This means it is now possible to have the output of a DAX measure displayed as an image in a Power BI report and this in turn opens up a lot of new possibilities - including the ability to work around the maximum size of a text value that can be loaded into Power BI (see my previous blog post for more details) and therefore work with larger. So as dmstat calculates its output, null=0 behaves exactly like null=0. When multiple values are returned the function will return BLANK but what is great is that you now also easily add a default value yourself so can do something like this: PS as you can see there is a squiggly under year, there is currently a bug in the intellisence that causes this.
