# Extended result

The extended result object lets you return:

## Option

The option is the chart configuration in the JSON format described in the [Charts Functions](/docs/plugins/volkovlabs-echarts-panel/latest/charts-function/).

## Unsubscribe

The unsubscribe section allows the addition of JavaScript code which is executed before the object is destroyed.

One of the use cases relates to unsubscription from [Grafana events using an event bus](/docs/plugins/volkovlabs-echarts-panel/latest/features/grafana-events/).
