Syntax

XSYS='coordinate-system';

coordinate-system

specifies a value that represents a coordinate system. Values can be 1 through 9 and A through C as shown in the following table:

Absolute Systems	Relative Systems	Coordinate System Units
1	7	percentage of data area
2	8	data values
3	9	percentage of graphics output area
4	A	cell in graphics output area
5	B	percentage of procedure output area
6	C	cell in procedure output area

These values are also used by the HSYS and YSYS variables. See Coordinate Systems for a description of the areas and coordinate systems.

Functions

You can use the XSYS variable with these functions:

ARROW	LABEL	POINT
BAR	MOVE	POLY
DRAW	PIE	POLYCONT
FRAME	PIECNTR	SYMBOL

The behavior of the XSYS variable is function-dependent for the following functions:.

BAR, DRAW

The coordinate system that you specify with the XSYS variable affects how the function interprets the value of the X or XC variable. If XC is used, XSYS='2' must also be used.

FRAME

The XSYS and YSYS variables define the area enclosed by the frame. To draw a frame that encloses the axis area, use XSYS='1' and YSYS='1', as shown in the following figure.

Frame Created When XSYS='1' and YSYS='1'

[Frame Created When XSYS='1' and YSYS='1']

To draw a frame that encloses the entire graphics output area, specify XSYS='3' and YSYS='3', as shown in the following figure.

Frame Created When XSYS='3' and YSYS='3'

[Frame Created When XSYS='3' and YSYS='3']

To limit the size of the frame to the size of the procedure output area, specify a value of 5 for XSYS and YSYS.

Note that the values of XSYS and YSYS can differ. You can specify a frame that occupies the entire width of the graphics output area and only the vertical width of the procedure output area by specifying XSYS='3' and YSYS='5', as shown in the following figure.

Frame Created When XSYS='3' and YSYS='5'

[Frame Created When XSYS='3' and YSYS='5']

Details

The coordinate system that you specify with the XSYS variable affects how the function interprets the value of the X or XC variable.

Note: Not all coordinate systems can be used with all Annotate variables. For any restrictions, see the individual variables in this section. [cautionend]
