Ack. After thinking some more, this is logical. You have 15 times
a counter increment.

No, it ALWAYS computes an average/max/min depe

No, it ALWAYS computes an average/max/min depending on what you set
in the rrd. Also, you NEED to
Thanks Alex! With your help I think I've got it all figured out.

Hi,
I have a RRD that was defined as follows:
rrdtool create $sensor.rrd -s 3600 \
DS:minutes:ABSOLUTE:3600:0:60 \
RRA:MAX:0.5:1:4800
Once per minute the RRD is updated with a 1 if my boiler is running, or a 0
if it is not. From that I can easily make a pseudo bar graph showing h
