Line charts anti-aliasing

Are line plots made with Go.scatter by default anti-aliased? Thanks for letting me know!

I’m not seeing very smooth anti-aliasing, when using a screen resolution of 1920x1080 on my hardware (not with width=1 nor width=5 as the line thickness). In fact, the micro-jagged look of the lines looks as if no anti-aliasing is employed at all. I do get anti-aliasing with other OpenGL applications on the same hardware.
