SUBGROUP Variable |
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-variable | the name of a subgroup variable. |
subgroup-data-value | a specific numeric data value. |
subgroup-data-value | a specific character data 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.
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.

The label showing the number of printers sold in Atlanta is positioned by the values that are assigned to these Annotate variables:
