Optional Arguments

ALPHA= numeric-value

specifies the confidence level for the confidence limits. Specify a number between 0.00 (100% confidence) and 1.00 (0% confidence).

Default:.05

Interaction:This option has no effect unless you also specify the CLM option.

ATTRID= variable

specifies the value of the ID variable in an attribute map data set. You specify this option only if you are using an attribute map to control visual attributes of the graph. For more information, see Using SG Attribute Maps to Control Visual Attributes.

CLM <= “text-string”>

creates confidence limits. The optional text string overrides the default legend label for the confidence limit.

CLMATTRS = style-element | (CLMAttributeOptions )

specifies the appearance of the mean value confidence limits by using an ODS style element or by specifying fill and line attributes. CLMAttributeOptions can be one or both of the following:

CLMFILLATTRS=style-element | (COLOR= color)

You can specify the color of the fill by using a style element or by using the COLOR= suboption. You can specify colors using the same color schemes that are supported by SAS/GRAPH software. For more information, see Color-Naming Schemes in SAS/GRAPH: Reference.

CLMLINEATTRS= style-element <(options)> | (options)

You can specify the appearance of the outline by using a style element or by using suboptions. If you specify a style element, then you can also specify suboptions to override specific appearance attributes.

The confidence limits have no outlines by default (for most styles). To make the outlines appear, you can change the DISPLAYOPTS in the GRAPHBAND style element. Then you can specify attributes for the outlines. The following code provides an example.

proc template;
  define style MyStyleDefault;
  parent=Styles.Default;
  style GraphBand from GraphBand /
      DisplayOpts = "Fill outline";
  end; 
run;

ods listing style= MyStyleDefault;
proc sgplot data=sashelp.class;
  reg x=height y=weight / CLM
  CLMATTRS=(CLMLINEATTRS= 
   (COLOR=Green PATTERN= ShortDash)); 
run;

The CLMLINEATTRS= options can be one or more of the following:

COLOR= color

specifies the color of the line. You can specify colors using the same color schemes that are supported by SAS/GRAPH software. For more information, see Color-Naming Schemes in SAS/GRAPH: Reference.

Default:For ungrouped data, the default color is specified by the ContrastColor attribute of the GraphConfidence style element in the current style. For grouped data, the default color is specified by the ContrastColor attribute of the GraphData1 ... GraphDatan style elements in the current style.

PATTERN= line-pattern

specifies the line pattern for the line. You can reference SAS patterns by number or by name. For a list of line patterns, see Line Patterns.

Default:For ungrouped data, the default line pattern is specified by the LineStyle attribute of the GraphConfidence style element in the current style. For grouped data, the default line pattern is specified by the LineStyle attribute of the GraphData1 ... GraphDatan style elements in the current style.

THICKNESS= n <units>

specifies the thickness of the line. You can also specify the unit of measure. The default unit is pixels. For a list of measurement units that are supported, see Units of Measurement.

Default:For ungrouped data, the default line thickness is specified by the LineThickness attribute of the GraphConfidence style element in the current style. For grouped data, the default line thickness is specified by the LineThickness attribute of the GraphData1 ... GraphDatan style elements in the current style.

Interaction:This suboption has no effect unless you change the display options in the style element to display outlines. See the preceding code example.

Default:The default appearance of the confidence limits is specified by the GraphConfidence style element in the current style.

Interaction:The CLMATTRS = option has no effect unless you also specify the CLM option.

CLMTRANSPARENCY= numeric-value

specifies the degree of transparency for the confidence limits. Specify a value from 0.0 (completely opaque) to 1.0 (completely transparent).

Default:0.0

Interaction:This option takes effect only if you also specify the CLM option.

CURVELABEL <=“text-string”>

adds a label for the curve. You can also specify the label text. If you do not specify a label, the label from the Y variable is used.

CURVELABELPOS= MIN | MAX | START | END

specifies the location of the curve label. Specify one of the following values:

MIN

places the label at the part of the curve closest to the minimum X axis value.

MAX

places the label at the part of the curve closest to the maximum X axis value.

START

places the curve label at the first point on the curve.

END

places the curve label at the last point on the curve.

Default:END

Interaction:This option has no effect unless the CURVELABEL option is also specified.

DATALABEL <= variable>

displays a label for each data point. If you specify a variable, then the values of that variable are used for the data labels. If you do not specify a variable, then the values of the Y variable are used for the data labels.

Interaction:This option has no effect if you also specify the NOMARKERS option.

DEGREE= 1 | 2

specifies the degree of the local polynomials to use for each local regression. 1 specifies a linear fit and 2 specifies a quadratic fit.

Default:1

GROUP= variable

specifies a classification variable to divide the values into groups. A separate plot is created for each unique value of the classification variable.

Interaction:If you specify the GROUP= option in multiple fit plot statements, then the first GROUP= variable is used for all of the fit plots that specify GROUP=.

INTERPOLATION= CUBIC | LINEAR

specifies the degree of the interpolating polynomials that are used for blending local polynomial fits at the kd tree vertices.

Default:CUBIC

LEGENDLABEL= “text-string”

specifies a label that identifies the fit line in the legend. By default, the label “Loess” is used, along with the value of the SMOOTH= option if specified.

LINEATTRS= style-element <(options)> | (options)

specifies the appearance of the fit curve. You can specify the appearance by using a style element or by using suboptions. If you specify a style element, you can also specify suboptions to override specific appearance attributes.

options can be one or more of the following:

COLOR= color

For grouped data, the default line thickness is specified by the LineThickness attribute of the GraphData1 ... GraphDatan style elements in the current style.

MARKERATTRS= style-element <(options)> | (options)

specifies the appearance of the markers in the plot. You can specify the appearance by using a style element or by using suboptions. If you specify a style element, you can also specify suboptions to override specific appearance attributes.

Default:201

NAME= “text-string”

specifies a name for the plot. You can use the name to refer to this plot in other statements.

NOLEGFIT

hides the legend entry for the fit line.

NOMARKERS

removes the scatter markers from the plot.

REWEIGHT= n

specifies the number of iterative reweighting steps to apply to the data.

Default:0

Interaction:This option has no affect if you do not specify the WEIGHT option.

SMOOTH= numeric-value

specifies a smoothing parameter value. If you do not specify this option, a smoothing value is determined automatically.

WEIGHT= numeric-variable

specifies how observations are weighted. Each observation is weighted by a factor of w for computational purposes, where w is the value of the numeric variable. w can be any numeric value. If w is 0, negative or missing, then that observation is excluded from the analysis.
