Hi
What have happend to my trendgraphs, look at the tempeture. Its all wrong, the year is 2099 and the data is incorrect (not 2009 years data). I have added data to my cumulus/data folder, from 1961 to today in the dayfile.txt and day-by-day (ex. dec04log.txt). Somehow that must have taken out the Cumulus trendchart. But how can I fix it ?

Check your dayfile.txt carefully. There must be a bad date (or empty record) somewhere in it.

Also, you may have problems with pre-2000 data. Cumulus has a deliberate built-in Y2K "bug" where it assumes that all data is 2000 onwards (since it didn't exist until 2003).

Aha, I have a lot off data before year 2000. Hm...can you fix that in the new Cumulus or should I delete the data ?

I think you'll have to take it out for now. I don't think there are any such restrictions in Cumulus 2.

Deleted all the data from 1961 to 1999 and the graphs are OK now.

Out of curiosity, where did you get all the data from?

Got it from our weather service her in sweden, SMHI.se. They have some weatherdata that is more than 150 years old. Free to download. But is just from some of the weather stations here in Sweden, not all. Pretty cool.
