Draw many curves with different colors

Hi all,

Does anyone know how to add the curves of different colors (like screenshot) in UE4?

I want to add more than four curves of different colors.

After I look up the CurveColorCustomization.h/cpp and SCurveEditor.h/cpp,
I still have no idea about this part.

FCurveViewModel?? FLinearColor??

Thanks for help.

I am pretty sure you are searching for a Color Curve. You find them under Misc->Curves and then clicking on CurveLinearColor.
