import rrdtool
import time
title="Server network traffic flow ("+time.strftime('%Y-%m-%d',time.localtime(time.time()))+")"
"MINUTE:12"
"HOUR:1"
"HOUR:1"
"0:%H"
rrdtool.graph(
"Flow.png", "--start","-ld","--vertical-lable=Bytes/s",
"--x-grid","MINUTE:12:HOUR:1:HOUR:1:0:%H",
"--width","650","--height","230","--title",title,
"DEF:inoctets=Flow.rrd.eth0_in:AVERAGE",
"DEF:outoctets=Flow.rrd:eth0_out:AVERAGE",
"CDEF:total=inoctets,outoctets,+",
"LINE1:total#FF8833:Total traffic",
"AREA:inoctets#00FF00:In traffic",
"LINE1:outoctets#0000FF:Out traffic",
"HRULE:6144#FF0000:Alarm value\r",
"CDEF:inbits=inocets,8,*",
"CDEF:outbits=outoctets,8,*",
"COMMENT:\r",
"COMMENT:\r",
"GPRINT:inbits:AVERAGE:Avg In traffic: %6.21f %Sbps",
"COMMENT: ",
"GPRINT:inbits:MAX:Max In traffic: %6.21f %Sbps",
"COMMENT: ",
"GPRINT:inbits:MIN:MIN In traffic: %6.21f %Sbps\r",
"COMMENT: ",
"GPRINT:outbits:AVERAGE:Avg Out traffic: %6.21f %Sbps",
"COMMENT: ",
"GPRINT:outbits:Max:Max Out traffic: %6.21f %Sbps",
"COMMENT: ",
"GPRINT:outbits:MIN:MIN Out traffic: %6.21f %Sbps"
)

最后一行报错rrdtool.OperationalError: start time: There should be number after '-'

求大神解答一下，不胜感激
