# Data labels

> Write values directly onto chart marks, with configurable position, format, and font size.

Data labels write values onto the chart itself, so a reader gets exact numbers without
cross-referencing an axis.

## Enabling data labels

Open the **Style** tab and turn on **Show data labels** in the **Data labels** section. Labels are
off by default.

The setting covers the whole chart rather than one measure: every measure drawn is labeled. A bar
labels its total at the end of the bar; a line or an area labels each point's value above the point.

## Label settings
