curves.json.tmpl is a custom template I made to use with Chart.js
It's all working now!
{ "current" : { "datetime" : "$current.dateTime.raw"},
"monthly": [
#for $m in $range(12)
{
"month": "$month($months_ago=$m).dateTime.format('%B')",
"min": $month($months_ago=$m).outTemp.min.nolabel('%.1f'),
"max": $month($months_ago=$m).outTemp.max.nolabel('%.1f')
#if $m < 11
},
#else
}
#end if
#end for
],
"last24": [
#for $_span in $span($hour_delta=24).spans(interval=1200)
{ "datetime": "$_span.start.format('%r')", "temp":
$_span.outTemp.avg.format(add_label=False), "dewpoint":
$_span.dewpoint.avg.format(add_label=False), "humidity":
$_span.outHumidity.avg.format(add_label=False), "windchill":
$_span.windchill.avg.format(add_label=False), "heat_index":
$_span.heatindex.avg.format(add_label=False), "barometer" :
$_span.barometer.avg.format(add_label=False) },
#end for
{ "void_end" : null }
]
}
