I took prt of a sample graph from my cacti (rrd frontend) installation
to show how it work for me:
GPRINT:cdefa:LAST:" Current\:%8.2lf %s" \
GPRINT:cdefa:AVERAGE:"Average\:%8.2lf %s" \
GPRINT:cdefa:MAX:"Maximum\:%8.2lf %s\n" \
GPRINT:cdefe:LAST:"Current\:%8.2lf %s" \
GPRINT:cdefe:AVERAGE:"Average\:%8.2lf %s" \
This defines an Area (Inbound) with Current: nnnnnn.nn Average:
nnnnnn.nn Maximum: nnnnnn.nn Values as well as a Line (Outbound) with
same values leftbound. Both legends fill a single line of text each.
