<P><FONT SIZE=2 FACE="Arial">Hi,</FONT>
</P>
<P><FONT SIZE=2 FACE="Arial">I have been capturing data for approximately 2 weeks now for JVM heap usage and am trying to get last week's data in one line</FONT></P>
<P><FONT SIZE=2 FACE="Arial">and the weeks before on another line within the same graph. This is good to be able to see what the difference is between the 2</FONT></P>
<P><FONT SIZE=2 FACE="Arial">weeks and perhaps from 1 month ago as compared to last week.</FONT>
</P>
<P><FONT SIZE=2 FACE="Arial">Version I am using: rrdtool-1.0.49</FONT>
</P>
<P><FONT SIZE=2 FACE="Arial">1.</FONT>
<BR><FONT SIZE=2 FACE="Arial">I created the rrd database using the following command</FONT>
</P>
<P><FONT SIZE=2 FACE="Arial">/usr/local/rrdtool-1.0.49/bin/rrdtool create jvm_heap.rrd \</FONT>
<BR><FONT SIZE=2 FACE="Arial">DS:SnapShotAvg:GAUGE:600:U:U \</FONT>

</P>
<P><FONT SIZE=2 FACE="Arial">2.</FONT>
<BR><FONT SIZE=2 FACE="Arial">I then tried to create a graph with 2 different weeks in the same graph using the following command</FONT>
</P>
<P><FONT SIZE=2 FACE="Arial">/usr/local/rrdtool-1.0.49/bin/rrdtool graph jvm_comp.png --step 3600 --width 600 --end now --start end-1w \</FONT>
<BR><FONT SIZE=2 FACE="Arial">DEF:SnapShotAvg=$BASE/$RRF.rrd:SnapShotAvg:AVERAGE \</FONT>
<BR><FONT SIZE=2 FACE="Arial">DEF:SnapShotAvg1=$BASE/$RRF.rrd:SnapShotAvg:AVERAGE:end=now-1w:start=end-2w \</FONT>
<BR><FONT SIZE=2 FACE="Arial">LINE1:SnapShotAvg#267C8A:\"This Week Average\" \</FONT>
<BR><FONT SIZE=2 FACE="Arial">LINE1:SnapShotAvg1#992222:\"Last Week Average\" </FONT>
</P>
<P><FONT SIZE=2 FACE="Arial">All that I ever get, regardless of the time period I use above (I.E. Trying to compare today with yesterday on the same graph using -1d and -2d)</FONT></P>
<P><FONT SIZE=2 FACE="Arial">is one line in the graph. When I change the current week to an AREA and not a LINE, the second week simply runs along the top of the area</FONT></P>
<P><FONT SIZE=2 FACE="Arial">which to me looks like each output is showing exactly the same data as each other (which is --end now --start end-1w).</FONT>
</P>
<P><FONT SIZE=2 FACE="Arial">Can anyone shed some light as to what may be happenning here and why the second line is not showing up the data from the week before. </FONT></P>
<P><FONT SIZE=2 FACE="Arial">I have read something about SHIFT, but my version does not have this option available to me and I am unable to upgrade due to server access.</FONT></P>
<P><FONT SIZE=2 FACE="Arial">Thank you,</FONT>
