Hello,

Is there nobody that can help me ? I tried to make a graph with the
following command, to make sure the start and end were not involved :
rrdtool graph test.png --width 550 --height 150
DEF:Power=pv_monitor.rrd:PAC:MAX LINE1:Power#FF0000: -u 3000 -v Watt -t
hallo

Same result : on the new installation no data in the graph, the old
installation's graph is OK.

I'm going to try to include the pictures, first the good one : test-ok.png


Regards,

Koenraad Lelong.
