Cannot hide bubbles shown from parallel cordinate plot analysis

I’m struggling to erase bubbles shown in parallel cordinate plot chart. I checked forum for simillar problems and I found the thread below was exactly same circumstances that I’m in.

Parallel Coordinate Plot Issue (Analytics) Wallacei - Grasshopper / Wallacei - McNeel Forum

However, as Reinhardt failed to solve, my problem cannot be solved with rhino updates.

Is the only way to solve this problem is to open in rhino7?
