I've run into problems like this before. You can only use dual axis, you can't show three separate viz like that... as far as I know. If someone has a calculated approach, I'd love to know. I just downloaded the TabPy API, perhaps that might help leverage a solution
Thanks @Zach for looking into this issue..Pls let me know if you can find a solution using Tableau python server.
Meanwhile,Anyone had different approach to solve this???
