How to apply a filter to one specific metric in a chart?

[Loredata]

Hi everyone! I created a table chart comparing different audiences across a few metrics, as shown in the example below. To get 'Registrations' data, I use the 'Event count' metric with a filter on Event name = 'registration.' However, this filter impacts other metrics in the table, which I want to avoid

I tried creating the following calculation using a parameter, to use as the table chart metric. So, a dynamic metric selector.

And I created a Boolean expression for using it as a filter on the table chart, but my workarounds aren't working. Can anyone provide guidance? Thanks! 🙂

Create a custom measure to count the no of registrations. Pass Event name = 'registration.'  as the filter condition within this measure. It will only affect this field in your look.
