SAS 9.4 Graph Template Language, 3rd Edition

Here is example output.

Other statements such as DENSITYPLOT, REGRESSIONPLOT, LOESSPLOT,

PBSPLINEPLOT, MODELBAND, REFERENCELINE, and DROPLINE are

"specialized" in the sense that their default line appearance is governed by other style

elements such as GraphFit, GraphConfidence, GraphPrediction, GraphReference, or

some other specialized style element. When these statements are used in conjunction

with the "non-specialized" plot statements, there are differences in appearance.

Plots That Support Grouped Data

The GROUP= column option is used to plot data when a classification or grouping

variable is available. Plots that support the GROUP= option include the following:

AXISTABLE HEATMAPPARM PIECHART

BANDPLOT HIGHLOWPLOT POLYGONPLOT

BARCHART LINECHART REGRESSIONPLOT

BARCHARTPARM LINEPARM SCATTERPLOT

BOXPLOT LOESSPLOT SCATTERPLOTMATRIX

BOXPLOTPARM MODELBAND SERIESPLOT

BUBBLEPLOT MOSAICPLOTPARM STEPPLOT

ELLIPSEPARM NEEDLEPLOT VECTORPLOT

FRINGEPLOT PBSPLINEPLOT WATERFALLCHART

Starting with the second maintenance release of SAS 9.4, the DENSITYPLOT,

ELLIPSE, and HISTOGRAM statements also support the GROUP= option.

Using the Default Appearance for Grouped Data

By default, the GROUP= option automatically uses the style elements GraphData1–

GraphDataN for the presentation of each unique group value. Consider the following

template for a series plot that displays grouped data.

Example Code 23.1 Template for a Grouped Series Plot

proc template;

define statgraph groupedseries;

begingraph;

entrytitle "Tech Stocks 2002-2004";

entryfootnote halign=left "Source: SASHELP.STOCKS";

layout overlay;

seriesplot x=date y=close / group=stock name="series"

lineattrs=(thickness=2);

discretelegend "series";

endlayout;

endgraph;

end;

run;

Executing this template with the default ODS style HTMLBLUE generates the following

output.

proc sgrender data=sashelp.stocks template=groupedseries;

where date between "1jan02"d and "31dec04"d;

run;

Attributes such as line color and pattern are used to display the group values. The

attributes are defined by the GraphData1–GraphDataN style elements for the style that is

in effect. The attributes are rotated for each group values as described in “Attribute

Rotation Patterns” on page 478. In the previous example, there are three unique values

of column Stock in the Sashelp.Stocks data set: IBM, Intel, and Microsoft. The line

colors and line patterns from the GraphData1–GraphData3 style elements of the

HTMLBLUE style are used for each of the three group values. Because the

HTMLBLUE style defines the AttrPriority="COLOR" style attribute, the color-priority

attribute rotation pattern is used. The ContrastColor attribute specifies the line color, and

the LineType attribute specifies the line pattern. See Appendix 2, “Graph Style Elements

Controlling the Appearance of Grouped Data 453

Used by ODS Graphics,” on page 569 for information about the GTL style elements and

attributes. See “Attribute Rotation Patterns” on page 478 for information about how the

style attributes are rotated for group values.

The colors and patterns are assigned to the values in the order in which they occur in the

Sashelp.Stocks data set. In this case, GraphData1 is assigned to IBM, GraphData2 is

assigned to Intel, and GraphData3 is assigned to Microsoft. Other attributes such as fill

color, fill pattern, and marker color that are used in other plot types are assigned in a

similar manner. Here are some additional examples of the default grouped data

appearance for other plot types. All of the plots in these examples use the HTMLBLUE

style.

To specify different colors and patterns that you can specify a different ODS style or you

can create a custom style. For information about creating custom styles, see “Using

Custom Styles to Control the Appearance of Grouped Data” on page 455. For many
