The formula bar offers an intelligent way to build formulas for Klips (in the Klip Editor or when modelling a data source you'll use to build a Klip) and in PowerMetrics (when modelling a data source or editing a data feed you'll use to build a custom metric).
You can type a formula directly in the formula bar or select from a list of functions. When you start typing a function name in the formula bar, a list of functions filtered by the letter you entered is displayed. Online help with examples and parameters automatically pops up for each function.
