How to format Bubble chart or maybe feed from repeating group?

So, I’m using the basic Bubble chart plugin. I have an API feeding to a repeating group that is able to convert the numeric months to Month - Year in the repeating group. Is there a way to do this same condition in the Bubble chart at all OR is there a way to maybe just feed the chart from the repeating group instead of the API data? Then it would be formatted already? I’m guessing the answer is no but just burned too many hours now trying to figure it out for sure.

Any other suggestions greatly welcomed. : )
