PowerBuilder populates the Value drop-down list. The list includes the names of all the retrieved columns as well as the following aggregate functions:
Count for all non-numeric columns
Sum for all numeric columns
Select an item from the drop-down list or type an expression (in the Properties view). For example, if you want to graph the sum of units sold, you can specify:
sum(units for graph)
To graph 110 percent of the sum of units sold, you can specify:
sum(units*1.1 for graph)
