A rotation variable is a visual variable that defines the rotation of a symbol based on a numeric data value returned from a field or expression. This value is typically used to rotate symbols that indicate directionality such as:
- wind direction
- traffic flow
Rotation visual variables differ from other visual variables in that they only require a data value without requiring stops. Rotation visual variables require the following:
- A reference to a data value either from a field name, or an Arcade expression.
- An optional rotation type, indicating a geometric or arithmetic rotation.
