[Orca-users] Re: Data not showing up on graph

[Jeff Brickley]

I only have 4 data points.  I deleted the RRD files and added about 20 more data points in the input file and ran everything again.
Still no success...everything is showing up as NaN in the .rrd file.  Attached is the output when I ran it with only 4 data points.

Thanks again for the help.
