VisFlow Set Operator
supports set operation between two subsets from a same input table. There are three modes for a set operator: Union, Intersection, and Difference.Connection Order
The Multiple Input Port of the set operator accepts multiple connections.
The first connected edge provides subset S1, the second connected edge provides the subset S2, and so on.
Union
In Union mode, the set operator outputs the union of all input subsets. The visual properties of the data items are merged, when a same data item carries different visual properties from two subsets. In case of a conflict, the latter connected subsets have higher priority.
Intersection
In Intersection mode, the set operator outputs the intersection of all input subsets. The visual properites of the data items in the intersection are merged when they carry different visual properties from multiple subsets. In case of a conflict, the latter connected subsets have higher priority.
Difference
In Intersection mode, the set operator subtracts S2, S3, ... from S1 and outputs the resulting subset.
The visual properties associated with S1 are kept as the visual properties for the output subset.

Mode
Configures the mode of the set operator, from Union, Intersection, and Difference.
