When I change the rotation of a certain bone (e.g. the bone of an upper-arm) in 3d view on only one axis (e.g. ' X '), all three curves in the graph editor are automatically changed when I set a keyframe and not only one curve.

Therefore, changing the rotation in the graph editor by changing the keyframes would be easier than to work in 3d view where all 3 axes are automatically changed. But since I work with Quaternion I would like to avoid using the graph editor to adjust the rotation of a bone because the W rotation wouldn't be automatically adjusted.

Is there a way to have the same effect when changing the rotation of one axis in 3d view as it is in the graph editor?

I think you are referring to inserting a keyframe for a single channel. Of course with quaternions the minimum number of axis are two (because how quaternions works) enter image description here

  • $\begingroup$ But that only seems to show the rotation on only the selected axes e.g. if I added the X rotation to the Keying Set and only change the Y axis, the X-curve will be affected. What I would like to know is how to affect only e.g. the X axis when rotating the bone by pressing R + X and not the other axes. $\endgroup$ – Eti2d1 Mar 12 '16 at 10:00
  • $\begingroup$ So the bone only moves to one direction. It's like you change the axes from global to local to have the chance to affect only one axis for the location. $\endgroup$ – Eti2d1 Mar 12 '16 at 10:07

    $\begingroup$ automatic Keying will write to all you channel, but if you press I for the following poses the box axis it'll keep inserting only in that channel. Or maybe I have not understood what you are asking for. It's rather confused to me... $\endgroup$ – diramazioni Mar 12 '16 at 12:49
  • $\begingroup$ As I wrote with quaternions the minimum number of axis are two (because how quaternions works) W + X or Y or Z $\endgroup$ – diramazioni Mar 12 '16 at 12:51

    $\begingroup$ sure select Local orientation then press R and double press X for a local rotation on X (same for Y and Z) $\endgroup$ – diramazioni Mar 12 '16 at 14:20
