bug #55064 looks related.
Anyway even 35 MB RAM for a graphics handle about just a few data is just ridiculous.

On Windows it's not so bad, with a 64bit idx 5.0.0 dev cross-build "just" 35 MB per figure :-)

I can confirm that memory consumption has been going up. I tested on a Linux system using self-compiled binaries.

Results for a new figure

Octave 4.2.1 : 24MB
Octave 4.4.1 : 48MB
Octave 5.0.0 : 48MB

The amount might be larger on Windows, but the trend is the problem.

Hello all!

Each invocation of the "figure" command in version 4.4.0 requires extra 110 MG of memory while in 4.2.1 it requires about 3-4 MG.

Thanks.
