Here are some explanations of what wOBA is
I aggregated this at the TEAM level rather than at the player level. Please correct us if you have any concerns about doing this at the team level.
Note: Credit where credit is due. Pulled this query down from Matt Dennewitz's github
Modified it slightly to group it by year/team/Home&Road/1st&2nd half of the season
This assumes you have loaded/imported the event files from retrosheet into your own database (ie, MySQL).

You can use a tool like MySQL workbench to run it. Then you can export it into a spreadsheet and graph it with Python and/or R or your favorite analysis language.
