Get deployment frequency chart data
Get deployment frequency chart data. Engineering insights displays deployment frequency data in the [deployment frequency metric view](https://launchdarkly.com/docs/home/observability/deployments).
### Expanding the chart response
LaunchDarkly supports expanding the chart response to include additional fields.
To expand the response, append the `expand` query parameter and include the following:
* `metrics` includes details on the metrics related to deployment frequency
For example, use `?expand=metrics` to include the `metrics` field in the response. By default, this field is **not** included in the response.
