I applied the patch. Then I removed all the PNG files in the HTML
directory, that they need to be re-created. Then I re-started WeeWX and
waited for the next archive interval to come. I used Seasons skin.
There was no error message in syslog.
I checked all the plots in all time spans for their respective unit labels.
All the unit labels were correct, including that of the radiation energy
integral.
Please, could you include "energy_integral" in the list in line 185 of
imagegenerator.py together with "min", "max", and "avg" in order to put the
point into the middle of the aggregation interval for that aggregation
type, too?
