Google seems to be testing a "price history" chart or graph in the Google Shopping search product listings interface. I personally cannot replicate this yet, outside of seeing the "typical pricing across the web" section, but I do not see the price chart.
This was spotted the other day by Saad AK on Twitter who shared a video screencast of it in action. Here is a screen capture of just the price history graph that you can click on to enlarge:

I saw the "Price history" feature in a Shopping listing.
I am pretty sure that this is new. I haven't seen it before.
