ODS graphics are generated
by template definitions that determine a graph’s layout and
appearance and specify the variable roles to be represented in the
graph display. A graph can be rendered from a compiled template by
associating the template with a data source at run time.
The following SAS program
shows the basic structure needed to meet the minimum requirements
for generating a plot using GTL:
proc template;
define statgraph minimumreq;
begingraph;
layout overlay;
scatterplot x=weight y=height;
endlayout;
endgraph;
end;
run;
proc sgrender data=sashelp.class template=minimumreq;
run;
-
The DEFINE STATGRAPH statement
on PROC TEMPLATE is required to open a definition block for defining
and naming a graphics template. The END statement closes the template
definition.
-
A BEGINGRAPH statement block is
required to define the outermost container for the graph. The ENDGRAPH
statement closes the block.
-
At least one layout statement block
is required for specifying the elements that compose the graph. To
generate a plot, the layout block must contain at least one plot statement.
The ENDLAYOUT statement closes the layout block.
-
The PROC TEMPLATE statement must
be run to compile the template and save it in the template store (SASUSER.TEMPLAT
by default).
-
The PROC SGRENDER statement is
required to produce a graph from a compiled template. The DATA= option
specifies a run-time data source to use, and the TEMPLATE= option
specifies the template to use. The input data source must satisfy
any restrictions that are imposed by the template. For example, it
must contain any variables that have been specified on the template’s
GTL statements.
