Hello, How to add a Field to Range Aggregation? Thank you ![Elastic_Forum_Image4a_How%20to%20add%20a%20Field%20to%20Range%20Aggregation](https://us1.discourse-cdn.com/elastic/original/3X/1/b/1bbb16255f959a6b07fac23b50a93fa893e4335e.jpeg) ---

In order to use a field there it has to mapped as number in elasticsearch. Can you share what the mappings look like for the field we want? ---

Jon, What specific Mapping information is needed? The “Blue” Field is a Number ![](https://us1.discourse-cdn.com/elastic/original/3X/9/5/95ce83b8709b471d6ef1a4a6fe6caaa1297a9b54.jpeg) Thanks, -Mark ---

Ah 🙂 Kibana thinks its a string for some reason. We can check the elasticsearch mappings directly with ```auto GET /_mapping ``` in dev tools. If it says keyword or text there we'll have to reindex the data with a numeric type. If it is a numeric type we can click the refresh icon on the index page in Kibana. ---

In dev tools, does "Type" need to be set to "Float", or perhaps some other Type? ![Elastic_Forum_Image4c_DevTools_map%20a%20Field%20for%20Aggregation](https://us1.discourse-cdn.com/elastic/original/3X/b/f/bfd94ff8a8fc5f15e51041079704688253410991.jpeg) ---

Yup, one of these: [https://www.elastic.co/guide/en/elasticsearch/reference/current/number.html](https://www.elastic.co/guide/en/elasticsearch/reference/current/number.html). If it has decimals, float or double, if not long or integer. ---
