Graph editor editing?

No sure if I missed something here.
When animating rigs in pose mode though the 3D view the corresponding channels is changed in the graph editor to reflect this.
But when trying to do some curve tweaking in the graph editor these changes is not shown in the 3D view rig. Nothing is changed there.

What have I been missing?

Changing he keyframe values in the left side list does work but not changing value by moving the node in the graph…

Revive Disabled F-Curves is the remedy…
Took a lot of digging finding this.

Can you provide just a couple of sentences on what actions you took?
Thanks

In graph editor select Channel>Revive Disabled F-Curves.
