Hi,
Excellent post. I used to be mad about graphing everything and this is a good excuse to get back to it.
I’ve gone for a 60 second step and added a trend of 2 Hours on the daily graph
CDEF:trend_cpm=cpm,7200,TREND \
AREA:cpm#00CCCC:"Count Per Minute\g" \
GPRINT:cpm:MAX:" Maximum \: %5.1lf " \
GPRINT:cpm:AVERAGE:" Average \: %5.1lf " \
GPRINT:cpm:LAST:" Current \: %5.1lf \l" \
LINE2:trend_cpm#000000:"Count Per Minute Trend 2 Hour\g"
