LineDataSet: shader with multiple color

[NihalDesai22]

Hi @PhilJay !

i am looking for this graph which indicate the percentage of battery charge over the time. whenever the battery is charge it should show that green portion in the graph and when it drain it reflect with the time along red portion.

i tried multiple things to add this shaders things to show below my points.

So, I am wondering if there is any possibility to improve this library in a way that we can use different shaders for each dataset? or achieve similarly in the image.

Thank you for being so helpful.
Best regards
