Annotations let you extract data from a data source and use it to annotate a dashboard.
Annotations support was added in v1.0.1. If you can't select the JSON API data source from the list of data sources, try updating to a more recent version.
To use the JSON API data source for annotations, follow the instructions on Querying other data sources. Make sure to select the JSON API from the list of data sources.
Configure a query with at least two fields:
- A String field for the annotation text
- A Time field for the annotation time
If you want to add titles or tags to the annotations, you can add additional Fields with the appropriate types.
For more information on how to configure a query, refer to Query editor.
