We have encountered a case in which CSS Data Browser does not

Yes, but in different ways.
# Created by CSS Data Browser Version 2.0.5.20101112

# Start Time : 2010/11/16 20:45:00.000000000

# Desired Value Count: 1000
The export process itself requested ~1000 samples between start& end time.
The plot uses a desired value count that's configured in the under
preferences CSS/Apps/Trends/Data Browser, by default 800.
Check in the Sample view to see what data the plot actually has to determine
if the problem is in the data that the plot uses, or the plot itself.
If this is for the old Channel Archiver with the XML-RPC network data
server, you can also check the log file of the network data server
(/tmp/archserver.log) to compare
a) What the plot requests& gets
b) What the export requests& gets
I assume the reason lies in the way the data is requested, and how that's
handled by the XML-RPC network data server.
What version is your XML-RPC network data server?
Thanks,
