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

Interactions: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.

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.

CATEGORYORDER= RESPASC | RESPDESC

specifies the order in which the response values are arranged. Specify one of the following values:

RESPASC

sorts the response values in ascending order.

RESPDESC

sorts the response values in descending order.

Default:By default, the plot is sorted in ascending order based on the category values.

Restrictions:This option takes effect only when the plot statement specifies a response variable and the axis for that variable is numeric. If the axis is not numeric, an error is generated and a message is written to the SAS log.

Uniform scaling and response sorting cannot occur on the same axis. If the UNIFORM= option is used in the SGPLOT statement, the UNIFORM option is ignored for the sorted response axis and a note is generated in the log. The UNIFORM= option is applied to the other axes and groups if requested. Note that the UNIFORM= option can selectively apply scaling to only the X or Y axis

Interaction:If a group variable is specified in the plot statement, the response sort option is ignored and a note is generated in the log. (You can use a BY statement in the procedure if you want to group data.)

Note:If CATEGORYORDER is specified in multiple statements, the procedure sorts by the last statement in which it is specified.

CLUSTERWIDTH= numeric-value

specifies the width of the group clusters as a fraction of the midpoint spacing. Specify a value from 0.0 (narrowest) to 1.0 (widest).

Default:0.8

Interaction:This option is applicable only when the GROUP option is specified, when GROUPDISPLAY=CLUSTER, and when the category axis is discrete.

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.

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

specifies the appearance of the labels in the plot when you use the DATALABEL= option. 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.

Here is an example that specifies a style element: DATALABELATTRS=GraphLabelText

options can be one or more of the following:

COLOR= color

specifies the color of the label characters. 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 Color attribute of the GraphDataText 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.

FAMILY= “font-family”

specifies the font family for the label characters. The SAS ODS styles use TrueType system fonts. For more information, see TrueType Fonts Supplied by SAS in SAS Language Reference: Concepts.

Default:The default font family is specified by the FontFamily attribute of the GraphDataText style element in the current style.

SIZE= n <units>

specifies the font size of the label characters. You can also specify the unit of measurement. The default unit is pixels. For a list of measurement units that are supported, see Units of Measurement.

Default:The default font size is specified by the FontSize attribute of the GraphDataText style element in the current style.

STYLE= ITALIC | NORMAL

specifies whether the label characters are italic (ITALIC) or normal (NORMAL).

Default:The default font style is specified by the FontStyle attribute of the GraphDataText style element in the current style.

WEIGHT= BOLD | NORMAL

specifies whether the label characters are bold (BOLD) or normal (NORMAL).

Default:The default font weight is specified by the FontWeight attribute of the GraphDataText style element in the current style.

Here is an example expression:

DATALABELATTRS=(Color=Green Family=Arial Size=8 Style=Italic Weight=Bold)

Default:The default style element is GraphDataText.

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

DISCRETEOFFSET= numeric-value

specifies an amount to offset all dots from discrete category values. Specify a value from -0.5 (left offset) to +0.5 (right offset).

Default:0.0 (no offset)

Requirement:This option is applicable only when the category axis is discrete.

FREQ= numeric-variable

specifies how many times observations are repeated for computational purposes. 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. 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.

GROUPDISPLAY= CLUSTER | OVERLAY

specifies how to display grouped dots.

CLUSTER

grouped items are drawn adjacent to each other.

OVERLAY

grouped items are drawn at the exact coordinate and might overlap. Each group is represented by unique visual attributes derived from the GraphData1... GraphDatan style elements in the current style.

Default:OVERLAY

Restriction:GROUPDISPLAY=CLUSTER can take effect only when the category axis is discrete. If necessary, use a TYPE=DISCRETE option on the axis statement.

Interaction:This option is ignored unless GROUP= is specified.

GROUPORDER= ASCENDING | DESCENDING | DATA

specifies the ordering of dots within a group.

ASCENDING

displays each group in ascending group value.

DESCENDING

displays each group in descending group value.

DATA

displays each group in data order of the group variable.

Interaction:This option is ignored unless GROUP= is specified.

LEGENDLABEL= “text-string”

specifies the label that identifies the dot 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) is used. If the RESPONSE= option is not used, 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 also specify suboptions to override specific appearance attributes.

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: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. For a list of line patterns, see 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. For a list of measurement units that are supported, see Units of Measurement.

Default:The default line thickness is specified by the LineThickness attribute of the GraphError style element in the current style.

LIMITS= BOTH | LOWER | UPPER

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

Default: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

Interactions: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.

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.

options can be one or more of the following:

COLOR= color

specifies the color of the markers. 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:The default marker size is specified by the MarkerSize attribute of the GraphDataDefault style element in the current style.

SYMBOL= symbol-name

specifies the symbol for the markers. For a list of valid marker symbols, see Marker Symbols.

Default:For ungrouped data, the default marker symbol is specified by the MarkerSymbol attribute of the GraphDataDefault style element in the current style. For grouped data, the default marker symbol is specified by the MarkerSymbol attribute of the GraphData1 ... GraphDatan style elements in the current style.

MISSING

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

NAME= “text-string”

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

Note:The name is case-sensitive. When you refer to the specified name in other statements, you must use the same exact capitalization.

NOSTATLABEL

removes the statistic name from the axis and legend labels.

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:1

RESPONSE= response-variable

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

STAT= FREQ | MEAN | SUM

specifies the statistic for the horizontal axis. Specify one of the following:

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 RESPONSE=, then you can use either the SUM or MEAN statistics.

TRANSPARENCY= numeric-value

specifies the degree of transparency for the plot. 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.

Default:By default, no HTML links are created.

Interactions:This option affects graphics output that is created through the ODS HTML destination only. For more information about ODS destinations, see Specifying a Destination.

This option has no effect unless you also specify IMAGEMAP in the ODS GRAPHICS statement. For more information, see Using the ODS GRAPHICS Statement.

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.

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.
