[rrd-users] Re: Inaccurate graphs

[michael t. anderson]

Okay, I have tweaked my input script to always return 210000000000 for the
second (total disk size) variable. Now it is totally clear that RRD is not
graphing this properly or the Y axis is mislabeled or something else is
wrong because the red line should be right on top of the 210 G gridline.
I've attached a graph which shows this problem. Here is the rrd dump:
<!-- 2004-03-23 23:40:00 PST / 1080114000 --> <row><v> 1.9036134523e+11
</v><v> 2.1000000000e+11 </v></row>
<!-- 2004-03-23 23:45:00 PST / 1080114300 --> <row><v> 1.9036655601e+11
</v><v> 2.1000000000e+11 </v></row>
<!-- 2004-03-23 23:50:00 PST / 1080114600 --> <row><v> 1.9036677915e+11
</v><v> 2.1000000000e+11 </v></row>
<!-- 2004-03-23 23:55:00 PST / 1080114900 --> <row><v> 1.9037242655e+11
</v><v> 2.1000000000e+11 </v></row>
<!-- 2004-03-24 00:00:00 PST / 1080115200 --> <row><v> 1.9037716480e+11
</v><v> 2.1000000000e+11 </v></row> 

Does anyone know what's going on here?
