Pareto Pyramid / Paired Pareto Chart

The Pareto Pyramid is a variant on the Pareto Chart which shows two charts together. This is typically used in a 'before and after' scenario.

One chart is in the standard sorted order, and the other shows clearly how things have changed.

The Paired Pareto chart is another variant of the same thing, simply with bars for the same category next to one another.
