Segment Attributes

A set of attributes is initialized for each graphics segment. These attributes are color, line style, line thickness, fill pattern, font, character height, and aspect ratio. You can change any of these attributes for a graphics segment by using the GSET command. Some IML graphics commands take optional attribute arguments. The values of these arguments affect only the graphics output associated with the call.

The IML graphics subsystem uses the same conventions that SAS/GRAPH software uses in setting the default attributes. It also uses the options set in the GOPTIONS statement when applicable. The SAS/IML default values for the GSET command are given by their corresponding GOPTIONS default values. To change the default, you need to issue a GOPTIONS statement. The GOPTIONS statement can also be used to set graphics options not available through the GSET command (for example, the ROTATE option).

For more information about GOPTIONS, refer to the chapter on the GOPTIONS statement in SAS/GRAPH Software: Reference.
