XMAX

XMAX



Specifies the width of the addressable graphics display area; affects the horizontal resolution of the device and the horizontal dimension of the graphics output area.

Used in: GOPTIONS statement; GDEVICE procedure; GDEVICE Detail window
Restriction: Ignored by default display drivers and host printing drivers
See also: HSIZE, PAPERSIZE, XPIXELS

Syntax

XMAX=width <IN | CM | PT>

width
is a positive number that may be followed by a unit specification, either IN for inches (default), or CM for centimeters, or PT for points. If you do not specify XMAX, a default width is searched for in this order:
  1. the width specification on an OPTIONS PAPERSIZE setting

  2. XMAX in the device entry catalog.

If XMAX=0, default behavior is used. If both XMAX and PAPERSIZE have been specified on GOPTIONS, the last request is used.


Details

Like the XPIXELS device parameter, XMAX controls the width of the display area, but the width is in inches, centimeters, or points rather than pixels. Typically, you might use XMAX to change the width of the display area for a hardcopy device.

SAS/GRAPH uses the value of XMAX in calculating the horizontal resolution of the device:

x-resolution = XPIXELS / XMAX

However, changing XMAX does not necessarily change the resolution:

XMAX also affects the value of HSIZE, which controls the horizontal dimension of the graphics output area.

To permanently change the value of the XMAX device parameter in the device entry, use the GDEVICE procedure. This can change the resolution.

To temporarily change the size of the display and the resolution of the device for the current graph or for the duration of your SAS session, use XMAX= and XPIXELS= in the GOPTIONS statement.

To reset the value of XMAX to the default, specify XMAX=0. To return to the default resolution for the device, specify both XMAX=0 and XPIXELS=0.

See Procedure Output and the Graphics Output Area for more information.
