A scripted field can use all data which is stored in a single document (no cross-document calculations). What exactly should your machine score do? ---

Scripted fields are a low-level technology which allows you to do calculations based on multiple fields within a document. It doesn't offer formulas like machine score out of the box. You will need to come up with a formula based on the fields you have, then I can help you transforming it into a scripted field. ---

thank you Very much for the answers. the follow values are used to show a machine score visualisation. ![image](https://us1.discourse-cdn.com/elastic/original/3X/9/f/9fbb250ea700ef7c54b49a3871fc8b7bc08305d5.png) ---

This looks like a splunk expression - I'm not too familiar with them, but it looks like machinescore is just a regular field in your data, so you wouldn't need to do anything special, just do an average of the `MachineScore` field. To do the over time comparison, make yourself familiar with the TSVB visualization: [TSVB | Kibana Guide [7.12] | Elastic](https://www.elastic.co/guide/en/kibana/7.12/tsvb.html) ---
