how tomake leftAxis.inverted and LineChartDataSet.fillColor not inverted

[iOSCoderJane]

this picture is normal:

and this picture is make chartView.leftAxis.inverted = true

we can see that left.inverted make the fillColor also inverted, I want the fillColor not inverted. how to make that style?

This is the correct implementation so far. Filling always start from the lower y axis (bottom side). If you want the opposite filling, you have to override the filling method yourself.

ok, I want to know how to override the filling method by myself. which class or which prootocal. thank you

it's not that easy. You have to understand how the line chart renderer works. But basically, start from drawLinear() which contains the filling func.
