I find that the key to solving this sort of problem is more of a spreadsheet problem than a charting problem.
IMO, the best first step is to extract the desired subsets of the data from the main list. I never use Excel for database type work, but would expect you could accomplish this using filters, pivot tables, database functions, or lookup functions. I expect the result will look something like:
Once you have the each desired subset in its own block, then you can add each subset to the chart as its own series, and format each series as desired.
