[Feature Request[ XY Plot additional option for ksampler_output_image parameter

[akawana]

Please add an option to XY Plot for the ksampler_output_image parameter — something like “Plot only if multiple” (name doesn't matter).

The idea:

If we are generating only one image, XY Plot should output only the image and skip the extra plot UI.

Only generate the XY plot visualization if multiple images are produced.

This would help make workflows cleaner.

Thanks!
