[Feature Request] AreaSeries with different styles for above baseline and below baseline #74

What is the feature ?

Currently, AreaSeries colors the area from Path/LineSeries to baseline. This is done with Polygon. It would be nice to have two different colors for areas above and below.

Why do you need the feature ?

This makes some graphs much nicer to read.

What is the use case ?

Hi, that's good idea! I am going to make this happen before next release, please let me know if you think there's anything else can be improved. Thanks!

Hi I am also really interested in having this feature available! I would like to do a win rate graph with a baseline of 50% and have the area color correspond to the winning player but this is impossible right now for me.
