Identify this graph

A little bit of fun.  All you have to do is identify what this graph is charting out.  The x and y scales are linear.  It has something to do with coffee.  The first person to identify it will get a bag of tasty, tasty coffee sent to them from me.  Terms and conditions apply 1

Clearly I’ve made this too tough.  Here is the same graph with a little more information on the axes:

    Sorry if I misunderstand, this is then the inverse of an s-curve on a profile sheet? And then at about 9:30 it begins to rise again?

    I’ve been using live BT RoR graphing for about a year now. Looked familiar, forgot to factor the degrees C. Not sure how many roasters are graphing this but it sure gives a micro-look at a roast profile. With a more detailed graph you can even see the various amount of cracking highs and lows during 1st crack.
