The SGPLOT Procedure

VLINE Statement

Creates a vertical line plot (the line is horizontal). You can use the VLINE statement with the VBAR statement to create a bar-line chart.
Featured in: Creating a Bar-Line Chart
Interaction: The VLINE statement can be combined only with other categorization plot statements in the SGPLOT procedure. See Plot Content.


Syntax

VLINE category-variable < / option(s)>;

option(s) can be one or more options from the following categories:

Required Arguments

category-variable

specifies the variable that classifies the observations into distinct subsets.

Options

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 if you do not specify LIMITSTAT=CLM.

If your plot is overlaid with other summary plots, then the first ALPHA value that you specify is used for all of the plots.
BREAK

creates a break in the line for each missing value.

CURVELABEL <="text-string">

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

CURVELABELPOS= MIN | MAX | START | END

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

MIN

places the curve label at the minimum value for the response axis.

MAX

places the curve label at the maximum value for the response axis.

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
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 calculated response are used for the data labels.

FREQ= numeric-variable

specifies that each observation is repeated n times for computational purposes, where n is the value of the numeric variable. If n is not an integer, then it is truncated to an integer. If n is less than 1 or missing, then it is excluded from the analysis.

Interaction: If your plot is overlaid with other categorization plots, then the first FREQ variable that you specified is used for all of the plots.
GROUP= variable

specifies a variable that is used to group the data. A separate plot is created for each unique value of the grouping variable. The plot elements for each group value are automatically distinguished by different visual attributes.

Interaction: If you specify more than one categorization plot statement, then all of the plots must specify the same GROUP variable. If you do not specify the same GROUP= option for all of the categorization plots, then the GROUP= option has no effect.
LEGENDLABEL= "text-string"

specifies the label that identifies the line plot in the legend. By default, the label of the response variable is used. If there is no response variable label, then the name of the response variable and the computed statistic (SUM or MEAN) are used. If you do not specify a response variable, then the legend label is "Frequency".

Interaction: The LEGENDLABEL= option has no effect if you also specify the GROUP= option in the same plot statement.
LIMITATTRS= style-element <(options)> | (options)

specifies the appearance of the limit lines 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 additionally specify suboptions to override specific appearance attributes.

options can be one or more of the following:

COLOR= color

specifies the color of the line. For more information about specifying colors, see SAS/GRAPH Colors and Images in the SAS/GRAPH: Reference, Second Edition.

Default: The default color is specified by the ContrastColor attribute of the GraphError style element in the current style.
PATTERN= line-pattern

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

Default: The default line pattern is specified by the LineStyle attribute of the GraphError style element 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. See Units of Measurement for a list of the measurement units that are supported.

Default: The default line thickness is specified by the LineThickness attribute of the GraphError style element in the current style.
Restriction: This option is available with SAS 9.2 Phase 2 and later.
LIMITS= BOTH | LOWER | UPPER

adds limit lines to the plot. Specify one of the following values:

BOTH

adds lower and upper limit lines to the plot.

LOWER

adds lower limit lines to the plot.

UPPER

adds upper limit lines to the plot.

By default, no limit lines are displayed. However, if you specify the LIMITSTAT= option, then the default is BOTH.

Note:   Limit lines are displayed only when you specify STAT= MEAN.  [cautionend]

LIMITSTAT= CLM | STDDEV | STDERR

specifies the statistic for the limit lines. Specify one of the following statistics:

CLM

confidence limits

STDDEV

standard deviation

STDERR

standard error

Default: CLM
Interaction: If you specify the LIMITSTAT= option, then the default value for the LIMITS= option is BOTH.
LINEATTRS= style-element <(options)> | (options)

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

options can be one or more of the following:

COLOR= color

specifies the color of the line. For more information about specifying colors, see SAS/GRAPH Colors and Images in the SAS/GRAPH: Reference, Second Edition.

Default: For ungrouped data, the default color is specified by the ContrastColor attribute of the GraphDataDefault 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. See Line Patterns for a list of line patterns.

Default: For ungrouped data, the default line pattern is specified by the LineStyle attribute of the GraphDataDefault 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. See Units of Measurement for a list of the measurement units that are supported.

Default: For ungrouped data, the default line thickness is specified by the LineThickness attribute of the GraphDataDefault 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.
MARKERATTRS= style-element <(options)> | (options)

specifies the appearance of the markers in the plot. This option has no effect unless you also specify the MARKERS option. You can specify the appearance by using a style element or by using suboptions. If you specify a style element, you can additionally specify suboptions to override specific appearance attributes.

options can be one or more of the following:

COLOR= color

specifies the color of the markers. For more information about specifying colors, see SAS/GRAPH Colors and Images in the SAS/GRAPH: Reference, Second Edition.

For grouped data, the default marker symbol is specified by the MarkerSymbol attribute of the GraphData1 ... GraphDatan style elements in the current style.
MARKERS

adds markers to the plot.

MISSING

processes missing values as a valid category value and creates a line for it.

NAME= "text-string"

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

STAT= FREQ | MEAN | SUM

specifies the statistic for the vertical axis. Specify one of the following statistics:

FREQ

the frequencies for the category variable. This is the default value when you do not specify the RESPONSE= option.

MEAN

the mean of the response variable.

SUM

the sum of the response variable. This is the default value when you specify the RESPONSE= option.

If you do not specify the RESPONSE= option, then only FREQ can be used. If you specify RESPONSE=, then you can use either SUM or MEAN.
