no. from later explanations, what he want to hear is justifiable excuse why analog is still applicable today. he doesnt care if digital is better, he only want to know why analog is better! so maybe he can scour some tek analog scope with sampling head that are still in ebay while they are still there... btw x-y art is just for kids who have nothing better to do imho, no offense... https://hackaday.com/tag/oscilloscope-art/

I said truth, only thing CRT scope does better is X-Y, but difference is only visible with scope art. I have no use for scope art, but i don't judge.
If someone likes it, good for them.

X-Y is also good for curve tracing of non-linear devices.
Occasionally, one might need a Lissajous figure display for other than Christmas decoration.

I think I saw one of those... Oh wait, they put a $20 LCR ESR Transistor checker in the same box  ;D

All of my scopes will do that just fine... It's really fast dynamic updates (like analog video on CRT scope) that you cannot do or only partially....
