FREE Power BI Gantt Chart Visual for Dependency Lines & Data Prep Guide

The Microsoft Power BI Gantt visual is powerful - but poorly documented. Most issues with milestones, parent tasks, and sorting aren't visual configuration problems; they're data preparation problems. This free resource gives you what the official documentation doesn't: how to structure your data model for milestones, parent tasks, and correct task sorting, plus a basic dependency lines/links feature not included in the original visual.

Who will it benefit:

PMOs and Power BI Developers building Gantt charts for project tracking who are struggling with data structure or missing dependency line functionality.

This resource is built on Microsoft's open-source Power BI Gantt visual, available on GitHub. The dependency lines feature included is basic and configured for monthly timeline view only - it may not work correctly with other timeline types such as weekly or quarterly. It demonstrates the concept and can be extended to suit your requirements.

Data preparation is the key to unlocking the full capability of the native visual and this customised visual. The guide included in the zip file focuses on getting your data model right before touching any visual settings.

Based on Microsoft's open-source Gantt visual (MIT licence). Provided as-is. No direct support is offered - refer to the GitHub repository (https://github.com/microsoft/powerbi-visuals-gantt) for visual-related issues.
