If you’re interested in cascading parameters and Power BI custom connectors is an option for your project, you should give a try to Navigation Tables. Which soon enough could make their way into M standard library. If this is not an option, you might find your solution in the next few scrips tangled between functional programming concepts. You will also learn about:
Where to set the allowed values for function parameters
How to build a function inception with higher order functions
How to access a variable outside its scope
And finally get to a result which mimics cascading selectionsRead More »
While I enjoy that now I can write PowerQuery expressions everywhere in Analysis Services, the fact that I don’t know what is available at hand when I embed an M script in my model — is a bit of an annoyance. Especially when that script ends up working in Data Tools and Power BI but spits up various errors during processing of a table.Read More »
Recently I started exploring the limits of standard charts in Power BI and ended up drawing all sorts of mathematical functions. For the fun of it, I’ve decided to port a famous Homer Simpson-like curve to DAX and was really impressed by the result.
As always, there is no magic involved, just the usual trio:
