Using the GROUP Variable

Using the GROUP variable is similar to using the X and Y variables with data system coordinates to position graphics elements in a vertical or horizontal bar chart.

Using the GROUP Variable to Position a Label in a Bar Chart shows how the GROUP variable works with the SUBGROUP and MIDPOINT variables to label the bars of a vertical bar chart.

Using the GROUP Variable to Position a Label in a Bar Chart

The label showing the number of units that were sold in Dallas in the year 1997 is positioned by the values that are assigned to these Annotate variables:

GROUP=YEAR (where YEAR is a variable in the GCHART data set)
MIDPOINT=CITY (where CITY is a variable in the GCHART data set)
SUBGROUP=ITEM (where ITEM is a variable in the GCHART data set).

Functions

You can use the GROUP variable only with the data coordinate systems 1, 2, 7, and 8, and with these functions:

DRAW	PIE	SYMBOL
