Hi Tom,
Is there a creative way that one could make a text file with the data? I'm
trying to figure out how to make a csv file with the last 5 years worth of
data.
Output CSV something like aggregate 1hr averages for outTemp
Date, outTemp.0, outTemp.1, outTemp.2, outTemp.3, outTemp.4
Date1, outTempcurrentyear, outTempyearN-1, outTempyearN-2, outTempyearN-3,
outTempyearN-4
Date2, outTempcurrentyear, outTempyearN-1, outTempyearN-2, outTempyearN-3,
outTempyearN-4
...
Date365, outTempcurrentyear, outTempyearN-1, outTempyearN-2,
outTempyearN-3, outTempyearN-4
This can then easily be plugged into javascript to then graph on the same
axis.
I can get 5 years worth of data our using either:
#for $_span in $span($year_delta=5).spans(interval=3600)
$_span.outTemp.avg.formatted,
#end for
<br>
{test aggregation 1 year ago}
#for $_span in $year($years_ago=5).spans(interval=3600)
$_span.outTemp.avg.formatted,
#end for
Having a hard time coming up with a loop structure that would allow the
desired output and would love any ideas on how to aggregate and loop
through the data to accomplish this.
