Dashboards & Visualizations

• 
  Reorderable Filters. The order in which filters are displayed can now be configured in the Add/Edit Filters modal found in the gear menu on Dashboards.


• 
  Tiny Charts. Dashboard elements are simplified as they are reduced to allow for smaller-than-ever dashboard tiles that still contain useful information. Learn More.
  


• 
  Column Limit Warnings in Dashboard Tiles. Since visualizations constrained by reaching the column limit can produce inaccurate charts, Looker now surfaces a warning inside the visualization panel and on dashboard tiles for improved data interpretation.


• Charts with pivots or multiple measures with the same value_format now apply that format to the axis tick marks.

Powered By Looker
