ODS Graphics works differently from SAS/GRAPH procedures. ODS Graphics output goes to open ODS destinations like HTML and PDF. ODS Graphics produces output in industry standard formats like PNG, PDF, SVG and many more. ODS Graphics produces high resolution graphs. Setting high DPI scales all aspects of the graph, including marker size and line .
SAS Output Delivery System (ODS) Graphics started appearing in SAS 9.2. Collectively these new tools were referred to as "ODS Graphics," "SG Graphics" and "Statistical Graphics". When first starting to use these tools, the traditional SAS/GRAPH software user might come upon some very significant
What's New in SAS ODS Graphics This session explores the new graphical capabilities available directly from many existing SAS procedures and the new SG procedures. Also, learn more about what's new in ODS Graphics, including the ODS Graphics Designer, the ODS Graphics Editor, and the Graph Template Language. Updated to include 9.3 changes.
Paper SAS5443-2016 The Dynamic Duo: ODS Layout and the ODS Destination for PowerPoint Jane Eslinger, SAS Institute Inc. ABSTRACT Like a good pitcher and catcher in baseball, ODS layout and the ODS destination for PowerPoint are a winning combination in SAS 9.4. With this dynamic duo, you can go straight from performing data
Evolution of ODS Graphics Early Development of SAS Graphics In the beginning SAS had a less than stellar reputation regarding graphics output. PROC PLOT produced crude raster graphics using a line printer. Then there was SAS/GRAPH and visuals became better. Vector graphics used to produce quality output. Lots of options but too many to learn well (difficult to use “on the fly”).
ODS Graphics Designer Drag & drop, point & click version of graphics -Wide array of plot types -Produces sophisticated graphs ODS Graphics Designer writes the code for you

United States Steel Corporation Preproduction in SAS 9.2 Release 2 (TS2M0) Part of Base SAS in 9.3 (No need for SAS/GRAPH) Drag & Drop and Point & Click version of SG Graphics Let ODS Graphics Designer write the code for you
ODS Graphics is one of the systems used to create analytical graphs in SAS First released with SAS 9.2 as part of SAS/GRAPH From SAS 9.3 onwards, ODS Graphics is part of Base SAS With this system, many SAS analytical procedures create graphics output automatically This system also provides other ways to create custom graphs
