Following the flow of the comic, the reader is led to think that Cueball is angry at his wife about their relationship, accentuated by the "relationship graph." Subsequently, the wife says that the decline is actually due to Cueball's out-of-control fascination with graphing, to which he responds (unwittingly?) with "correlation does not mean causation".

A Fourier transform breaks down the graph into periodic components. A spike at 1-month on the Fourier transform would mean that something happens every month that causes the relationship to decline. This is unlikely to be related to lunar cycles.

Fourier transformations were mentioned previously in xkcd.


[Cueball is pointing at a line graph at a specific point where it slopes down. The Y Axis shows that as Y increases, Love increases.]
Cueball: "Our relationship entered its decline at this point."
Megan: "That's when you started graphing everything."
Cueball: "Coincidence!"

Indeed, plus the notion that Cueball had begun graphing everything at a particular point while prior data had been graphed suggests that he only began presenting this data to Megan at that point, and had been secretly, perhaps obsessively, keeping data well before in their relationship.

isn't it a bit speculative to add this to "comics featuring megan"? I'd "be bold" and remove it from there but I don't know how to. 01:06, 6 April 2015 (UTC)
