Hi ,
During the development of my kibana plugin : [https://github.com/GregBoero/kbn\_vis\_multiple\_graph](https://github.com/GregBoero/kbn_vis_multiple_graph)
something hit me about metric.
is it possible to customize a metrics, by example, is it possible to create a conditional count / sum / unique count... ?
I saw that the metrics are stored in kibana\src\ui\public\agg\_types\metrics but i don't understand it , there is a documentation or anything on the subject
Thanks and Regards

hi @GregoryB-T,
the short answer is no.
Kibana doesn't have anything right now that allows an end-user to create a conditional expression, and doesn't have any documented public developer APIs to introduce this functionality through a plugin.
The folder you are pointing to contains the implementation of all metrics. Each of these maps to a metric in Elasticsearch [https://www.elastic.co/guide/en/elasticsearch/reference/current/search-aggregations-metrics.html](https://www.elastic.co/guide/en/elasticsearch/reference/current/search-aggregations-metrics.html).
For conditional metrics, I think you would need something like a bucket script ([https://www.elastic.co/guide/en/elasticsearch/reference/current/search-aggregations-pipeline-bucket-script-aggregation.html](https://www.elastic.co/guide/en/elasticsearch/reference/current/search-aggregations-pipeline-bucket-script-aggregation.html)). It allows you to compute a per-bucket value, with custom scripts in painless. There is no support for this yet in Kibana, although it's been requested [https://github.com/elastic/kibana/issues/4707](https://github.com/elastic/kibana/issues/4707).

Hi @thomasneirynck,
thanks for your answer and the links,
the Bucket Script Aggregation in Kibana will be a major step-father in kibana data manipulation, but I don't think it's fit to my use case,
let take an example :
In this visualization my bucket (X-Axis) is not conditional, but I may want that my second Y-Axis is a unique count of the field named project where the field named action contain the string Creation
Maybe I will dig into the Control visualization to see how you have customized the Metric part of the visualization and handle the index-pattern link it may help me to find a way of doing that
Thanks and Regards
