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 specify the CLI or CLM option (or both).

CLIATTRS = style-element | (CLILINEATTRS= style-element <(options)> | (options))

specifies the appearance of the individual value prediction limits by using an ODS style element or by specifying attributes for the outlines. The outline attributes can be the following:

CLILINEATTRS= 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.

Default:For ungrouped data, the default line pattern is specified by the LineStyle attribute of the GraphPredictionLimits 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.

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

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;

   (COLOR=Green PATTERN= ShortDash)); 
run;

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

Default:END

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

The START and END suboptions take effect only when CURVELABELLOC=INSIDE.

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.
