VideoTek (Avisynth and MPV Waveform Monitor)

I love the Tektronix Videoscope I have at work, but I can't use it at home, that's why I tried to reproduce a similar output using Avisynth built-in videoscope (Histogram).
Please welcome VideoTek, a Tektronix-like waveform monitor for Avisynth and MPV.

VideoTek() (Avisynth Version) - VideoTek (MPV Version)

picture (top left), luma (top right)
chroma (bottom left), audio channels and Lissajou (bottom right)

Avisynth Usage:

just call the function: VideoTek() in your script

MPV Usage:

Press "Y" to turn on the waveform monitor while you're playing back a video.

Please note that due to the limitation of LAV Filter Complex, the MPV version is slightly different from the Avisynth Version:
