### FAQ about Dimension Breakdown

<details>

<summary>Why is the pie chart visible only sometimes?</summary>

Whether the pie chart is going to be visible or not depends on which Measure you have selected.&#x20;

* When you select a measure like revenue, conversions or costs, pie chart is going to appear. It is because this measure can be **summed to a total.**&#x20;
  * Example: If you have **channel A** with **800 conversions** and **channel B** with **200 conversions**, we can make a sum and say that channel A did 80% of all conversions.
* When you select a relative measure like ROAS, the pie chart will be hidden. It is because when you add up the numbers for each channel, they **do not create the total**.
  * Example: If you have **channel A** with **ROAS = 800%** and **channel B** with **ROAS 200%**, the total ROAS cannot be calculated because, from this, we do not how big any of the channels is. This situation cannot be in any way captured by the pie chart.

<summary>How do filters work on this page?</summary>

Filters work the same as on any other page. If you select a specific dimension value, only data belonging to that dimension value will be presented on the page.

* It can be useful when you are trying to find information about a specific channel (like **Google Ads**) in a specific country (like the **US**) but you are interested in more granular information by Campaign or Ad Group.
  * In this case, filter by Site only **US** and by Platform only **Google Ads** and set the dimension in the page to the desired granularity.

<summary>Can I freely set up measures in the table?</summary>

At the moment, only two measures are supported. It is always the main measure for the entire page + one more measure of your choice. If you need to work with more measures at the same time, we can recommend either [**Performance Analysis**](https://docs.roivenue.com/roivenue-resources/roivenue-training/roivenue-features/performance-analysis) or using the [**export** ](https://docs.roivenue.com/roivenue-resources/roivenue-training/data-exports)feature for analysis of the data in a BI tool of your choice.
