Previewing Data in Nodes

To ensure that data is being changed in the way you expect as you build a stream, you could run your data through a Table node at each significant step. To save you from having to do this, you can generate a preview from each node that displays a sample of the data that will be created, thereby reducing the time it takes to build each node.

For nodes upstream of a model nugget, the preview shows the input fields; for a model nugget or nodes downstream of the nugget (except terminal nodes), the preview shows input and generated fields.

The default number of rows displayed is 10; however, you can change this in the stream properties. See the topic Setting general options for streams for more information.

From the Generate menu, you can create several types of nodes.

Note: When previewing data generated by this node, all property changes will be applied to this node and cannot be cancelled (the same behavior as clicking Apply).
