[rrd-users] Mu graphs are incomplete

First of all an apology for my bad english, but is not my native lenguage.

I use scripts in bash to create several graphs about the flow in my network.
The version of my tools are:

- Ubuntu Server 8.04
- RRDtool 1.3.1
- IPFM 0.11.5

I defined the RRA's like this:

   rrdtool create $HOSTDIR/$i.rrd -s 300 \
      DS:In:GAUGE:600:0:U \
      DS:Out:GAUGE:600:0:U \
      DS:Total:GAUGE:600:0:U \
      RRA:AVERAGE:0.5:1:600 \
      RRA:AVERAGE:0.5:6:700 \
      RRA:AVERAGE:0.5:24:744 \
      RRA:AVERAGE:0.5:288:797 \
      RRA:MIN:0.5:1:600 \
      RRA:MIN:0.5:6:700 \
      RRA:MIN:0.5:24:775 \
      RRA:MIN:0.5:288:797 \
      RRA:MAX:0.5:1:600 \
      RRA:MAX:0.5:6:700 \
      RRA:MAX:0.5:24:775 \

And the graphs like this:

rrdtool graph $GRAPHDIR/$i.gif --end now --start end-480m --width 600
--height 250 \
   --title "HOST $i" --vertical-label "Bits por segundo" --watermark ZETA \
   --color CANVAS#000000 \
   --color BACK#000000 \
   --color FRAME#000000 \
   --color FONT#FFFFFF \
   --color ARROW#E70C0C \
   --lower-limit=0 \
   DEF:hostIn=$HOSTDIR/$i.rrd:In:AVERAGE LINE1:hostIn#0881C6:"Bytes In		"   
   GPRINT:hostIn:MAX:"Max %lg%s" \
   GPRINT:hostIn:AVERAGE:"Average %lg%s\\n" \
   DEF:hostOut=$HOSTDIR/$i.rrd:Out:AVERAGE LINE1:hostOut#B80D77:"Bytes Out	
"   \
   GPRINT:hostOut:MAX:"Max %lg%s" \
   GPRINT:hostOut:AVERAGE:"Average %lg%s\\n" \
   DEF:hostTotal=$HOSTDIR/$i.rrd:Total:AVERAGE LINE1:hostTotal#508B1D:"Bytes
Total	" \
   GPRINT:hostTotal:MAX:"Max %lg%s" \
   GPRINT:hostTotal:AVERAGE:"Average %lg%s\\n" \

But i can't make it look fine, because is not completely filled. I add an
image so you can see the result


There are minutes or even hours without data, and i'm shure there is
information to show because y keeps the text dump of ipfm as a history.

If you have any idea why this happens I would appreciate your help.

Thanks in advance!
