SUBGROUP Variable



Positions graphics elements within subgrouped bars of a vertical or horizontal bar chart produced by the GCHART procedure.
Type: Numeric or character; must match the type of the SUBGROUP variable used in the GCHART procedure.
Length: Should match the length of the SUBGROUP= variable in the GCHART procedure.
Default: none
Restriction: The bar charts must have been produced using the SUBGROUP= option.

Syntax

SUBGROUP=subgroup-value;

subgroup-value

references value(s) of the SUBGROUP= variable in the GCHART procedure either as a variable name or as an explicit data value. Subgroup-value can have one of the following forms:

subgroup-variable

the name of a subgroup variable.

subgroup-data-value

a specific numeric data value.

subgroup-data-value

a specific character data value.

Generally, specify a variable name if you want to annotate all of the bars in a horizontal or vertical bar chart. To annotate a bar chart for a specific value of the SUBGROUP variable, specify a specific value.

Functions

You can use the SUBGROUP variable only with the data coordinate system 1, 2, 7, or 8, and with these functions:

BAR PIE POLY
DRAW PIECNTR POLYCONT
LABEL POINT SYMBOL
MOVE

Details

Using the SUBGROUP variable is similar to using the X and Y variables with data system coordinates to position the graphics elements in subgroup segments in vertical and horizontal bar charts.For example, in a vertical bar chart that produces a bar for each city in a data set, you can easily label the subgroups in each bar by setting subgroup-variable to the GCHART variable by which the bar is being subgrouped. This variable provides the y coordinate of the label (so don't specify a competing value for y, but instead specify y=. or y=y).

The MIDPOINT variable works well with the SUBGROUP variable to provide the x coordinate. In this example, if you set the MIDPOINT variable to the GCHART variable that contains the names of the cities, the MIDPOINT variable provides your x coordinate. Rather than providing the X and Y variables, you would use the SUBGROUP and MIDPOINT variables. Using the SUBGROUP Variable to Position a Label in a Bar Chart shows how the SUBGROUP variable works with the MIDPOINT variable to label the bars of a vertical bar chart.
