# Phenotypic Data Exploration

Please note, the data present in this page is intended for training purposes only. Information about the data present in this documentation is listed [here](/cohortbrowser/apollo_introduction.md). 

The overview tab is dedicated to the phenotypic data that has been ingested in your dataset.  The phenotypic data is able to be displayed utilizing tiles, and these tiles will have different tables or figures based on their data type.  

## Adding Tiles

### **Simple Tiles**

1. Open Cohort Browser
2. Select "+ Add Tile" on the top right corner

4. Repeat until you select the amount of tiles that you are wanting (up to 15)

### **2D Plots**

* Used for more advanced comparisons
* Add comparisons by selecting the first filter, then selecting the "+" sign for a secondary field
* Then, edit the data field details

Here is the overview of the 2D plots that are available based on data types:

### Steps to Create 2D plots

1. Open Cohort Browser
2. Select Add tile on the top right corner

3. Find the characteristic you are wanting to start with and select it, such as biological sex. This is the same step as adding a regular tile, but you will NOT select Add tile.&#x20;

4. Instead, add a secondary field by selecting this next to the second characteristic you are wanting to view.

5. You will then have options to change the graph with those parameters.&#x20;

6. Then, select the add tile button on the bottom right below the new graph. This will add it to the cohort browser.

## **Limits on the Cohort Browser**

* Limited to 15 tiles overall in dashboard
* Limited to 30 columns in Data Preview
* Add 1-2 tiles at a time, wait for them to refresh before adding more tiles.
