I had forgotten that, in the absence of anything else, XType plot
aggregations leverage individual scalar aggregations. So, to plot
historical highs and lows, I didn't have to write any code, just get the
skin.conf spec right. Using this:
[[[yearhilow]]]
image_width = 800
image_height = 500
[[[[hi]]]]
data_type = outTemp
aggregate_type = max
label = High
[[[[low]]]]
data_type = outTemp
aggregate_type = min
label = Low
[[[[hist_hi]]]]
data_type = outTemp
aggregate_type = historical_max
marker_type = cross
line_type = none
label = Historical High
[[[[hist_lo]]]]
data_type = outTemp
aggregate_type = historical_min
marker_type = cross
line_type = none
label = Historical Low Temperature
yields this. This is for 12 years of data.
