values, in a field w positions wide, possibly with a great range of values, lining up decimals for values of similar magnitude. The BESTDw.pformat combines the BESTw. format for integers and the Dw.p format for nonintegers. Specifying BESTDw.p (where p = w - 1) is better than specifying BESTw. for columns, since decimals do not shift when the last digit is 0.
