Bar-Line graph

A user recently posted a question in the SAS communities forum about  how to best display two measures by one classifier using a Bar-Line graph, where the scale of the two measures is vastly different.  This got me thinking about various different ways to represent such data.  Here are some of my thoughts,

Cluster groups

The topic of cluster groups comes up often.  By cluster group I am referring to the feature in bar charts where the group values are displayed side by side. With SAS 9.3, SG Procedures support stack or cluster grouping for Bar Charts and overlay or cluster grouping for all other

ODS Graphics system was initially motivated by the need for high quality graphs for SAS Base, STAT, and other analytical procedures.  Use of SG Procedures, ODS Graphics Designer and GTL by users too has initially focused on analytical graphs.  But just like wheels on carryon bags that started for the specific needs of flight

High resolution graphs

Creating a graph that looks nice, with readable, high resolution fonts is important and should be easy to do.  With SG procedures and GTL, this is easy to do with a simple option, but not the default. Creating a high resolution (image) for a graph consumes higher system resources.  When working on a graph,

Graphs with class

When the data is classified by multiple class variables, you can certainly create graphs using BY variables.  This results in separate graphs, one for each level of the BY variable crossings.  Each graph is scaled by its own data subset, and comparisons across BY levels is harder. When comparisons need to be
