You've no doubt noticed that the Graph Editor in After Effects treats position…graphs differently than it does graphs for other values.…For example, when the display is set to Auto-Select Graph Type, for other values…it shows the value graph, but for position, it shows the speed, or velocity graph.…This is because it's bundling the X and Y coordinates--and if it was in 3D space…the Z coordinates, as well--into one keyframe value, and then calculating what is…the composite speed for changes in all of those dimensions at once.…
I'll select Snowstorm Title so I can focus on just a position graph.…Now I can indeed look at the Value Graph for position, and I can see a separate X and Y graphs.…However, I'm kind of limited in what I can do with them.…For example, if I hold the Command key down and hover the cursor over the graph…to add a keyframe to the Y graph,…it also adds a keyframe to the X graph.…You'll notice that I can't select just one keyframe without its partner…dimension being selected at the same time.…
