What's new in Sigma

Data modeling

Data models (Beta)

Build data models to create collections of table and input table elements that can be reused as data sources in other Sigma documents. Use the familiar workbook-style format to easily transform and analyze reusable elements, and view key insights into data model usage across your organization.

For more information, see Intro to data models and Create and manage data models.

Functions and calculations

Advanced calculation options for metrics

Quickly convert metrics to cumulative aggregates (grand total) or relative aggregates (percent of total) in tables, pivot tables, and visualizations.

Open the relevant column menu, then hover over Advanced calculations and select an option to show the grand total or percent of total. Available percentage breakdowns (by grand total, x-axis, row, column, etc.) depend on the element type.

Workbook elements

Interactive chart legends

Interact with chart legend entries to quickly focus on specific data subsets.

Charts containing legends that represent qualitative segments (like categories or series) support the following interactive filtering capabilities:

  • Hover over a legend entry to highlight corresponding data points.
  • Click a legend entry label to isolate corresponding data points.
  • Select or clear the checkbox of one or more legend entries to show or hide corresponding data points.
  • Click anywhere (within the element) outside of the plot area or legend to reset the chart display.


Changes resulting from chart legend interactions persist when you switch between workbook modes; however, they don’t persist across user sessions and aren’t saved when the workbook is published.

Bug fix

  • To preserve data integrity, Sigma no longer converts Yes/No and 0/1 values to True/False boolean values in CSV uploads.
