LineChartView: Using two different colors in one dataset

[mako9]

Hey there,
I'm trying to produce a LineChartView like in the image. It's a continuous moving line chart which changes the color when reaching a specified y-value.
How can I achieve something like this?
I already tried using two datasets combined but it doesn't work well.

Thank you,
Mario

Hi Marrio, I think you can try override drawLinearFill method for implement different color fill.

yes, but it seems requires lots of overriding. but you can get some idea from drawLinearFill though
