Additional nodes may be created by third-party developers using the series transform API. However, with NiagaraAX-3.7, there are seven individual objects provided on the seriesTransform palette. The following components can be thought of as comprising four general categories of Series Transform objects:
-
Container (Transform Graph node)
The TransformGraph object holds all the other graph nodes and has a action that you use to generate the data transformation after you have configured all the nodes as desired.
-
Source (HistorySource node)
The HistorySource node is the single object available for identifying the source data for your tranformation.
-
Terminal (Terminal node)
There is one terminal node that is the final node of any transform graph. Each Transform Graph must have one and only one terminal node.
-
Transforms (Transform nodes)
Transform nodes provided on the palette include the Aggregate, Composite, Rollup, and Scale nodes.
By adding components from the seriesTransform palette onto a Transform Graph wiresheet view, you can create a static definition of how run-time data is transformed into a new single-output set of information. The transform graph is created using HistorySource nodes, one or more transform nodes, and a single terminal node. By configuring the data schema of each transformation you design how the data flows from one transformation node to the next.
All graph nodes must be contained by a Transform Graph container. All nodes within the Transform Graph container must be uniquely
named.
Each of the graph nodes described in the following sections includes a special popup editor that displays when clicking the graph node component in the wiresheet view. The Property Sheet view is still accessible, but must be selected from the workbench View Selector.
