Hi, Short answer is no you cannot do that with the existing WeeWX plot engine. Longer answer; when plotting aggregates using the WeeWX plot engine each line you plot must use the same aggregate interval throughout. So you can plot an aggregate over an hour, a day or a week as these periods are all precisely and singularly defined. However, you cannot aggregate over a month or a year as whilst these intervals are precisely defined they vary from month to month (28, 29, 30 or 31 days) and year to year (365 or 366 days). The best you could do would be to create a plot with an aggregate period of 365 days (or 366 days), but of course this will only be an approximation and I suspect you may have some issues having your 365/366 day interval align even remotely close to the actual calendar year.
You could of course write a custom image generator to do this but that would involve substantial effort.
