Field parameters in Radar Chart 2.0.2

Hello Power BI Community,

I'm working on a project using Radar Chart 2.0.2 and need assistance with field parameters. I want to dynamically select fields within the chart based on user input, specifically using the requirement values A-D as criteria. Additionally, I would like the field parameter to have the capability to select a specific country. 

How can I effectively utilize field parameter in the Radar Chart? Any guidance would be greatly appreciated.

Here's some example data:

I've tried this already using field parameters but no values appear on the radar chart when using the field parameter as the y axis and Requirement as the category.

Thank you
