# Request a Data Analysis

Beyond [Topics requests](/crystal-advisor/talk-to-your-data/conversation/request-topics.md), Crystal lets you **activate** **capabilities** present in the Advisor by simply asking for them.

Right now, you can activate features linked to Crystal's [**data analysis**](/crystal-advisor/analyze-your-data.md) capabilities.

{% hint style="warning" %} <mark style="color:orange;">**Remember**</mark>

These capabilities are *only available for* [*Configured Topics*](/crystal-console/topics-configuration.md)*;* [*Auto-generated ones*](/crystal-advisor/talk-to-your-data/conversation/request-topics/entity-based-conversation.md) do not support them.
{% endhint %}

## Ask for an Anomaly Detection&#x20;

With the **Anomaly Detection** capability, you can monitor a Topic until the system finds an anomaly.&#x20;

To activate this feature, simply ask:&#x20;

1. *"Notify me / advise me / let me know etc"* + *"about"*
2. Specify the Topic of interest
3. Specify Filters (optional)

Crystal will give you a feedback about the result of your request (e.g. request succeeded, failed, etc.) and you will receive a notification when the analysis is available.

{% hint style="success" %} <mark style="color:green;">**Examples**</mark>

* *"Notify me about sales by week over time"*
* *"Advise me about sales by week over time for Italy"*
  {% endhint %}

{% hint style="info" %} <mark style="color:blue;">**Please Note**</mark>

You can activate the same capability *from the Topic Card* of the chosen Topic.
{% endhint %}

## Ask for a Threshold Monitoring

With the **Threshold Monitoring** capability, you can monitor a Topic until the value of the Entity goes above or below a specific threshold.

To activate this feature, simply ask:

1. *"Notify me / advise me / let me know etc"* + *"when"*
2. Specify the Topic of interest
3. Specify Filters (optional)
4. Specify the direction of comparison: *"goes above"* or *"goes below"*
5. Choose the threshold value: it can be an *absolute value* or a *percentage*

<details>

<summary>Recommendations</summary>

Consider the following recommendations to write the *absolute threshold value* correctly:

* The numeric value needs to be specified in full: you cannot include *“,”* or *“.”*&#x20;
  * These symbols should only be used to indicate a decimal number
* You cannot abbreviate the number
* You cannot include a currency symbol

For example, you can not specify a number like "$ 3,4K": instead,  you should write "3400".

</details>

Crystal will give you a feedback about the result of your request (e.g. request succeeded, failed, etc.) and you will receive a notification when the analysis is available.

{% hint style="success" %} <mark style="color:green;">**Examples**</mark>

* *"Notify me when sales overtime by week goes above 80 million."*
* *"Notify me when sales overtime by week goes above 80 million in Spain."*
* *“Let me know when my total sales growth rate goes under 10%.”*
  {% endhint %}

{% hint style="info" %} <mark style="color:blue;">**Please Note**</mark>

You can only perform this kind of analysis for the following Objectives:&#x20;

* Overtime Single Line
* Highlight
