# Setting Up Drill-through

### How to Set Up Drill through in xViz Gantt Chart?

**Drill through** allows users to explore detailed information related to specific data points in your report. Follow these steps to set up drill through for the xViz Gantt Chart:

1. **Create a Target Report Page:**

* Begin by creating a new report page. This will serve as the target page for drill-through.
* Design this page with the visual elements you want to display when users drill down into specific data.

2. **Configure Drill through on the Target Page:**

* Open the target report page.
* In the Visualizations pane, locate the Build visual section.
* Drag and drop the field that you want to enable drill through for into the drill through well. This field will act as the trigger for drill-through actions.

3. **Automatic Back Button Creation:**

* When you add a field to the drill through filters well, Power BI automatically generates a back button visual.
* This back button becomes a clickable element in published reports.
* Users who view your report in the Power BI service can use this button to return to the original source report page.

4. **User Interaction:**

* On the source page of your report (where the xViz Gantt Chart is displayed), users can **double-click** a specific data point.
* This action opens a context menu that supports drill through.
* Users can choose to drill through to the target page associated with that data point.

5. **Filtered Target Page:**

* When report readers select drill through, the target page is dynamically filtered.
* It displays relevant information related to the specific data point they double-clicked on.

Remember to test your drill-through setup thoroughly to ensure a seamless user experience. Happy reporting!
