Stages stacked in order, each one a subset of the one above, drawn as a bar whose width is how many survive. Nothing rejoins and nothing enters partway down. Because every stage is nested, the widest fall between two bars is the whole diagnosis, and it is often not the stage you have been working on.

Example

Best when each stage strictly narrows the one before it and you want the largest fall.
