Collection items out of order on multi-graph reports

The sequence specified in the collection definition of a multi-graph report isn't honored when the graph is built.

From Chet:

Add a bunch of individual devices to the same collection in a multi-graph report, re-order them.. add a graph and a graph group combine the graph and collection with "all devices on same graph" and verify that the order you put the devices in is maintained.

There is a section on the multi-graph reports in the admin guide that is decent.

Saw this working; thanks for the info on reproduction. Was able to view the graph as it was generated, then change the order in the collection set and view the changes on the graph when I navigated back to it.
