## When to use

Composite charts overlay multiple series of different chart types on a shared x axis. Use them when you want to show a primary metric (typically as a bar) and a secondary related metric (typically as a line), for example, deal count and conversion rate over time.

## Required data shape

* **X axis**: shared by all series.
* **Series**: one or more series, each with its own type (`bar`, `line`, `area`) and y property.

## Configuration

| Setting | What it does                                                                                     |
| ------- | ------------------------------------------------------------------------------------------------ |
| X-axis  | The property shared by every series along the horizontal axis.                                   |
| Series  | One or more value series to plot, each with its own type (bar, line, or area), label, and color. |

## Limitations

* Two series is the sweet spot; three is the upper limit for legibility.
* Pick differing scales carefully. If the secondary metric is much smaller than the primary, use a dual-axis view.
