To help you visualize Multirate Dataflow, LabVIEW provides the ability to display the sample counts of each node terminal on a Multirate diagram.
The sample count for each input terminal represents the number of data samples that input requires before the node can execute. The sample count for each output terminal represents the number of data samples that the node returns. You can configure the sample counts for many nodes.
As the previous example illustrates, displaying sample counts is useful for visualizing the flow of data streams and making sure each node operates on the correct number of data samples.
