Overview

• ODS for Statistical Graphics
• enables you to create statistical graphics as
  automatically as tables are currently created
• provides commonly used displays, including
  scatter plots, histograms, box-and-whisker plots,
  and contour plots, in ODS output
• is experimental in SAS 9.1

3
Procedures

• Procedures supporting ODS Graphics in SAS 9.1
• Base SAS ? TIMESERIES
• CORR ? UCM
• SAS/ETS ? VARMAX
• ARIMA ? X12
• AUTOREG SAS High-Performance Forecasting
• ENTROPY ? HPF
• EXPAND
• MODEL
• SYSLIN

4
Procedures (cont.)

• SAS/STAT
• ANOVA ? LOGISTIC
• CORRESP ? MI
• GAM ? MIXED
• GENMOD ? PHREG
• GLM ? PRINCOMP
• KDE ? PRINQUAL
• LIFETEST ? REG
• LOESS ? ROBUSTREG

Recommended styles

• Four SAS-supplied styles are recommended for use
  with ODS Graphics
• Analysis
• Default
• Journal
• Statistical

Reverting to Default Templates

• Customized templates are stored in
  Sasuser.Templat or in user-defined template
  stores. The default templates provided by SAS are
  saved in the read-only template store
  Sashelp.Tmplmst. Consequently, if you have
  modified any of the default templates and you
  want to create ODS Graphics with the original
  default templates, one way to do so is by
  changing your ODS path as follows.
• ods path sashelp.tmplmst(read)
• sasuser.templat(update)
