Yes, I think the sliding window average (TREND) could work for me. So I need
to define a 24 hr sliding window to plot 24 hr averages? Is the TREND curve
same as if I graphed this: GPRINT:Inside:AVERAGE:"\t%6.2lf °C" (on the
picture on my last post)? Erik De Mare: how do you graph the averages for
each day?
