As an example of how to use the addin, open the attached file. Then, select the addin from your addin menu, and cast the columns into the following roles:
Cast Amount into the Y role.
Cast Category into the Measurement Type role. This serves as a way to summarize the various entries.
Cast Group into the Group role, which is optional.
At this point the Category role is not optional. To "defeat" it, use a character column whose entries are unique for each row.
