Hello everyone,

I was looking through the source files on GitHub, trying to find the function that determines the automatic time interval though I could not find it.

I am working on a project, and I would like to have dynamic time intervals (e.g. large range =\> lower resolution, small range =\> higher resolution).

Does anyone know where I would be able to locate this function?

Thanks,

Tanner

Ultimately, auto interval calculation happens here: [https://github.com/elastic/kibana/blob/master/src/ui/public/time\_buckets/calc\_auto\_interval.js](https://github.com/elastic/kibana/blob/master/src/ui/public/time_buckets/calc_auto_interval.js)

That module is used by the `TimeBuckets` class: [https://github.com/elastic/kibana/blob/master/src/ui/public/time\_buckets/time\_buckets.js](https://github.com/elastic/kibana/blob/master/src/ui/public/time_buckets/time_buckets.js)

And the `TimeBuckets` class is instanciated for each date\_histogram bucket aggregation here: [https://github.com/elastic/kibana/blob/master/src/ui/public/agg\_types/buckets/date\_histogram.js#L56](https://github.com/elastic/kibana/blob/master/src/ui/public/agg_types/buckets/date_histogram.js#L56)

Hope that helps a little

This is exactly what I was looking for.

Thanks!
