# Custom calculations

Drill Down Tree allows adding a new calculation as a measure in the diagram. This means it is possible to create aggregated calculations like profit ratio, enabling users to gain deeper insights into their data. By including such custom measures, users can analyze performance metrics more accurately, identify trends, and make informed decisions based on comprehensive data analysis.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.infotopics.com/drilldowntree/configuration/customize-measures/custom-calculations.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
