This is fantastic. It's been a huge shortcoming of Power BI that you cannot make calculations from the intuition of the matrix visual. It's a huge pain, even for an experienced developer, let alone for a user/beginner, to first translate your intuition to the filter context before writing the code. This finally solves that issue!

It's one step closer to the flexibility that eg Business Objects offers, but in this case with more elegance and functionality. Power BI is slowly (finally) turning into a tool I can be proud to use.

This is probably a good way to provide end users with a way to change the operators used in a visual. Quite useful as well if you are performing calculations on top of already complex measures that only need to be recalculated on the context of an specific visual. Awesome video as usual! Thank you Alberto!

Q: What could be the reason that SSAS-onPremise isn't supported? Is VisualCalculation executed by FE or something on top of FE?
