# Drill-down or Reference Charts

***

Reference Charts in **Infinity** allow you to implement **Drilldown** functionality seamlessly. They create an interactive link between a **Source Vector** and a **Target Vector** or **Storyboard**, enabling deeper exploration of your data.

* **Source**: The originating Vector.
* **Target**: The destination Vector or Storyboard.

You can connect multiple Targets to a single Source by mapping Variables correctly. Ensure that all required Variables expected by the Target are provided by the Source.

### How to Create Reference Charts

1. **Open the Advanced Editor**\
   Navigate to the Advanced Editor where you manage Vector configurations.
2.

```

3. **Go to the References Tab**\
   Click on the **References** tab and select **Add New**.

```

5. **Configure the Reference**
   * **Type**:
     * **Insight**: Choose this if the Target is a Vector.
     * **Storyboard**: Choose this if the Target is a Storyboard.
   * **Name**:\
     Select the Target Vector or Storyboard from the dropdown list.
   * **Variables List**:\
     This list displays the variables expected by the Target. For example, "Quarter" might be a variable for the Target Vector **Sales Details by Quarter**.
   * **Variable Mapping**:\
     For each Target variable, choose one of the following from the Source:
     * **Dimensions and Metrics** available in the Source Vector
     * **Existing Variables** used in the Source Vector
     * **Pivot Columns** (Header) if applicable
     * **Custom Value** (Static value manually entered)

7\. **Choose Location for Opening Target**

* **New Tab**: Opens the Target in a new browser tab.
* **Same Tab**: Opens the Target in the same browser tab.
* **Frame**: Opens the Target in a popup window.

By using Reference Charts, you empower users to navigate across related insights intuitively, creating a connected and dynamic analytic experience.

Would you also like me to create a quick diagram showing how the Source and Target vectors are linked through variables? It could make the concept even clearer! 🚀
