IMHO if a chart is what you're after then this is a job for Excel, especially since your query result resembles a spreadsheet anyway. Database information should be tall (in rows) not wide. Did you study normalization before beginning this task? Anyway, Access charts are only slightly better than having sand in your eyes, and what you show looks like you're playing with coloured rectangle widths, which just doesn't make sense to me (for this job).
The more we hear silence, the more we begin to think about our value in this universe.
