XY Plot Pixaroma

What it does

Drop this at the end of your workflow and wire your final image into it, like a Preview node. Pick what changes ACROSS (X = columns) and DOWN (Y = rows), press Run once, and every combination fills a labeled grid right here on the node.

How to use

• Wire your workflow's final image into the image input.
• In the X card, pick a setting to vary across the columns. Do the same in the Y card for the rows (you can use just one axis if you like).
• Enter the values you want to try in the value box.
• Press Run once. The grid builds as each run finishes.

The value box adapts to what you pick

• The checklist shows ALL your installed options (every lora, sampler, checkpoint, etc.), not just the one in the node - that is how you compare against ones you have not loaded yet. The now: line under the picker shows what the node is set to right now.

Number

A Range (Start / End / Steps) or a List of values.

Dropdown

A checklist of VALUES to try, not a list of things to load at once: tick the samplers / models / loras you want to compare and each tick becomes one square.

LoRA

A checklist of lora files, or a number when you pick a weight. Loras get a section of their own further down, because they work one level differently from every other setting.

Prompt text

Full list (one full prompt per line) or Find & replace (swap a word for each value). Long prompts wrap onto several rows, and the numbers down the left count your VALUES, so you can always see where the next one starts. The numbers are just a guide - you cannot type in them.

Examples: what to pick for what you want

Two things to hold on to and the rest follows. The picker chooses WHICH setting changes. The value box under it chooses WHAT that setting becomes, and you get one square per value, not all of them at once.

So X and Y are how many settings can change at once, not how many things you can compare. One axis with 5 ticks gives you 5 squares, and you can go up to 100 on an axis. Use the second axis when you want a SECOND setting changing as well.

Two habits worth having. Watch the counter above the buttons, because it tells you how many images you just asked for and 4 across by 3 down is 12 runs. And leave Lock seed on unless you are plotting the seed itself, or two things change at once and you cannot tell which one did it.

Which sampler suits this image?

X: your KSampler's sampler_name. Tick the 4 or 5 you actually use. One row of squares, one sampler each.

How many steps do I really need?

X: steps, Range, Start 10, End 40, Steps 4. That gives 10, 20, 30, 40, and you can see where it stops improving.

Steps against cfg, all at once

X: steps (try 15, 25, 35). Y: cfg (try 3, 5, 7). Nine squares showing every pairing, which is far quicker than nine separate runs.

Same prompt, one word different

Pick your prompt text and choose Find & replace. Put the word to swap in Find, and your alternatives in the values. Everything else in the prompt stays put.

Which checkpoint handles this prompt best?

X: your checkpoint loader's ckpt_name. Tick the models to try. Turn Lock seed on so the seed is not also changing.

Comparing LoRAs, case by case

Loras trip people up more than anything else here, because they sit one level deeper than the other settings. Your lora loader has ROWS. An axis changes ONE row. The list you then tick is every lora on your computer, and each tick is one square. So the row you pick is WHERE the change happens, and the ticks are WHAT goes there.

Just one lora in the loader

The easy case. Pick LoRA 1 file and tick as many loras as you want to see. Each square runs exactly one of them, with nothing else muddying it.

Two or more loras in the loader

The axis still changes only the row you picked. Every OTHER row that is switched on is applied in every square, which can hide the thing you are comparing. Switch off the ones you are not testing. If one would get in the way, an orange line under the picker tells you which.

Keeping a lora in every square on purpose

Sometimes that is exactly what you want: a style lora you always use, while you compare something else. Leave its row on and read the grid as A plus style against B plus style.

What weight should it be?

Pick LoRA 1 strength and enter a list like 0, 0.4, 0.7, 1. The 0 square is your before shot, because a lora at 0 does nothing at all.

Which lora AND at what weight

X: LoRA 1 file with your candidates. Y: LoRA 1 strength with a few weights. Every lora at every weight, in one grid.

Two loras mixed together

X: LoRA 1 file. Y: LoRA 2 file. Here you WANT both rows switched on, since every square is a real pairing, so no warning appears.

Three rows all changing at once

Not possible, since there are only two axes and so at most two settings can change. Keep the third row fixed and switched on, or run a second plot.

Trigger words

When you swap the FILE on a LoRA Loader Pixaroma row, that row's ticked trigger words are left out of every square, because they belonged to one particular lora. Put any words you want in all squares into your prompt instead.

Which entries you get

With LoRA Loader Pixaroma each row appears as LoRA 1 file and LoRA 1 strength, counted from the top of the node, plus LoRA 1 clip strength when model and clip are separate in the gear. The core Load LoRA node and other multi-lora loaders work too.

Entering numbers

• List: values separated by commas, e.g. 5, 6, 7.1, 10. Decimals are kept exactly.
• Range: set Start, End and Steps (how many). 5 to 15 in 3 steps gives 5, 10, 15.
• Shorthand inside a list also works: 4-10 (+2) steps by 2, and 4-10 [4] gives 4 evenly spaced values.

Buttons and options

Lock seed

Keeps the seed the same for every square so the only thing changing is what you're testing. Turns off on its own if you're plotting the seed.

Draw labels

Show the value labels and axis names on the grid.

Save cells

Also save each square on its own, not just the whole grid.

Grid: Dark / Light / Mono

The grid background and label style. Switching re-skins the grid you already have, instantly.

Reset X / Reset Y

Clear just that one axis.

Reset XY

Clear both axes and all selections, back to a fresh node.

Save Disk / Save Output / Copy / Open

Act on the finished grid: save it to your computer or to ComfyUI's output, copy it, or open it in a new tab.

Saving and image size

The grid shown on the node is a preview, capped at 4096 pixels on its long side so it stays light. The Save row picks how big the SAVED file is:

• The full-size grid is built only when you click Save, so choosing a bigger size never slows your runs down.
• Save Disk saves to your computer and Save Output goes to ComfyUI's output folder, both at the Save size. Copy and Open use the smaller on-screen preview.
• The grid sent out of the node's image dot (top right) always stays 4096, to keep anything wired after it fast.
• Want the preview bigger on the canvas? Make the NODE wider and it grows with it (and smaller again when you narrow it). A very tall grid stops growing at a point, so the node stays a size you can still work with - use Open for a proper look at that one.

2048 / 4096 / 8192

Cap the exported grid to that many pixels on its long side.

Full

Export at native resolution, every cell at its real size. This makes the largest file.
