# ChartAutomationOwners [Integration guide](https://docs.lumencharts.com/charting-library/reference/compatibility) · [Reference index](https://docs.lumencharts.com/charting-library/api/) Public contract reference. This declaration describes types and callback shapes; availability is constrained by the linked integration guide and the runtime capability. Legacy product-specific fields are not a promise of implementation. Native owners the caller already holds for this chart (for example from `createDrawingCommands` or `createDrawingDocument`). A supplied owner is used as-is and is never destroyed by the session; the caller keeps ownership. ## drawings {#drawings} ```ts drawings?: ChartDrawingApi; ``` Use the type signature above and the integration guide for the owning capability. ## studies {#studies} ```ts studies?: ChartStudyApi; ``` Use the type signature above and the integration guide for the owning capability. ## settings {#settings} ```ts settings?: ChartSettingsApi; ``` Use the type signature above and the integration guide for the owning capability. --- Documentation page: https://docs.lumencharts.com/charting-library/api/ChartAutomationOwners
