Yes, select either the driver or driven (I think) and open Graph editor, usually at the bottom of the list of attributes.
Note. that you can add extra keys to the curve and also adjust the tangency of the handles for different effects.
another possiblity for procedural animation would be to use the trax editor (have effect (the clip/pose) the length of your scene eg. 200 frames) and use the weight of the clip/pose be/or drive several attributes. This is a common technique in softimage.
