Coloring scheme implementation

[alexcot13]

Would it be possible to create a new version which would make it possible to apply a coloring on the graph thanks to the values ​​reached per segment and not a coloring on the whole path?
For example, let's take a 3-step visualization: 0 years / 5 years / 10 years. I have two possibilities: dead or alive.
I would like to be able to color my segments from 0 to 5 and from 5 to 10 according to the arrival value on the segment. Today I can only apply one color for the entire 0-10 years journey. At 0 years old: everyone is alive, at 5 years old, I have 50/50, so I have two segments that go from 0 to 5, one blue (alive) and one black (dead). Between 5 and 10, I end up with 75% dead, so I must have 75% black starting from the 5-year bar and 25% blue (alive).
Many thanks for your feedbacks,
