A Group is a "collection" of arbitrary objects, for which Colorbar is
not designed since it attempts to find the range of the data then do
an intelligent map. Obviously, in an arbitrary group, say a text
object, a camera, a light, and a data field, this makes no sense.
Change your Group to a Series (probably most appropriate in this data
case) or a Multigrid and it will work.
You could try simply using the ChangeGroupType module on the input or
rewrite your code.
