# Gantt Chart

> Set up a Gantt chart for task timelines.

A Gantt chart shows **tasks** over time with start and end dates. Useful for project timelines and scheduling.

## Data Requirements

* **Task** dimension (task name or label)
* **Start date** column
* **End date** column
* Optional: **Duration** or additional dimensions
* Gantt is enabled when you have **4+ dimension columns** (per `getEnabledChart`)

## How to Set Up

1. Create a metric with a task dimension and start/end date columns.
2. Click the **Charts** icon and choose **Gantt** (if available).
3. In chart configuration, assign:
   * Task/label dimension
   * Start date column
   * End date column
4. Use **Appearance** for colors, labels, and tooltip content.

## When Gantt Is Disabled

Gantt may not appear if you have fewer than 4 dimension (non-numeric) columns. Add more dimensions to your metric to enable it.
