[Orca-users] Re: Very similar to an earlier problem

[Blair Zajac]

Hi,

How often will you record this data?  RRDtool doesn't do that well
with data measured on unregular intervals.

Also, make sure you choose an interval that matches the measurement
interval you have.

Reading the RRDtool manual page on how it stores data and deals with
missing data will help out a lot in getting your data plotted.

Regards,
Blair
