Barpolar labels issues

Screenshot 2021-09-14 at 09.19.48
I have problem with labels in such a busy barpolar chart as you can see.

Is there an option to maybe show labels on the lines , so they don’t overwrite each other?

Or at least to show labels on hover, even if value is 0, so I can remove these axis labels ?

Help appreciated.

Anyone can lend a hand here?
