# Aggregators

Aggregators compute derived values from a series. In Elixir they live on `Trifle.Stats.Series` and accept a dot-separated `path` into the values map. They return a list of computed values (one per slice).

> Note: `path` is a list of keys joined by dot. Example: `"orders.shipped.count"` maps to `%{"orders" => %{"shipped" => %{"count" => ...}}}`.
