In reply to Yannick.

There are two ways to generate ODS statistical graphics in SAS. For many common graphs with one panel, you can use PROC SGPLOT, which supports bar charts, histograms, scatter plots, etc, with simple overlays. For more complex graphs, you can use PROC TEMPLATE and the Graph Template Language (GTL) to define different cells that contain graphical elements. When you do that, PROC SGRENDER is used to read the template and create the graphh.
