rrd如何画反坐标的图？

Question

类似附件的这种正反坐标都有的图怎么画？

/usr/local/rrd/bin/rrdtool graph -s 1195688000 /db/htdocs/sys/mon/speed.png -t "Only a test" -v "bits per second" -w 880 -h 600 COMMENT:"Last update time:`date |awk '{gsub(":",";",$0);print $0}'`c"
-b 1000
--alt-autoscale-max
--rigid
--lower-limit=0
--slope-mode
--font AXIS:7:
--font LEGEND:7:
--font UNIT:7:
DEF:in_bytes=/home/t/speed.rrd:IN:AVERAGE
CDEF:in_bits=8,in_bytes,*
AREA:in_bits#00CF00:"Inbound ":STACK
GPRINT:in_bits:LAST:"Current:%8.2lf %sbps"
GPRINT:in_bits:AVERAGE:"Average:%8.2lf %sbps"
GPRINT:in_bits:MAX:"Maximum:%8.2lf %sbpsn"
DEFut_bytes=/home/t/speed.rrd:OUT:AVERAGE
CDEFut_bits=8,out_bytes,*
AREAut_bits#002A97:"Outbound":STACK
GPRINTut_bits:LAST:"Current:%8.2lf %sbps"
GPRINTut_bits:AVERAGE:"Average:%8.2lf %sbps"
GPRINTut_bits:MAX:"Maximum:%8.2lf %sbpsn"

比如我想把out_bits画成反坐标的，该怎么改呢？

刚才写错参数
--rigid
--lower-limit=0
这两个弄掉就行了。呵呵。
