Format chart legend

Chart legends associate chart mark colors, shapes, sizes, types, and other attributes with specific groups or values. This helps users interpret data when the chart metric is distributed into categories (like regions or product types) or when a metric defines size or color scale. Most visualization types in Sigma support legends that you can format to improve chart usability and readability.

This document explains how to change a legend’s visibility and customize its position, font size, and text color.

The ability to format chart legends requires the following:

• You must be assigned an account type with the Explore workbook and/or Create, edit, and publish workbooks permission enabled.
• You must be the workbook owner or be granted Can explore or Can edit workbook permission.

2. Select Element format in the side navigation, then click the Legend header to expand the section.
