A very common requirement when building Power BI reports is to allow the end user to change what is displayed on a chart axis dynamically. A lot of people have blogged about how to do this – Kasper’s blog post here is a great example – but the problem is that all of these solutions […]

In the comments to my last blog post on how the order that you select columns can affect the output of certain calculations, both Bradley Sawler and John B.

Maybe this is obvious to more experienced Power Query users, but something I always point out when I’m training people up on Power Query is that the order that you select columns in the Power Query Editor window (both in Power BI Desktop and Excel) can affect the output of certain transformations.

A long time ago someone – probably from the Power Query dev team – told me that adding primary keys to M tables could improve the performance of certain transformations in Power BI and Excel Power Query/Get&Transform.
