Sigma Assistant in the workbook: plan and build modes (Beta)

Sigma Assistant can now help you design and build workbooks using natural language prompts.

You can use Assistant in plan and build modes to do the following:

• Build dashboards with charts, tables, KPIs, and filters to visualize and explore your data.
• Set up structured data entry with forms, input tables, and actions.
• Accelerate the development of AI-powered apps from idea to working product.

For more information, see Use Sigma Assistant to build dashboards and apps.

Sigma now supports the Azure Australia region

Sigma is now deployed in Azure Australia (australiaeast). This region, located in New South Wales, gives customers in Australia lower latency and enhanced performance when connecting to Sigma. A disaster recovery region is also available (australiasoutheast).

Workbook elements

Ad hoc calculated column support

Adding ad hoc calculated columns in pivot tables is now supported. This allow you to perform one-off calculations in a pivot table column, without modifying the underlying dataset or restructuring your pivot table.

For more information, see Create ad hoc calculations.

Create tables from an array with unnest (Beta)

You can create a table from an array of values using the Unnest feature. After selecting a data source and identifying a column with array data, Unnest creates a new table element with one row for each item in the array.

For more information, see Create a table from an array.

Responsive segmented controls

When the values for a segmented control are too long to fully display when viewing or editing a document, the control appears as a drop-down menu instead of truncating the text in the control.
