I am using RRD tool to monitor CPU usage by Oracle database. My data 
source definition is DS:ds1:COUNTER:600:U:U. There is no problem with the 
graph if there is no negative value but if there is any negative value 
then I can see a sudden increase in the graph. How to avoid this in the 
graph whether I have to set any min or max in the data source or any other 
changes. Please let me know.

Sample value 

SNO     DATETIME                VALUE

43142   10-nov-2004 14:57:50    1665197
43147   10-nov-2004 15:06:01    669

Sample graph
