The only way to scale a group of keys on a curve is to use box selection by using control drag a box around desired keys, however, sometimes the X and Y tracks intertwine and I can't cleanly box select the desired keys to do the scaling. I see there is a Graph filter to filter out X and Y tracks but it doesn't seem to work. can someone help me with this? Thanks!
Graph editor filter
For a Translate timeline the X and Y keys always move together. They can have different values, but are on the same frame. Even when you only box select X or Y, both X and Y frames will move.
You can separate X and Y for a bone, then you'll get separate Translate X and Translate Y timelines:

This enables X and Y keys to be on different frames. You can then filter those using the graph visibility dots, to see only X or only Y.
Thanks! I believe I saw that and didn't realize what that was, now I know!
I believe it's exactly what I need.
Thanks!
Glad that helped!
Spine used to only have Translate timelines, without the ability to separate them. That has some benefits, so it's the default. Fewer timelines means fewer rows in the graph and dopesheet, less clutter for the animator. Also fewer timelines at runtime is slightly more efficient, but that effect is very slight, so you shouldn't generally keep them combined for performance reasons. It's more about the cumulative number of timelines, since if all translate/scale/shear timelines were separated needlessly it would double the total number.
