Ingame curve/graph editor

Is there any way or some sort of library to implement simple curve/graph editor for ingame use?

It seems no, there Slate Curve editor widget, but module with it sit in editor directory and EULA prohibits redistribution of editor modules. You need to code it yourself in C++ (I thin simplest way would be used AHUD canvas, you could even do this in blueprints as drawing functions are exposed AHUD | Unreal Engine Documentation) or search for plugin in marketplace, or you might google something out

Thank you, this is a very good start for me
