If I have documents where value.keyword = A1, value.keyword = A2 ... A3, B1, B2, B3  
How would I get all of the A values to group together and B values to group together instead of having 6 separate bars on my graph?

This is using Visualization - Aggregation, not lens  
Thanks

Hi Miriam. The best way to do this is by adding a new "group" field and populate this field at ingest. So your documents might look like `{ "value": "A1", "group": "A" }`. Then you could perform the aggregation on the `group` field. But you'll need to update your existing documents using [`reindex` with a `pipeline`](https://www.elastic.co/guide/en/elasticsearch/reference/8.6/docs-reindex.html#reindex-with-an-ingest-pipeline) to populate the `group` field.

A second-best way to do this, but maybe less performant, is to create a `group` [runtime field](https://www.elastic.co/guide/en/elasticsearch/reference/current/runtime.html). This involves a little scripting, but you don't need to update your existing documents.
