I'm a writer and I've been looking for a solution that would make it easy to compare character timelines. In my mind, this would look like the following: I'd create the master chart with 200+ individual timelines as horizontial bars. The y axis would be the years. I could then place major milestone lines throughout the charts that represent major events (i.e. wars). Then when I want to compare two characters, I'd be able to simply filter the results to show character A vs. charcter B. I'm not sure how I'd want the filtering to work though I guess an autocomplete list would work best...
Does this sound like something jChartFX can do?
