[rrd-users] Averaging Question

I'm wondering if this is possible with rrdtool:
I have a sensor which is logged once every 30 seconds.
I would like to produce a graph on which each point represents a 15 min
average of the sampled data.
Here is the caveat: The graph should have as many points as there are 30
second data points with each point representing the average of the previous
15 minutes worth of data points. So a sort of "running average" if you will.
I'm guessing some DEF or CDEF magic will be needed to do this.... but I'm no
statistics guru. :-)
