My experiments confirmed this as well. Using specific timestamps, everything worked fine, but using N caused the NaN values to be stored as 0. Here you can compare the same data being entered into the RRDs (the same exact script is used). One rrd was made with 1.0, the other with 1.2. Both rrds are updated using 1.2. The 1.0 rrd: http://tepedino.org/rrd/weather-clt.php The 1.2 rrd: http://tepedino.org/rrd/test/weather-clt.php Same update scripts, same graphing scripts, same create scripts, except I changed which version created the rrd in each case. If you want, I can provide the scripts used, but I think Ralf's script was a simpler proof of concept. -- Salvatore D.
