For some reason it stopped updating with last years temps? Is it something I may have un-ticked? I checked the data and it appears ok in the noaa detailed view.
humm, i have the same problem
investigating
i suspect its do with february being only 28 days…thats where i will look anyway!
(as its 4 days missing, which is 31-28)
i still need to find time to work on this
the problem is that this years data is the last 31 days data
but last years data is not that same period…i.e 31 days up to the current day, last year…
i need to do that…(will take a bit of work /workin out to build a 31 day data window , to the current day, from a set of data (i.e 2 months of data (i.e this month and last month) 1 year ago)…I hope people dont think this month change/31 day/28 day data month stuff is easy
Well Brian, I for one and I’m sure there are many others that do realize that none of what you do for support and improvemnt of WD is “easy”.
It’s absolutely something I can’t do at all. So it sounds “hard” to me. 
Thanks buddy for your dedication.
when i made the wind temp rain trend always last 31 days, i did not at the time convert last years data to that format as well…
so thats my next project…amoung other things!
I just had to think about how best and easiest way to do this while at the beach…
i used the code i already had to recreate the last 31 days data file,…for data from 1 year ago…into a temp data…
and it works

I think I may be missing data from last year for the temp, will have to check that when I get home from work. But the rest of the graph looks to be working. Thanks for the update/fix.
I haven’t figured out how to get the feb graph to show all the data…see attachments
Jan data looks ok but Feb is missing data. I tried rebuilding the reports and converting and rebuilding 31 days with no luck…
ah,if you change the month…i dont have it re creating the data for last year based on that new month…from memory…i will check on that!
Ok, looks even worse now with my playing around…Jan2006 appears very flat on the chart, stuck around 44
just fixed up the windspeed plot for last year for the 1st and last data points being wrong, with this update:
