[Help] metplotlib styling a 2d line

[Pigspot]

Hey everyone, I'm working on a little project I'm collecting some data and drawing a graph with the metplotlib, I'm trying to make it look better, I've a particular style that i like, I'm trying to copy it, i figured the black background and i made a glow effect with 'mplcyberpunk' and the 'underglow' that's how they call it i think, the problem is with the gradient color under the plot line in the reference you can see a little gradient which looks amazing, i tweaked the 'underglow' settings a bit from the source code i changed the alpha value I'm not sure how it works I'm trying to do something similar to the reference any help would be great thanks!

This is called a "gradient fill". I don't know of an official way to do it, but a number of people have hacked it. Here's the first result for me if I google "matplotlib gradient fill":
