I have the actual time it takes a person to perform an action. Also I have the time you have to take.
How can I express these in the same graph with two dimensions? Location and type of action.
why don't you use a combo chart instead and define the second expression not as bar but us symbol.
This would bring you very near to your desired solution.
Hope this helps
This doesn't really help. But I think it explains this issue and suggests some alternatives in the comments.
