Ability to change transparency of color under stacked area chart line

[luke8]

At the moment, the area under a line in a stacked area chart uses the color of the line but presents it with a level of transparency. This means that the fill color doesn't match to the color presented in the key. Ideally, it would be good to be able to customize the level of transparency of the fill color.

I've got to say that the fact this has still not been resolved as it needs more votes is mental... Removing the stroke width makes the chart look ridiculous, it's not a workable solution.

Two years and something this basic still has not been fixed. Come on MS pull your fingers out!

We are in 2022 and this feature has not yet shipped... Makes it impossible to use stacked area charts in presentations and use alternate solutions.

2023 and we still don't see it.
