ODS Statistical Graphics

November 10, 2004

Linda Atkinson

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
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
Procedures (cont.)
• SAS/STAT
• ANOVA ▪ LOGISTIC
• CORRESP ▪ MI
• GAM ▪ MIXED
• GENMOD ▪ PHREG
• GLM ▪ PRINCOMP
• KDE ▪ PRINQUAL
• LIFETEST ▪ REG
• LOESS ▪ ROBUSTREG
A Simple Example

ods html;

ods graphics on;

procreg data=sashelp.class;

model weight=height;

run;

quit;

ods graphics off;

ods html close;

Specifying a Destination

ods pdf file='d:\odsdemo\diagnostics.pdf';

ods graphics on;

procreg data=sashelp.class;

model weight=height;

run;

quit;

ods graphics off;

ods pdf close;

Changing style

ods pdf file='d:\odsdemo\diagnostics.pdf'

style=analysis;

ods graphics on;

procreg data=sashelp.class;

model weight=height;

run;

quit;

ods graphics off;

ods pdf close;

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

Default Style

Journal Style

Analysis Style

Statistical Style

Selecting graphs

ods html style=default;

ods graphics on;

ods trace on; /* Lists the output objects created by ODS. */

proc reg data=sashelp.class plots(unpack);

/* UNPACK option displays plots individually instead of

in a panel. */

model weight=height;

run;

quit;

ods graphics off;

ods html close;

ods trace off;

Trace output

-------------

Name: ResidualHistogram

Label: Residual Histogram

Template: Stat.REG.Graphics.ResidualHistogram

Path: Reg.MODEL1.ObswiseStats.Weight.DiagnosticPlots.ResidualHistogram

-------------

-------------

Name: ResidualByPredicted

Label: Residual By Predicted

Template: Stat.REG.Graphics.ResidualByPredicted

Path: Reg.MODEL1.ObswiseStats.Weight.DiagnosticPlots.ResidualByPredicted

Selecting graphs (cont.)

ods html style=default;

ods graphics on;

ods select residualhistogram;

procreg data=sashelp.class plots(unpack);

model weight=height;

run;

quit;

ods graphics off;

ods html close;

Graph specification example

ods html;

ods graphics on;

proclifetest data=BMT;

time T * Status(0);

survival plots=(survival, hwb);

strata Group;

run;

ods graphics off;

ods html close;

Changing image file type

ods html;

ods graphics on / imagefmt=jpeg;

proclifetest data=BMT;

time T * Status(0);

survival plots=(survival, hwb);

strata Group;

run;

ods graphics off;

ods html close;

Creating graphs with tool tips

ods html file='d:\odsdemo\boxplots.html' gpath='d:\odsdemo';

/* gpath option specifies where to store graphics image files */

ods graphics on / imagefmt=staticmap;

/* staticmap option generates image map of coordinates

for tool tips */

procmixed data=pr method=ml boxplot(npanel=15);

class Person Gender;

model y = Gender Age Gender*Age;

random intercept Age / type=un subject=Person;

run;

ods graphics off;

ods html close;

Customizing Graphs

ods html;

ods graphics on;

procrobustreg data=growth plot=resqqplot;

model GDP = LFG GAP EQP NEQ;

run;

ods graphics off;

ods html close;

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.

sasuser.templat(update);

Modifying Styles

proctemplate;

define style styles.DemoStyle;

parent=styles.Default;

replace StatGraphFitLine / linestyle=2;

end;

run;

ods html style=DemoStyle;

ods graphics on;

procrobustreg data=growth plot=resqqplot;

model GDP = LFG GAP EQP NEQ;

run;

ods graphics off;

ods html close;
