How to align y axes ( numeric from same chart) with different scales at zero ?

Here is more information regarding the context for the query and what I have tried so far -
I want to show cash activity over time. I’m showing 2 series on the chart - deposits vs withdrawals (stacked bar) and net activity (line). Major issue here is that I’m not always able to align the y axes for 2 series at zero. Using same scale would solve the issue but I can’t do that since net activity ranges in (+/-) millions while deposits vs withdrawals range in (+/-) billions. I don’t want to hard code scales either because I want scales to re-adjust when I filter/slice the chart using another dimension.
