Comparing with other software/tools for generating the graphs,
SAS/Graph may be inferior. Programming to generate graphs using SAS/Graph
languages can be time consuming and the quality of the graphs is usually not so
great and not in publication quality. It is also not easy to output the graphs
in the commonly used format. With SAS/Graph, we usually create the graph files
in .cgm and then use a MS Word macro to load the .cgm files into MS Word file.
Now SAS has offered two new ways to generate the graphs: SASODS Graphics and SAS Stat Graphics. I had previously discussed SAS ODS Graphicswith template using Proc Lifetest to generate the Kaplan-Meier curve.
The procedure SGPLOT in SAS ODS Graphics can be used to
generate high quality graph. With SGPLOT available, SAS/Graph procedure GPLOT
become obsolete. The programs below illustrate the use of SGPLOT to generate
the time-concentration curve for PK concentration data.
The graph generated from the programs is directly outputted
in a .pdf file.

very use full and informative post
Is it compulsory to exclude the subjects who found predose concentration more than five % of Cmax in endogenous molecule?
