    Status: Open => Answered

Matthew Kemp proposed the following answer:
Function Definitions:
Integral - This function creates new series whose values represent the growing sum of the values of the original series over time.

Cumulative - Normally when you request a graph whose time interval
covers more data points than pixels you have to draw with, the series'
values are consolidated by averaging them together so that there are few
enough data points to draw in the available area. For some metrics, like
say number of requests, which are inherently integer values, averaging
may not be the desired means of consolidation. While averaging does give
meaningful information, that is the average minutely number of requests
which occurred in some larger time interval, this may not be what you
desire. You may use the cumulative function to change the consolidation
method of a series to be summing instead of averaging, which would yield
the total number of requests which occurred in a given interval.

I thought this stuff was on http://graphite.wikidot.com, but I may be
wrong.
