As seen
so far, you can obtain analytical graphs automatically from SAS analytical
procedures. Furthermore, you can edit or customize these graphs with
the ODS Graphics Editor, all without any need to learn the GTL syntax.
However,
frequently you might need to get a better understanding of the data
in a study or survey by creating preliminary graphical views of the
data. Such views might be necessary before a decision can be made
about the detailed analysis process.
Also,
your task might require data analysis using multiple procedures and
some custom data management. After such analysis process, the results
contained in the output data sets might need to be displayed as custom
graphs.
Many such
graphs can be created using the Statistical Graphics (SG) Procedures.
The SG procedures are a set of graphics procedures that leverage
the power of GTL behind the scenes to create commonly used graphs
using a simple and concise syntax. The following new SG procedures
are available with SAS 9.2:
-
The SGPLOT procedure
for creating single-cell graphs.
-
The SGPANEL procedure
for creating multi-cell classification panels.
-
The SGSCATTER
procedure for creating multi-cell comparative scatter plots.
The SG
procedures also provide additional data summarization features that
are not provided by GTL. For many users, these procedures are the
right set of tools to use for meeting their needs, without deploying
the full power of GTL.
For more
information on the set of SG procedures, see the
SAS/GRAPH Statistical Graphics Procedures Guide.
