Axis Appearance Features Controlled by the Current Style

The appearance of graphs produced with GTL is always affected by the ODS style that is in effect for the ODS destination. From an axis perspective, the default appearance of the axis line, ticks, tick values, axis label, and grid lines are controlled by predefined style elements.

Style Element	Style Attributes	Values	Controls
GraphAxisLines	TickDisplay	"ACROSS" "INSIDE" "OUTSIDE"	Tick mark location
	LineStyle	Integer: 1 to 49	Axis line pattern
	LineThickness	Dimension	Axis line and tick thickness
	ContrastColor	Color	Axis line and tick color
GraphGridlines	DisplayOpts	"AUTO" "ON" "OFF"	When to display grid lines
	LineStyle	Integer: 1 to 49	Grid line pattern
	LineThickness	Dimension	Grid line thickness
	ContrastColor	Color	Grid line color
GraphLabelText	Color	Color	Axis label text color
	Font	font-specification1	Axis label font
GraphValueText	Color	Color	Axis tick value text color
	Font	font-specification1	Axis tick value font
1A style font-specification includes attributes for FONTFAMILY, FONTWEIGHT, FONTSTYLE, and FONTSIZE.

The following GTL axis options also control the appearance of axis features. When you include these options, the corresponding information from the current style is overridden.

Option	Overrides ...
GRIDDISPLAY=	DisplayOpts attribute of GraphGridLines
GRIDATTRS=	GraphGridLines
LABELATTRS=	GraphLabelText
TICKVALUEATTRS=	GraphValueText
TICKSTYLE=	TickDisplay attribute of GraphAxisLines

Example: Assure that the axis label text appears in bold.

layout overlay / xaxisopts=(labelattrs=(weight=bold))
                 yaxisopts=(labelattrs=(weight=bold));

Example: Display grid lines.

layout overlay / xaxisopts=(griddisplay=on)
                 yaxisopts=(griddisplay=on);

Example: Use a dot pattern for grid lines.

layout overlay / xaxisopts=(griddisplay=on gridattrs=(pattern=dot))
                 yaxisopts=(griddisplay=on gridattrs=(pattern=dot));

Example: Make ticks cross the axes lines.

layout overlay / xaxisopts=(tickstyle=across)
                 yaxisopts=(tickstyle=across);

For all of the preceding examples, you would add similar coding to the X2AXISOPTS= and Y2AXISOPTS= options if the X2 or Y2 axes are used as independent scales. For complete documentation on the axis options that are available, see the SAS Graph Template Language: Reference.
