Plot Config: Header/Footer (lab)

Most XY plots fit on one grid, and then some don't - you've varied enough combinations that the result paginates, and now each page needs context so you can tell what you're looking at. Plot Config: Header/Footer (lab) is the ComfyLab node for that job: it styles a page header or footer, with text that can show the current page number. It's the companion to Plot Config: Grid (lab), and it's what makes multi-page plots legible instead of a mystery stack of grids.

How it works

It emits a plot_config_hf output of the custom PLOT_CONFIG_HF type, and you wire it into XY Plot: Render (lab)'s plot_config_header or plot_config_footer input - the same node feeds either slot, so you'd use two instances if you want both. Render reads it when assembling each page. Like its sibling, it's a pure config node: no effect until it's plugged into a Render.

The inputs that matter

• text_left, text_center, text_right - the three text regions. This is where the pagination magic lives: each accepts the placeholders {current_page} and {total_pages}, so Page {current_page}/{total_pages} in text_center gives you a running page count.
• background_color (default transparent) - the header/footer's own background. transparent means "use the grid background," which is the sane default; set a hex or color name if you want a distinct band.
• font (default Roboto-Bold.ttf) - one of the four bundled Roboto faces or a full path to any TTF on disk.
• font_size (default 60) and font_color (default #222) - the text styling.
• padding (default 30) - vertical breathing room above and below the text.

That's the full set: three text fields, one background, three type controls, one pad.

Gotchas

The {current_page} / {total_pages} placeholders only work in this node's text fields. Don't confuse them with the {dim1} / {dim2} templating on the Render node's header-format widgets - different placeholders, different jobs (dim values vs. page numbers). Also, the page counter is only interesting if you've actually enabled pagination on the Queue node's dim1: max per page / dim2: max per page widgets; with pagination off, {current_page} is always 1. Not a bug, just physics.

Install

Standard pack install:

cd ComfyUI/custom_nodes
git clone https://github.com/bugltd/ComfyLab-Pack.git
cd ComfyLab-Pack
pip install -r requirements.txt

Or ComfyUI Manager → ComfyLab Pack, then restart ComfyUI. No model downloads; opencv-python is the pack's only heavyweight dependency. If headers feel like overkill for a single-page grid, skip it - the node earns its place the moment you're printing multi-page LoRA or checkpoint comparisons.
