Publisher description for NTP Plotter

NTP Plotter program icon

During the tests on a Windows version of the NMEA/PPS ref-clock drivers, the need arose for a simple program to plot the performance. As a result, development of the NTP Plotter program was started to produce graphs of offset, Frequency error, and jitter like those below, from the loopstats files which ntpd can produce. The jitter graph includes an extra averaged value, presented on a more detailed scale, so that even small changes can be observed, such as the change from user-mode to kernel-mode time-stamping in the bottom graph. Note that, because NTP holds the current loopstats file open, NTP Plotter may not be able to show today's data. The solution to this is to copy the loopstats files to a temporary directory, and point the NTP Plotter at that directory. Thanks to Adri Koppes for reminding me about this. I have worked round this in V1.0.8, in the Hope that any consequential incomplete data will be trapped by the program. New in beta V1.0.10.025 - Add choice of whie plot background
