Inflation ups and downs

Like most Americans, the only price I've been keeping track of this summer is of a gallon of gas. But a recent headline led me to an Atlantic article last month with some nifty graphs showing the dip in core PCE inflation. I remember the first worrying dip in fall 2010 because I mentioned it to undergrads. Crazy. I wonder if inflation expectations show a similar set of dips; the article seems to suggest they don't reflect the recent dip.
