Hi folks, I am wondering how to make a graph with the date and time of maximum value. Actually I do it this way: 'DEF:a_temperatur_max=/home/pi/wetter.rrd:aussentmp:MAX‘ \ 'VDEF:a_temp_max=a_temperatur_max,MAXIMUM' \ 'GPRINT:a_temp_max:max\: %5.2lf °C'
But would like to print the time of the maximum value also. Any hints? Jens-Uwe Bremeier
