SAS/GRAPH PROCEDURESOverview

“SG” Procedures

family of new procedures

general-purpose visual data analysis

complement specialized analytic proc graphics

clear and concise syntax.

compact code ( not much typing )

Capabilities always expanding

(new in SAS 9.2 Phase 1)

complete page of enhancements

(new in SAS 9.2 Phase 2)

vector plot type for the SGPLOT and SGPANEL

new panel layout types for the SGPANEL

more options are available for PANELBY statement

SGScatter has enhanced support for transparency

…

SAS/GRAPH PROCEDURESProc SgPlot – Basic Graph

proc sgplot data=sashelp.class;

Working with TemplatesWhy Create or Modify Graphic Templates

Analytic Proc Graphics

enhance default graphic cosmetics

axis labels, fonts, fills, etc (Graphics Editor)

add/change actual graphics produced

may be missing useful diagnostic or overlay, etc

extract and generalize a useful graphic

SG Procs

enhance graphic produced by procs

source of GTL to use in manually editted templates

ODS Graphics Designer

enhance graphic produced by GUI

generalize graphic (use with other data and in programs)

Create from Scratch

Create complex graphics not otherwise possible

Very efficient if you are GTL expert

Working with TemplatesComplex Graphics Possible with GTL

Execute Proc SGRender ( data _null_ still supported)

supply dataset

basic Syntax%let mVar1=ABC;* define character macro variable(s);

Working with TemplatesGTL Overview

Graphics Template Language

Comprehensive

allows for many combinations of basic plots

allows for many arrangements(layouts)

large number of options for everything

Smart

has good defaults for unspecified options

label collision algorithms

policies for axis text /scale

aware of scaling e.g. label vs. short label

auto placement of legends and text

built-in computational capabilities

built-in conditional rendering logic

Types of Statements

Conditional : what graph features are rendered

Layout : hierarchical arrangement of graph features

Plot : request specific plots (Overlay)

Axis : specify axis

Text : titles, footnotes , notes

Legend : request and arrange legends
