GDRAW functions create
graphics elements. Each GDRAW operator is associated with a set of
GSET operators that control its attributes. The color, height, and
font attributes, for the GDRAW('TEXT', . . . ) function are controlled
by GSET('TEXCOLOR', . . . ), GSET('TEXHEIGHT', . . . ), and GSET('TEXFONT',
. . . ), respectively. For a complete list of the attributes associated
with each GDRAW function, see
DATA Step Graphics Interface Routines. The complete graph is displayed after the GRAPH('UPDATE',
. . . ) function is submitted.
When using GDRAW functions,
remember the following:
-
All arguments must be specified.
-
All arguments are specified as
variables or constants.
-
If you express an argument as a
variable, the variable must be initialized.
-
All character arguments expressed
as character strings must be enclosed in quotes.
-
All character variable names used
as arguments must be declared in a LENGTH statement.
-
All character constants must be
enclosed in single or double quotes.
