# LossGraphNode - ComfyUI Built-in Node Documentation

> The LossGraphNode creates a line chart of training loss values over training steps and shows it as a preview image.

The LossGraphNode creates a line chart of training loss values over training steps and shows it as a preview image. It reads loss values from a training node, plots them on a graph with labeled axes and min/max loss values, and returns the graph as an image preview in the UI.
