Hi everybody, i tried to read a data file with a 1/4 h time interval of average data in a 1 min simulation. If I set "Averareous or instantenous value" to "average" I got some wrong curve and the values seemed to be mirrored on the x axis. Can anybody help me to better understand the behanviour of type 9? P.S: I doesnt seem to depend on the data reader mode... Many thanks, Stefan
