I am using rrdtool, libdbi, and mysql to chart thermal data.
I noticed the lines are sometimes a little higher than the actual data
being plotted, and I would like them to match.
Is there something I can change to make the graphed data match the
actual data?

thank you for your help.

I did try both.
rrdtool graph ./test.png --imgformat=PNG --start=-1day --end=+3hours
--width=1000 --height=600

I am having a hard time finding the syntax for using a dbi with rrdtool
graph.
Command:
rrdtool graph ./test.png --imgformat=PNG --start=-1day --end=+0hours
--width=1000 --height=600
"DEF:min=sql//mysql/host=127.0.0.1/dbname=thermal/username=thermal/password=thermal//temperature/date/cpu0:min:AV
I would like to start tracking the growth of my source control server,
starting with data from 2007. For each repository, on a given date, I
have its size and revision number, and I have a perl script to pack all
the historic data into one big hash table.
I am wondering if I rrdtool can be used
Is it a mistake to want to plot the difference between stored data
values?

I have a graph which shows the size of my server backups.
I would like to add to the ledgend (and maybe graph) the change in size
from the last backup.
Do I define a vdef for size,LAST and a vdef for LAST-1,
then calculate a cdef of the difference
then a vdef of cdef of the difference,
and fina

I have a rrd with values like: 5.3304700563e+07
My gprint line is:
GPRINT:backup1: %10.3lf %Sb'
I'm trying to print: 53.305 Gb
but it always prints: 53.305 Mb
What am I doing wrong?

I need help to understand why my rrd won't accept data from my updates.
This is to chart a number once a day.
At the end of my backup script, if the rrd does not exist, it is created
via the following:
rrdtool \
create \
"${RRD_File}" \
--step 86400 \
"DS:size:GAUGE:87000:U:U"
