Field Parameters in Deneb Visuals
No, field parameters aren't currently supported. They don't work well in a "flexible dataset"-type situation and have to be very explicitly defined in a custom visual (which is why they work well in visuals with defined data roles).
I will be planning some limited support for field parameters in v2, and the RFC is here if you wish to add your thoughts to it or track its status. As field parameters are in still preview for Power BI, it will give sufficient time for me to review the GA implementation and bear any additional changes in mind before I start working on it, as it's quite a big piece of work.
Deneb version 2 is currently being scoped and planned, and I don't have a solid ETA yet. We may start seeing alpha builds very late this year or early next year if all goes well. I develop Deneb in my free time and free of charge, so it's hard to gauge exactly how long things can take.
I forgot to include the magic measure with more than 2 a switch statement would be better but for a simple test it works. Same logic could be used for the other axis.
Ah, this is similar to doing it with expressions inside the specification, so will work fine, as long as you don't mind setting up a measure to do so 👍
We'll do something like this automatically to the dataset internally when feature support is added. As per my other reply, we don't currently have anything useful in the visual metadata that tells us you're using a field parameter (or what its name is), so we'll likely create special roles (buckets) for you to add them to which will handle the conversion, unless MS can add some more metadata (which I have asked for, but have no idea if we'll get it).
Cheers,
