You should look a little closer, even if the documentation of rrdtool graph 
looks a little complicated.

Ok, a little hint, you've got to define the datasources you wish to see.
rrdtool graph test.png --start 01/12/03 --end 01/13/03 DEF:test= 

where 'test' is the datasource in your rrd-file. Change this to however your 
datasource is named. If you want to see two lines, you'll have two define two 
datasources and two lines and so on. To see how such an rrd database file 
looks like, try 
rrdtool dump d:\mrtg\isg999999sm3001\logs\isg999999sm3001-1.rrd
There you will also find the names of your datasources. Another way to find 
this out is 
rrdtool info d:\mrtg\isg999999sm3001\logs\isg999999sm3001-1.rrd

Just try a little and get back if you're stuck.

Best regards,
