Features Supported by Many Plot Statements

Plot Features to Be Displayed

All plots have a standard set of features to display. Most plots can show a different feature set. For example, a HISTOGRAM can display bars that are outlined , filled, or both outlined and filled. A SERIESPLOT displays a line and, if requested, point markers.

DISPLAY=( feature …)

Specifies the plot features to be displayed. Features are plot specific.

Plot Appearance

Depending on the display features, there are options to control the appearance of the features.

MARKERATTRS=( marker-options )	Specifies the symbol, size, color, and weight of markers.
LINEATTRS= ( line-options )	Specifies the pattern, thickness, and color of lines.
TEXTATTRS= ( text-options )	Specifies the text color, font, font size, font weight, and font style.
FILLATTRS= ( fill-options )	Specifies the fill color and transparency.

Plot Transparency

Transparency can be applied to plots that display markers, lines, or filled areas.

DATATRANSPARENCY= number

Specifies the degree of transparency. Default is 0 (fully opaque). 1 is fully transparent.

Plot Identification

In GTL, legends and some dependent plots (for example, MODELBAND) require a reference (association) with a plot. The association is established by 1) naming the plot, and 2) referring to the plot name within the legend or dependent plot statement.

NAME= "string"	Specifies a unique name for a plot in order to associate it with another statement.
LEGENDLABEL= "string"	Specifies a description of a plot to appear in a legend.

layout overlay;
  modelband "cli" / display=(outline)
    outlineattrs=GraphPrediction
    name="predict"
    legendlabel="95% Prediction Limits" ;
  modelband "clm" / display=(fill)
    fillattrs=GraphConfidence
    name="conf"
    legendlabel="95% Confidence Limits" ;

    primary=true;
  regressionplot x=height y=weight /
    alpha=.05 clm="clm" cli="cli";
  discretelegend "predict" "conf" ;
endlayout;

For more information, seeAdding Legends to a Graph.

Labels for Plot Features

Most plots have one or more options that enable you to display descriptive labels or data values for points, lines, bars, or bands.

DATALABEL= column	Specifies a column to label data points in a scatter plot, series plot, needle plot, stepplot, or vectorplot.
DATALABELATTRS= text-properties	Specifies text properties for data labels.
CURVELABEL= "string" \| column	Specifies a string or a string-column to label one or more lines in a REFERENCELINE, DENSITYPLOT, LINEPARM, REGRESSIONPLOT, LOESSPLOT, PBSPLINEPLOT, SERIESPLOT, or STEPPLOT statement.
CURVELABELUPPER= "string" \| column CURVELABELLOWER= "string" \| column	Specifies a string or a string-column to label one or more lines in a BANDPLOT or MODELBAND statement.
CURVELABELATTRS= text-properties	Specifies text properties for curve label(s).
CURVELABELLOCATION= INSIDE \| OUTSIDE	Specifies whether the curve label(s) are located inside or outside the plot area.
CURVELABELPOSITION=	Specifies positioning options for the curve label(s).

layout overlay;
  modelband "cli" / display=(outline)
    outlineattrs=GraphPrediction
    curvelabelupper="95% CLI"
    curvelabellower="95% CLI"
    curvelabelattrs=
    (color=GraphPrediction:Contrastcolor)
    curvelabellocation=outside ;
      
  modelband "clm" / display=(fill)
    fillattrs=GraphConfidence
    curvelabelupper="95% CLM"
    curvelabellower="95% CLM"
    curvelabelattrs=
    (color=GraphConfidence:Color)
    curvelabellocation=outside ;
              
  scatterplot x=height y=weight / 
    primary=true datalabel=sex ;

  regressionplot x=height y=weight /
    alpha=.05 clm="clm" cli="cli"
    curvelabel="Fit"
    curvelabelattrs=
    (color=GraphFit:ContrastColor)
    curvelabellocation=outside ;
endlayout;

Grouping

Many plots support a GROUP= option, which causes visually different markers, lines, or bands to be displayed for each distinct data value of the specified column. You can vary the appearance of group values with the INDEX= option.

GROUP= column	Specifies a group column, always treated as having discrete values. For an example use, see the example for Legend Statements.
INDEX= positive-integer-column	Specifies an integer column that associates each distinct data value to a predefined graphical style element GraphData1, GraphData2, …

For more information on using groups, see Managing Graph Appearance: General Principles.

Axis Assignment

All 2D plots have four potential axes: X, X2, Y, and Y2. You can choose which axes any plot uses. Axis options are typically specified on LAYOUT statement containing the plot.

XAXIS= X \| X2	Specifies whether the plot's X= column is displayed on the X or X2 axis.
YAXIS= Y \| Y2	Specifies whether the plot's Y= column is displayed on the Y or Y2 axis.

For more information, see Managing Axes in an OVERLAY Layout.

Data Tips

Data tips (or tooltips) are text balloons that appear in HTML pages when you move your mouse pointer over a plot component such as a line, marker, or filled area of a graph. To obtain default data tips, simply specify ODS GRAPHICS / IMAGEMAP; as well as the ODS HTML destination. You can customize the data tip information.

ROLENAME= ( role=column …)	Creates additional roles to customize data tips.
TIP= ( role-names )	Specifies which plot roles are used for data tips.
TIPFORMAT=(role=format …)	Specifies a format to be applied to the data for a plot role.
TIPLABEL=( role="string" …)	Specifies a label to be applied to the column for a plot role.

For more information and an example, see Controlling Data Tips.
