Hello, I still have problems with the PREV function... I modified the
rrd_graph.c source thanks to the Darren Kelly's code, I re-compiled rrdtool,
but it still seems to be not working for me...

Here is the shell script I'm running :
rrdtool create connection.rrd --start 1042196400 DS:connection:GAUGE:300:U:U
rrdtool update connection.rrd 1042196700:5 1042197000:5 1042197300:10
1042197600:5 1042197900:15 1042198200:10 1042198500:25 1042198800:20
1042199100:15 1042199400:15 1042199700:5 1042200000:10
rrdtool dump connection.rrd > connection.xml
rrdtool graph connection.png --start 1042196400 --end 1042200000 -w 800 -h
600 -a PNG DEF:connection=connection.rrd:connection:AVERAGE
CDEF:connection0=PREV,connection,+ LINE3:connection0#FF0000

Where is my mistake ? Thanks in advance !
