  • Multiple Graphs on One Page

  • Multiple Graphs on One PageOften it is useful to put several or even many graphs on one pageGraphs are created first and stored in a SAS graphics catalogUsing proc greplay a template can be defined and graphic elements put into the various panels

  • Defining a template can be tediousHere is the template definition code for a sample 3 panel template:

    tdef mytemp 1 / llx=0 ulx=0 lrx=100 urx=100 lly=0 lry=0 uly=100 ury=100 2 / llx=0 ulx=0 lrx=100 urx=100 lly=65 lry=65 uly=95 ury=95 3 / llx=0 ulx=0 lrx=100 urx=100 lly=35 lry=35 uly=65 ury=65 ;

    Rather than define the two opposite corners of a rectangle (to define a panel), SAS wants the user to define all four corners of each rectangle (each panel).Each (x,y) value is repeated twice, opening the door to human error. (Yes, Ive seen templates with crooked panels.)

  • PanelDef/********************************************************************** Name: PanelDef ** Desc: Returns the text for a greplay panel definition. ** Type: Graphics Utility ** History: ** 7/1/04 WJS **********************************************************************/%macro paneldef( pnlnbr , leftx , rightx , lowery , uppery , color ); %local return; %let return = &pnlnbr /; %let return = &return llx=&leftx ulx=&leftx lrx=&rightx urx=&rightx; %let return = &return lly=&lowery lry=&lowery uly=&uppery ury=&uppery; %if ( %length( &color ) > 0 ) %then %let return = &return color=&color;&return%mend;

  • Three Macros to Simplify Annotations

  • Three Macros to Simplify AnnotationsThe SAS annotate facility give great flexibility in writing or drawing things on graphs even producing specialized graphsTypically, simple text is dropped onto a graphLearning annotate is not difficult but takes time

  • Three simple macros can helpMacro avars creates the basic variable needed in a dataset to annotate a graphMacro xyhsys specifies a coordinate systemMacro alabel defines a text label, placed anywhere you need it

  • First an exampleThe following code defines a graph that has the titles for a Multi-graph page:

    data annotitles; %avars %xyhsys( 1,1,1 ) %alabel( 50,100, "&title1",,,, 3.5, centb,E ) %alabel( 50,95, "&title2",,,, 2.5, centb,E ) run; proc ganno annotate=annotitles gout=&mygout name='titles'; run;

  • avars/************************************************************ Name: avars ** Desc: Annotate macro to declare and size standard ** annotate dataset variables ** Type: Graphics Utility - Annotate Macro ** Walt Smith May 10, 2001 ************************************************************/%macro avars; length color function style $8; length text $200; length x y 8;%mend;

  • xyhsys/***************************************************************** Name: xyhsys ** Desc: Annotate macro to set the value of three annotate ** variables: xsys, ysys, and hsys. ** Type: Graphics Utility - Annotate Macro **---------------------------------------------------------------** ============================================= ** | Table of Coordinate System Codes | ** | (See SAS/Graph Software pg 476) | ** +-----------+---------+----------+----------+ ** | Area | Units | Absolute | Relative | ** +-----------+---------+----------+----------+ ** | Data | % | 1 | 7 | ** | Area | Values | 2 | 8 | ** +-----------+---------+----------+----------+ ** | Graphics | % | 3 | 9 | ** | Output | Cells | 4 | A | ** | Area | | | | ** +-----------+---------+----------+----------+ ** | Procedure | % | 5 | B | ** | Output | Cells | 6 | C | ** | Area | | | | ** ============================================= *****************************************************************/%macro xyhsys( xsys , ysys , hsys ); xsys = "&xsys"; ysys = "&ysys"; hsys = "&hsys";%mend;

  • alabel/************************************************************ Name: alabel ** Desc: Annotate macro to place text on a graph ** Type: Graphics Utility - Annotate Macro ** ** Walt Smith November 30, 1999 ** 5/8/02 WJS Modify logic for pos parm ************************************************************/%macro alabel (x,y,txt,coltxt,ang,rot,size,font,pos); %if ( %length( &x ) >0 ) %then x = &x %str(;); %if ( %length( &y ) >0 ) %then y = &y %str(;); %if ( %length( &ang ) >0 ) %then angle = &ang %str(;); %if ( %length( &rot ) >0 ) %then rotate = &rot %str(;); %if ( %length( &size ) >0 ) %then size = &size%str(;); %if ( %length( &txt ) >0 ) %then text = &txt %str(;); %if ( %length( &font ) >0 ) %then style = "&font"%str(;); %if ( %length( &pos ) =1 ) %then position = "&pos"%str(;); %else %if ( %length( &pos ) > 1 ) %then position = &pos %str(;); %if %length(&coltxt)>0 %then color = "&coltxt"%str(;); function='label'; output;%mend;

  • PROC SQL vs. PROC MEANS

    by John Ang Senior Merchandising Analyst AutoZone

  • Summary Functions in PROC SQLThe following summary functions are available when using PROC SQL:AVGCOUNTMINMAXSTDSUMVAR

    The GROUP BY statement is used in conjunction with these summary functions.

  • PROC SQL Query proc sql; create table boo as select hoo, sum(foo) as goo from doo group by hoo;quit;

  • Output Statistics in PROC MEANSThe following output statistics are available when using PROC SQL:MEANNMINMAXSTDSUMVAR

    The OUTPUT statement is used in conjunction with these output statistics.

  • PROC MEANS Query proc means data=doo sum mean noprint; class hoo; var foo; output out=boo sum=goo;run;

  • Comparison of SAS Log135 proc sql;136 create table boo as137 select hoo, sum(foo) as goo138 from doo139 group by hoo;NOTE: Table WORK.BOO created, with 18607 rows and 2 columns.

    140 quit;NOTE: PROCEDURE SQL used: real time 1:15.31 cpu time 46.82 seconds

    141 proc means data=doo sum mean noprint;142 class hoo;143 var foo;144 output out=boo2 sum=goo;145 run;

    NOTE: There were 20532029 observations read from the data set DAD5DATA.SSPOLK.NOTE: The data set WORK.BOO2 has 18608 observations and 2 variables.NOTE: PROCEDURE MEANS used: real time 39.10 seconds cpu time 34.89 seconds

  • Another Exampleproc means data=limahl.omd sum noprint; class time; var edge; output out=sting1 sum=toto;run;

    proc sql; create table sting2 as select time, sum(edge) as toto from limahl.omd group by time;quit;

  • Another SAS Log3 proc means data=limahl.omd sum noprint;4 class time;5 var edge;6 output out=sting1 sum=toto;7 run;

    NOTE: There were 444186953 observations read from the data set SREGDATA.VITEMADJ_DOWNLOAD.NOTE: The data set WORK.STING1 has 158234 observations and 4 variables.NOTE: PROCEDURE MEANS used: real time 23:16.58 cpu time 12:52.62

    89 proc sql;10 create table sting2 as11 select time, sum(edge) as toto12 from limahl.omd13 group by time;NOTE: Table WORK.STING2 created, with 158233 rows and 2 columns.

    14 quit;NOTE: PROCEDURE SQL used: real time 50:50.62 cpu time 23:33.05

  • PROC SQL or PROC MEANS? PROC SQL code can be more readable and easily understood by other SAS users.

    Generally, PROC MEANS will produce the same summarized result in less CPU time than PROC SQL will.

    More descriptive statistics (e.g. quantiles) are available with PROC MEANS th
