# About analytics

Learn how the basic period, comparison period, and graph work so you can analyze your Library analytics more accurately.

## Basic period

<figure><img src="https://1857767629-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2Fo7CC5HKFh1guYnGcyftj%2Fuploads%2FeRxUDSJhkDClg0QavyAv%2Fintro-1-en.png?alt=media" alt=""><figcaption></figcaption></figure>

* The basic period is the date range that analytics are calculated for.
* By default, it runs from the 1st of the current month to today.
  * <mark style="color:purple;">If you check player load analytics on March 15, the basic period is set to March 1–March 15.</mark>
* Click the **\[Basic Period]** drop-down to change the date range.

## Add a comparison period

* Click **\[Compare to]** next to the basic period to add a comparison period.
* When you add a comparison period, two graphs appear: one for the basic period and one for the comparison period.
* Each period has its own color.
* Hover over a point on the graph to see daily figures for both graphs.

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

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

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://support.charlla.io/en/userguide/statistics/intro.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

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.
