how to set custom graph commands(cur, avg, max, min)

Hi
I have a qustion.

zenoss version : 4.2.4

this is my rrd set.
->
RRA:AVERAGE:0.5:1:24000
RRA:AVERAGE:0.5:6:24000
RRA:AVERAGE:0.5:24:24000
RRA:AVERAGE:0.5:288:24000
RRA:MIN:0.5:1:24000
RRA:MIN:0.5:6:24000
RRA:MIN:0.5:24:24000
RRA:MAX:0.5:1:24000
RRA:MAX:0.5:6:24000
RRA:MAX:0.5:24:24000

I added graph definition and set custom definition

default graph command (when network device - graphdefinitions: packets) is
===========================================================================
-F
-E
--disable-rrdtool-tag
--height=100
--width=500
--lower-limit=0
--rigid
--vertical-label=packets/sec
