The Graphics Output Environment

The Graphics Output and Device Display Areas

When SAS/GRAPH produces graphics output, it draws the graphic elements inside an area called the graphics output area. The graphics output area is contained within the device display area. Characteristics of both the graphics output area and the device display area are determined by the values of specific device parameters. In many cases the dimensions of the graphics output area equals those of the device display area. This is particularly true for display devices such as monitors and terminals. Hard-copy devices, such as a printed output, create a margin since the dimensions of the graphics output area are smaller than those of the device's display area.

You can modify some of the characteristics of the graphics output area and the device display area by using graphics options to change the values of the device parameter.

This section describes how you can change the dimensions of the output and display areas, how these changes in dimension affect the output, and the types of units you can specify for your output. For a description of the graphics options and device parameters referred to in this section, see Graphics Options and Device Parameters Dictionary.
