The recent thread on high-end oscilloscopes has reminded me of a project
that I shelved some years ago and might be due for resurrection:  I am
looking for a real-time display about 3" x 4" that can behave as an X-Y
oscilloscope with a bandwidth of about 100 Kc/s; a flat panel would be
ideal.
 
Currently I am using an actual X-Y oscillocsope to monitor the output
from a stereo gramophone cartridge, which allows me to check historic
discs for damage or faulty recording geometry.  The tube is about 14"
long, which means it has to be a standalone shelf unit and I can't build
anything like it into portable equipment.
 
I've not come across anything like this, but I'm sure such things either
exist or can be made by adapting something that is readily available.  I
have never been down the digital route, so anything that would need a
lot of programming from scratch will never get built.
 

 
How about this? https://tinyurl.com/39pkzb5v
I haven't used this Chinese kit myself but it's been around for quite
some time. The display is only 2.4" though. With an aspect ratio of 4:3,
that would be about 1.9x1.4.

That's the sort of thing, but it does need a 'Y' input and must start in
the correct mode on power-up, as the screen will be built into a piece
of equipment with no room for extra panel controls.
