Value Filter Definition

A value filter which can be used to trigger interactive filter events in a layout of views (e.g. the WebPortal). The node appends a filter definition to the table spec.

Only view nodes downstream of this node can receive interactive filter events.

Note that the filter uses the possible values set on a nominal column's domain as configuration. To ensure the values are reflected and sorted correctly the Domain Calculator and/or Edit Nominal Domain nodes can be used beforehand.

Options

Filter Column
Select the column to apply the filter definition to. The domain of possible values of the column is used to configure the filter.
Default Values
Select the default values to be used for filtering from the possible values of the chosen filter column. If Single Values is selected only the first value in the includes list will be present on the filter.
