> "(user at the end of time period - user at start of time period)/user at the start of period " using this formula. If you are wanting to perform calculations like this, it sounds like a use case for bucket script aggregations. You can't currently do this using Kibana's core bar/line charts, however there is a way to do this in TSVB. This recent discussion has some links which should explain in more detail: > [@Take/calculate value from dashboard](https://discuss.elastic.co/t/take-calculate-value-from-dashboard/259093/2): > > 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).
