Managing Labels & Units in your Sankey DiagramsShow Totals in Node Labels? Showing Node totals in labels can make the diagram nicely specific, but doing so can require a lot of horizontal room to keep the labels from intruding on other nodes. You have the option of leaving out the specific totals by unchecking the “Show Node totals as part of labels” checkbox.

Sankey diagrams can be arranged in a multitude of ways. If you use a consistent layout for presenting your data's story, and if you produce diagrams using the same scale, then it becomes possible to compare them usefully.
