Summary
Select a statistical summary function for the graphic element. The result of the statistic
determines the position of the graphic elements on the Y-axis. In a 2-D chart, the statistic is
calculated for each value on the X-axis. In a 3-D chart, it is calculated for the intersection of
values on the X-axis and Z-axis.
Two types of statistical summary functions are
available. The distinction is important because it determines whether you need to specify a
Value variable.
Functions that do not require a value variable. Functions that do not
require a variable. All count and percentage statistics are in this category. These statistics are
available when the Value variable is not defined.
Functions that do require a value variable. Functions that do require
a Value variable. For example, the Mean function requires
a variable on which the mean is calculated. These statistics are available when the
Value variable is not defined.

variable, is selected. Select a variable to serve as the value.
