> Is it possible to calculate value directly from a dashboard? The short answer is "no" -- you can't do this directly from a dashboard. _However_, you can achieve this using a TSVB visualization (which can then be embedded in a dashboard). What you're looking to do is called a [bucket script aggregation](https://www.elastic.co/guide/en/elasticsearch/reference/6.8/search-aggregations-pipeline-bucket-script-aggregation.html), which is [not yet supported in our standard agg-based visualizations](https://github.com/elastic/kibana/issues/4707), but [can be done using TSVB as shown here](https://github.com/elastic/kibana/issues/4707#issuecomment-325997105). Another more detailed example can be found in this thread: > [@Weighted Average in a DataTable of Kibana](https://discuss.elastic.co/t/weighted-average-in-a-datatable-of-kibana/185909/2): > > Hi Henrique, I think solving your problem will be a two-step process. You'll need to create a per-document field for cost \* volume, e.g. a field called volumeCost. You could create this field two ways, either by [reindexing your data](https://www.elastic.co/guide/en/elasticsearch/reference/6.0/docs-reindex.html#docs-reindex) and adding the field with a Painless script, or by creating a [scripted field](https://www.elastic.co/guide/en/kibana/current/scripted-fields.html) that calculates this value on the fly. The first option is a little more performant when querying your data but the second option might be easier. I think you can create a Timeseries v… --- _[View the full topic](https://discuss.elastic.co/t/take-calculate-value-from-dashboard/259093)._
