Power BI Desktop - March 2021 Update
Part one of a three-part series of blogs

There are two tiny changes in the March 2021 update - X-axis constant lines and a couple of tweaks to DAX - but still the big logjam of changes remains in preview.

  2. A new X-axis constant line
  3. Slight tweaks to DAX

We've been creating our idiosyncratic monthly blogs on Power BI updates since November 2016, and also deliver online and classroom Power BI courses.

Power BI Desktop - March 2021 Update

Frustratingly, everything exciting which was in preview last month (and the month before for that matter) is still ... in preview:

Preview features

Soon you'll be able to use the Azure map visual, view all field lists in a consistent way and create grids of charts comparing different values from the same dimension ("small multiples"). Soon ...

  

In addition to the above features, the new Power BI model view is still also in preview (you're still prompted to turn it on whenever you view the relationships in your model).

This leaves us with the following meagre list of changes for this month:

New feature Notes
X axis constant lines You can now add vertical lines to time series charts using the Analytics tab.
Tiny DAX changes There's a new IF.EAGER function, as well as a slight tweak to how the CALCULATE function works.

Probably the most exciting update, however, isn't in Power BI Desktop, but can only be found in Power BI Service: the ability to create flow diagrams for Power Query Online, which is surely a harbinger for the way Power Query itself is going.
