# Data labels

> Display totals directly on stacked bar charts with configurable positioning and formatting.

Data labels show the aggregate total value above each full stack on stacked bar charts. They let users read exact values without cross-referencing the Y axis.

## Enabling data labels

Open the **Fields** tab and enable the **Data Labels** toggle.
