rrd graph not showing in trends

[Matt]

Finally kind of figured out this fancy rrd graphing business (oh man is 
it sweet).  Problem though, I can't seem to get my graph to populate in 
the trends column - it will populate in it's own column (should the 
client use the status channel).  Here are the relevant parts of each 
config file.

# Prepare to send message

DATA="data $HOST.$TEST
cpu1: $FAN1

# Send message

#$BB $BBDISP "$LINE"
$BB $BBDISP "$DATA"


Like I said, if I change the above client-side script to send via status 
channel, I get the graph.  If I leave it on the data channel, I get 
nothing - not even a link to an empty page.

If anyone could shed some light on this I'd appreciate it greatly,

Matt
