Hmm, are you certain? I've just read through that (assuming you meant Alex vd Bogaerdts tutorial) and it doesn't get me any closer. I can graph when the temperature exceeds 24C etc. - no problems there. Perhaps I wasn't quite clear on what I need: Over a 30 day period (for example), I want a graph that shows the number hours per 24hour period in which the measured temperature exceeds 24C. Showing _when_ it exceeds 24C is no problem, but computing the _amount_ _of_ _time_ it did it, seems difficult? /Per Jessen, Zürich -- http://www.spamchek.com/freetrial - managed anti-spam and anti-virus solution.
