Executing a Flag Rule

A flag rule is a set of instructions that tell Windographer to apply a certain flag to certain data columns under certain conditions. When you execute a flag rule, Windographer searches through your dataset for data segments that satisfy those conditions, and applies that flag to those data segments.

A flag rule might, for example, apply the 'Icing' flag to all wind speed sensors whenever a wind direction sensor stops changing for two hours or more while the temperature is below zero degrees Celsius.

You can execute flag rules in the Flag With Rules window.
