#### **a. For Reference lines**&#x20;

The xViz Gantt provides users the option to set multiple reference lines based on different logic:

2. **Date configuration**

We need to configure one single date to add the Reference Line on the Chart:

* **First-of-date –** Displays Reference Line on the earliest start date from the data where the Timeline starts.
