About the Filter node
The Filter node (BqlFilter Node) filters a series of data using a bql predicate expression. For example, you can use an expression
such as:
value > 80 to show only values greater than 80 or timestamp in bqltime.yesterday to limit values to those recorded on the previous day.
To use the FilterNode component, drag it from the Series Transform palette onto the Wire Sheet view and connect a HistorySource output to the Filter Inputs slot. Double-click on the Filter component in the Wire Sheet view and use the Filter window to create a custom bql query.

Connect the output from the Filter node to another SeriesTransform node input or directly to a Terminal Node input as desired.

Resolve the graph and check that the table displays the expected time values as defined by the query set in the Filter window.
