I can't think of any way to do that with the existing reporting machinery
without writing some pretty fancy custom search list extensions. Frankly, I
think a SQL query would be easier. Even that would require some serious
SQL-foo.
Easiest would be to write a simple Python program that runs once a
Hi Tom,
Sorry, I was thinking in unixtime meaning an hourly datetimestamp and
making such a graph once per day, week or even month would be plenty. You
are correct that I could make a script outside of weewx to query the
database and spit this out. Was trying to keep it all within weewx. What I
I'm not completely understanding your question. You say you want one hour
averages, but your example has only one value per date. I would expect 24.
Also, is this something you want to produce every archive cycle? Or, only

Hi Tom,

Unfortunately, neither of those are possible with the present image
generation engine.
You could run wee_reports, using a timestamp of a year ago, saving the
images to a separate spot. Then you would be able to display this month's
graph, and the same month a year ago. But, they would be in separa
I have a couple questions about image generation that doesn't seem to be
covered in the docs anywhere.
I would like to be able to create images with the same data value, but from
multiple time ranges. For the yearly say, have the last 365 days as one
line, but then have another line that has th
