I am currently using a date histogram for my visualization. Unfortunately, the date format seems to default to "yyyy-MM-dd". I would like to Modify it to "MMM-yyyy". I've applied that change on the field but I think while using date histogram it doesn't pick up that change. How can I accomplish this?

I tried Change Kigana \> Advanced Settings \> General \> Date format, but not worked in date histogram visualization.. And I couldn't find any settings in visualiations, sorry.

I would use a runtime field for this - we need to implement [https://github.com/elastic/kibana/issues/67206](https://github.com/elastic/kibana/issues/67206) before we have the native support.

as an example [runtime field](https://www.elastic.co/guide/en/kibana/7.17/managing-index-patterns.html#create-runtime-fields) you could do something like below but rather than `e` as your format you could select one from [this list](https://docs.oracle.com/javase/8/docs/api/java/time/format/DateTimeFormatter.html)

```auto
ZonedDateTime input = doc['timestamp'].value;
String output = input.format(DateTimeFormatter.ofPattern('e')) ;

emit(output);

```
