LineChard with different color for filling

[YevhenHerasymenko]

I want to create line chart and have two color for filling under the line (I want to have new color after same level). For example red color after same level which notify that something bad has happened.

From an Android question I think you have to create a dataset for each color you want to use.

@wolf81 is right, creating two line with same data, and you can fill two different colors. But why not just calculate thew new color from the two parent colors?
