Hi, Does kibana support weighted average if yes, can someone shed some light on it ? or is there any way to write a query for same? Thank you.. ---

What are you weighting the values by? Something in each document or some fixed values? Off-hand, this seems like a candidate for using Scripted Fields in Kibana. This blog has some good examples; [https://www.elastic.co/blog/using-painless-kibana-scripted-fields](https://www.elastic.co/blog/using-painless-kibana-scripted-fields) Regards, Lee ---

Hi Lee, thanks for your response can i do below calculations ? ![image](https://us1.discourse-cdn.com/elastic/original/3X/d/c/dc1da4cab78313981764ac212ddd288883bcfbf0.png)Data ![image](https://us1.discourse-cdn.com/elastic/original/3X/8/c/8c0419c09c51ae1826470d6a0433294858fad562.png) if a person smoke more than three times habit\_risk\_score should double **final\_risk** per subject = habit\_risk\_score \* weight can you guide me on how to store new field "final\_risk" in existing index and visualize it in Kibana thank you.... 🙂 ---

Here's a good blog about scripted field in Kibana; [https://www.elastic.co/blog/using-painless-kibana-scripted-fields](https://www.elastic.co/blog/using-painless-kibana-scripted-fields) But note that scripted fields are calculated per document. So you wouldn't be able to use the total count of multiple docs for a subject to influence the weight. Maybe you can calculate a risk score for each doc and then add them up? ---

Thanks Lee , i am trying this, can we use scripted field as input for other scripted field. example : First use regex to create a scripted field **habits**'smoke' Then create another scripted field **score**'2' value based on previous scripted field through if construct ? ---

I don't think you can use one scripted field inside another scripted field. ---
