thanks sigma. I watched a vid explaining the graph editor for beginners, and the dude said that X axis of the graph editor is time (like, how long the animation takes). And the Y axis was the "value of the keyframes" which I didn't understand. From what he demonstrated, it looks like it's the speed at which the bones move (and adjusting the slope of the line can make the animation start slow, build speed, etc to ease in or out of movement) but idk why he didnt just say that first
