Suppose you have a bar chart. When we group by labels in a view, which of the following happens?
A . Nothing changes in the view, but a group is created in the Dimensions shelf.
B . The colours of the members selected are now the same, and different for the rest of the members.
C . Trick question! It is not possible to group by labels.
D . A new mark (bar) is created, which consolidates all members of the group.

Then on grouping, a new bar is created, and the colour of all bars remain the same.

Had we grouped by choosing the marks instead of the labels, the following would be the result:
