Need Help with Dynamic Axis Title and Tooltip in Deneb (Power BI)

the Secondary Y-axis values change dynamically based on the parameter selection.

How did you get that to work? Usually the Deneb visual uses the materialized version of the parameter.

You will also need to force that parameter to a single select slicer unless you want to deal with the list management.

Can you show me how to modify this PoC to have a dynamic parameter?

EDIT:  Forgot about the "extra measure" trick. Provide Field Parameter Support · Issue #238 · deneb-viz/deneb

So - create two measures - one that gets the parameter value and one that gets the parameter title. Then use the second one for your dynamic axis.

Here's a bit of a gimmicky version abusing the legend instead.
