filtering legends of the line chart or any other visual

[Anonymous]

hi all,
Need help for the following 2 requirements - 

1. I have a line chart with multiple legends. The legends (forecast, production plan etc) are taken from different tables. And the x axis is calendar axis having joins with different tables used as legends
Screenshot below

I need to dynamically select the legends. And accordingly the chart should change.
Expected result - 

2. I have a measure that calculates Projected Inventory (PI) =  Production plan - Forecast. 
It should calculate PI based on what I select at the filter.
If I select only Forecast, then PI formula should return ----->Forecast.

If I select Forecast and Production plan, then it should return --->Production plan - Forecast.
Can I have the logic for the same.

let me know if you want any more inputs.

thanks for helping
