Anyone who can edit the dashboard · Updated 8 Nov 2026

A Comparison page puts a column's values side by side, for example two regions, products or teams, with the leader marked. Readers can change what is compared while viewing. Anyone who can edit the dashboard can set one up in the dashboard editor.

  1. Add one with Add → Page → Comparison, or switch an existing page's structure to Comparison.
  2. Open Design → Format → Comparison settings…, or click the compare bar on the canvas. The Comparison panel opens.
  3. Choose the settings below.
