I remember being intrigued back in the day about how did the Graph Plotter node in Unreal Engine worked.
I always saw that due to the uneven UVs aspect ratio it created glitches, stretching the plotting line.
This is obviously a minor issue, but I tried to research how to avoid this.
It turns out that using the gradient of the function can fix this, because it creates a "height map" following the line of biggest grow.
The maths behind this require a good background in algebra and it is very nicely explained in the following link at Iñigo Quilez website (a great source of computer graphics knowledge).

He also implemented it very nicely in this link:

I will have a look in the future at filly implementing this in Unity.
Have a great rest of your day,
