XY KSampler Plot

A custom ComfyUI node that generates a full XY grid of images by independently varying two parameters — LoRA selection, seed, LoRA weight, CFG, or steps.

Installation

ComfyUI/
└── custom_nodes/
    └── xy_ksampler_plot/   ← drop this whole folder here
        ├── __init__.py
        ├── nodes.py
        └── web/
            └── xy_ksampler.js

Restart ComfyUI. The node appears under sampling → xy_plot as "XY KSampler Plot 🎛️".

Inputs

Input	Type	Notes
model / clip / vae	standard	from your checkpoint loader
positive / negative	CONDITIONING	from your text encoder
latent_image	LATENT	from Empty Latent Image
seed	INT	base seed (overridden when axis = Seed)
steps	INT	base step count
cfg	FLOAT	base CFG
sampler_name	COMBO	e.g. euler, dpmpp_2m
scheduler	COMBO	e.g. karras, simple
denoise	FLOAT	1.0 = full denoise
base_lora	COMBO	LoRA applied when axis ≠ LoRA
lora_model_strength	FLOAT	model weight for base/axis LoRA
lora_clip_strength	FLOAT	clip weight for base/axis LoRA
x_axis	COMBO	Seed · LoRA · LoRA Weight · CFG · Steps
x_values	STRING	comma-separated values for X axis
y_axis	COMBO	None · Seed · LoRA · LoRA Weight · CFG · Steps
y_values	STRING	comma-separated values for Y axis
add_labels	BOOL	draw axis labels on the grid

---

Value format

Axis type	Format	Example
Seed	integers	0, 42, 1337
Steps	integers	10, 20, 30
CFG	floats	4.0, 7.0, 9.0
LoRA Weight	floats	0.5, 0.75, 1.0
LoRA	filenames	anima_v1.safetensors, anima_v2.safetensors

For LoRA axes, use the 📂 Pick X/Y LoRAs buttons that appear on the node — they open a searchable checkbox picker that fills the field automatically.

Outputs

Output	Shape	Description
grid_image	[1, H, W, 3]	assembled grid with optional labels
all_images	[N, H, W, 3]	every cell as a batch

Typical use: LoRA comparison × seed

x_axis  = LoRA
x_values = anima_char_eliza_v2_s10.safetensors, anima_char_eliza_v2_s40.safetensors, anima_char_eliza_v2_s70.safetensors

y_axis  = Seed
y_values = 0, 42, 1337

This produces a 3×3 grid: 3 LoRA checkpoints across columns, 3 seeds down rows.
