G

geo-variable

the $GEOREF formatted variable in a feature table that stores the spatial information as a geometry object. When a feature table is used, this variable is specified in the ID statement of the GMAP procedure. See also $GEOREF variable, identification variable, and feature table.

$GEOREF format

a geometric coordinate data arrangement that stores all the spatial information as a geometry object contained in a single variable. This format, which is used by feature tables, references to the geometry objects that encapsulate the points, lines, and polygons necessary to render a map. See also geo-variable and feature table.

global statement

a SAS statement that you can specify anywhere in a SAS program.

graph

a visual representation of data showing the variation of a variable in comparison to one or more other variables .

graphics element

a discrete visual part of a picture. For example, a bar in a chart and a plot s axis label are both graphics elements.

graphics device

See graphics output device.

graphics option

a value specified in a GOPTIONS statement that controls some attribute of the graphics output. The values specified remain in effect only for the duration of the SAS session. Some graphics options override device parameters.

graphics output

output from a graphics program that can be stored as a catalog entry of type GRSEG, or as a graphics stream file. Graphics output can be displayed or printed on a graphics output device. See also graphics output device and graphics stream file (GSF).

graphics output area

the area of a graphics output device where the graphics output is displayed or drawn. Typically, the graphics output area occupies the full drawing area of the device, but the dimensions of the graphics output area can be changed with graphics options or device parameters. See also procedure output area and graphics output device.

graphics output device

any terminal, printer, or other output device capable of displaying or producing graphics output. See also graphics output.

graphics stream file ( GSF )

a file containing device-dependent graphics commands from a SAS/GRAPH device driver. This file can be sent to a graphics device or to other software packages.

gray scale

a color-coding scheme that specifies a color in terms of gray components . Gray-scale color codes are commonly used with some laser printers and PostScript devices.

grid request

in the G3GRID procedure, the request specified in a GRID statement that identifies the horizontal variables that identify the x - y plane and one or more z variables for the interpolation.

group variable

a variable in the input data set used to categorize chart variable values into groups.

GSF

See graphics stream file (GSF).
