TaskWhat to Use? Graphs for statistical analysesStatistical procedures Stand-alone graphsSG Procedures Highly customized graphsGTL Enhancing graphs for presentationODS Graphics Editor Graphs without programmingODS Graphics Designer

Conclusion ODS Statistical Graphics is an exciting new functionality provided by SAS. It greatly enhances the ability of data visualization integrates the graphic display with the tabular output automates the production of statistical graphics maintains the ability to customize the displays by modifying the templates and styles create statistical graphs without knowledge of programming

Conclusion With SAS ODS Graphics, simpler and minimal coding is required to generate high quality statistical graphs. By spending less time in coding to improve the visual appearance of graphs for data visualization, we can focus more on the statistical analysis.
