Forced same Y axes in "line and stacked column chart" (dynamic, but same) new 3. option

Its either auto, of fixed - we need a 3. option, "auto but shared".

Scenarrio Im looking at revenue vs budget - and i want the linechart and the stacked column to follow the same Y axes - I could just make them fixed to say 100M but then when i click on a small sub division it stop to make sence.

if they are on auto, then 1 day they are the same, another day they are different, this is confusing for the end user.

it should be dynamic (Auto) but linked so they are always the same.
