Notable Features

Refactored Cartesian Charts

A new visualization engine provides for bubble charts, greater flexibility when mixing series types, and smarter defaults for cartesian charts. It also lays the foundation for future developments. The visualization framework is generally available now, but could previously be enabled using the “Enhanced Visualizations” Labs feature.

New LookML Parameters


Control data access at the field, explore, join, and view level based on user attributes with the new access_grant parameter.



Using two timestamp fields, quickly and flexibly calculate duration with the new duration dimension group. Like the time dimension group, this parameter accepts the intervals field that allows Looker developers to specify the units that matter to their model.


Improved Color Picker

Allow your users to have complete information right off the bat when choosing color palettes for their visualizations. Default color palettes as dictated by the Admin panel are suggested first, followed by Looker’s out of the box color palettes.

Regarding the access_grantparameter, is using/editing this restricted to admins? If not, couldn’t a user with LookML access just edit the parameter settings in their branch thereby getting access to something they shouldn’t be able to query?

Hey Jonathan, thanks for the question. You’re absolutely correct. I’ll clarify by mentioning that access_grant is not designed to be a system “permission” like the permissions you set in the admin panel; rather, it is designed as a developer tool and a feature of the LookML language.

If you’re looking to set up hard permissions to restrict access to data, database-side permissions combined with user attribute parameterized connections will be your best bet.

Just out of curiosity, are these release notes being released via the RSS feed any more or no? The specific one I’d been using was:


Userlevel 5

Oh neat, I didn’t realize you could set up RSS feeds based on tags. This was just an omission, I added just added the “release” tag.

We’d been using that tag to flag release notes and then figured a “Release Notes” category might be more useful. Good to know the tag is still worthwhile.

Cool!! TYVM!!

Userlevel 2

This looks good! Do we know if there is yet the opportunity to combine both a stacked column visualisation and a line?

Userlevel 5

This release will allow you to combine stacked columns with lines, however the resultant “mixed series” visualization can’t have split axes. You’ll want to make sure the combined values are of reasonably similar scale (either naturally or with Calculation).

Userlevel 2

Were custom visualizations always free, or were they at one time a paid feature? Either way, very excited to start using them!

Custom visualizations have been free from the get-go! I believe there are some firms that developed their own proprietary visualizations and offer them for sale, but the use of the custom viz feature and the looker-provided examples have always been free 🙂
