== Region Maps
|
|
|
|
Region maps are thematic maps in which boundary vector shapes are colored using a gradient:
|
|
higher intensity colors indicate larger values, and lower intensity colors indicate smaller values.
|
|
These are also known as choropleth maps.

|
=== Configuration
|
|
|
|
To create a region map, you configure an inner join that joins the result of an Elasticsearch terms aggregation
|
|
and a reference vector file based on a shared key.

|
===== Layer Settings
|
|
- *Vector map*: select from a list of vector maps. This list includes the maps that are hosted by the © https://www.elastic.co/elastic-maps-service[Elastic Maps Service],
|
|
as well as your self-hosted layers that are configured in the *config/kibana.yml* file. To learn more about how to configure Kibana
|
|
to make self-hosted layers available, see the <<regionmap-settings,regionmap settings>> documentation. You can also explore and preview vector layers available in Elastic Maps Service at https://maps.elastic.co[https://maps.elastic.co].
|
|
- *Join field*: this is the property from the selected vector map that will be used to join on the terms in your terms-aggregation.
|
|
When terms cannot be joined to any of the shapes in the vector layer because there is no exact match in the vector layer, Kibana will display a warning.
|
|
To turn of these warnings, go to *Management/Kibana/Advanced Settings* and set `visualization:regionmap:showWarnings` to `false`.
