Suppose I have a time series (say, for the sake of argument, the stock time series of AAPL for the last thirty years or so), and I want to mark (with some sort of a highlight, or flag, or whatever) pivotal events (Steve Jobs comes back, iMac released, iPhone released, etc). Is there a reasonably civilized way of doing that? This is a pretty common thing to do on Bloomberg terminal and such.
