The SGPANEL Procedure

HBAR Statement

Creates a bar chart that summarizes the values of a category variable.

Interaction:	The HBAR statement can be combined only with other categorization plot statements in the SGPANEL procedure. See Plot Content.
Featured in:	Creating a Panel of Bar Charts

Syntax

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

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

Bar options:

	ALPHA= numeric-value
	BARWIDTH= numeric-value
	DATALABEL
	FILL \| NOFILL
	FILLATTRS= style-element \| (options)
	FREQ= numeric-variable
	LIMITATTRS= style-element <(options)> \| (options)
	LIMITS= BOTH \| LOWER \| UPPER
	LIMITSTAT= CLM \| STDDEV \| STDERR
	MISSING
	NOSTATLABEL
	NUMSTD= n
	OUTLINE \| NOOUTLINE
	RESPONSE= response-variable
	STAT= FREQ \| MEAN \| SUM
	URL= variable
	WEIGHT= numeric-variable

Plot options:

GROUP= variable

LEGENDLABEL= "text-string"

NAME= "text-string"

TRANSPARENCY= numeric-value

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 categorization plots, then the first ALPHA value that you specify is used for all of the plots.

BARWIDTH= numeric-value

specifies the width of the bars as a ratio of the maximum possible width. The maximum width is equal to the space between the center of each bar and the centers of the adjacent bars. Specify a value between .1 and 1.

For example, if you specify a width of 1, then there is no distance between the bars. If you specify a value of .5, then the width of the bars is equal to the space between the bars.

Default:

DATALABEL

adds data labels for bars. The values of the response variable appear at the end of the bars.

Restriction:

This option is available with SAS 9.2 Phase 2 and later.

FILL | NOFILL

specifies whether the bars are filled. The FILL option shows the fill color for the bars. The NOFILL option hides the fill color for the bars.

Default:

FILL

FILLATTRS= style-element | (COLOR= color)

specifies the appearance of the fill for the bars. You can specify the color of the fill by using a style element or by using the COLOR= suboption. For more information about specifying colors, see SAS/GRAPH Colors and Images in the SAS/GRAPH: Reference, Second Edition.

Note: This option has no effect if you specify the NOFILL option. [cautionend]

Default:

For ungrouped data, the default color is specified by the Color attribute of the GraphDataDefault style element in the current style.

For grouped data, the default color is specified by the Color attribute of the GraphData1 ... GraphDatan style elements in the current style.

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 grouping variable.

LEGENDLABEL= "text-string"

specifies the label that identifies the bar chart in the legend. By default, the label of the RESPONSE= variable is used. If there is no response variable label, the name of the response variable and the computed statistic (SUM or MEAN) is used. If the RESPONSE= option is not used, 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

specifies which limit lines to display. Limits are displayed as heavier line segments with a serif at the end extending from each bar. Upper limits extend to the right of the bar and lower limits extend to the left of the bar. By default, no limits are displayed unless you specify either the LIMITS= or LIMITSTAT= option. If you specify the LIMITSTAT= option only, then LIMITS=BOTH is the default. 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.

Interaction:

Limit lines are displayed only when you specify STAT= MEAN.

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 only, then the default value for the LIMITS= option is BOTH. Limits lines are displayed only when you specify STAT=MEAN.

MISSING

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

NAME= "text-string"

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

NOSTATLABEL

removes the statistic name from the axis and legend labels.

Restriction:

This option is available with SAS 9.2 Phase 2 and later.

NUMSTD= n

specifies the number of standard units for the limit lines, when you specify LIMITSTAT= STDDEV or LIMITSTAT= STDERR. You can specify any positive number, including decimals.

Default:

OUTLINE | NOOUTLINE

specifies whether the bars have outlines. The OUTLINE option shows the outlines. The NOOUTLINE option hides the outlines.

Default:

OUTLINE

RESPONSE= response-variable

specifies a numeric response variable for the plot. The summarized values of the response variable are displayed on the horizontal axis.

STAT= FREQ | MEAN | SUM

specifies the statistic for the horizontal 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 the FREQ statistic can be used. If you specify the RESPONSE= option, then you can use either the SUM or MEAN statistics.

TRANSPARENCY= numeric-value

specifies the degree of transparency for the bars and limits, if displayed. Specify a value from 0.0 (completely opaque) to 1.0 (completely transparent).

Default:

0.0

URL= character-variable

specifies a character variable that contains URLs for web pages to be displayed when parts of the plot are selected within an HTML page.

Interaction:	This option affects graphics output that is created through the ODS HTML destination only. This option has no effect unless you also specify IMAGEMAP in the ODS GRAPHICS statement.
Default:	By default, no HTML links are created.

WEIGHT= numeric-variable

specifies that 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.

Interaction:

If your plot is overlaid with other categorization plots, then the first WEIGHT variable that you specified is used for all of the plots.
